Abstract
The study was carried out to evaluate the hepatoprotective potential of aqueous methanolic extract of Heliotropium strigosum (HSME) against paracetamol induced hepatotoxicity in Swiss albino mice. The plant powder (1.5Kg) was macerated in aqueous methanol (30:70) for 7 days. The extract was evaluated for the presence of different phytochemicals and High-performance liquid chromatography (HPLC) analysis. HSME was orally administered to mice at 125, 250 and 500mg/kg for 8 days followed by paracetamol intoxication (500mg/kg orally) on the 8th day using silymarin as standard control. All the therapy was administered by oral gavage. The liver biochemical parameters and histopathological evaluation were carried out to assess changes in liver function and histology. HPLC analysis confirmed the presence of quercetin, kaempferol, and other phenolic compounds. Treatment with the extract resulted in notable (p<0.05) reduction in liver parameters in dose dependent manner. The action of HSME 500mg/kg dose was comparable to silymarin. The effect of HSME against paracetamol induced hepatotoxicity was demonstrated by protective changes in the liver histopathological which proved the traditional uses of the plant.

Abstract
Pyrrolizidine alkaloids (PAs) are genotoxic carcinogenic phytotoxins mostly prevalent in the Boraginaceae, Asteraceae and Fabaceae families. Heliotropium species (Boraginaceae) are PA-producing weeds, widely distributed in the Mediterranean region, that have been implicated with lethal intoxications in livestock and humans. In Israel, H. europaeum, H. rotundifolium and H. suaveolens are the most prevalent species. The toxicity of PA-producing plants depends on the PA concentration and composition. PAs occur in plants as mixtures of dozens of various PA congeners. Hence, the risk arising from simultaneous exposure to different congeners has to be evaluated. The comparative risk evaluation of the three Heliotropium species was based on recently proposed interim relative potency (iREP) factors, which take into account certain structural features as well as in vitro and in vivo toxicity data obtained for several PAs of different classes. The aim of the present study was to determine the PA profile of the major organ parts of H. europaeum, H. rotundifolium and H. suaveolens in order to assess the plants' relative toxic potential by utilizing the iREP concept. In total, 31 different PAs were found, among which 20 PAs were described for the first time for H. rotundifolium and H. suaveolens. The most prominent PAs were heliotrine-N-oxide, europine-N-oxide and lasiocarpine-N-oxide. Europine-N-oxide displayed significant differences among the three species. The PA levels ranged between 0.5 and 5% of the dry weight. The flowers of the three species were rich in PAs, while the PA content in the root and flowers of H. europaeum was higher than that of the other species. H. europaeum was found to pose a higher risk to mammals than H. rotundifolium, whereas no differences were found between H. europaeum and H. suaveolens as well as H. suaveolens and H. rotundifolium.

Abstract
Heliotropium is one of the most important plant genera to have conventional folklore importance, and hence is a potential source of bioactive compounds. Thus, the present study was designed to explore the therapeutic potential of Heliotropium crispum Desf., a relatively under-explored medicinal plant species. Methanolic extracts prepared from a whole plant of H. crispum were studied for phytochemical composition and possible in vitro and in silico biological properties. Antioxidant potential was assessed via six different assays, and enzyme inhibition potential against key clinical enzymes involved in neurodegenerative diseases (acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)), diabetes (α-amylase and α-glucosidase), and skin problems (tyrosinase) was assayed. Phytochemical composition was established via determination of the total bioactive contents and reverse phase ultra-high performance liquid chromatography mass spectrometry (RP-UHPLC-MS) analysis. Chemical profiling revealed the tentative presence of 50 secondary metabolites. The plant extract exhibited significant inhibition against AChE and BChE enzymes, with values of 3.80 and 3.44 mg GALAE/g extract, respectively. Further, the extract displayed considerable free radical scavenging activity against DPPH and ABTS radicals, with potential values of 43.19 and 41.80 mg TE/g extract, respectively. In addition, the selected compounds were then docked against the tested enzymes, which have shown high inhibition affinity. To conclude, H. crispum was found to harbor bioactive compounds and showed potent biological activities which could be further explored for potential uses in nutraceutical and pharmaceutical industries, particularly as a neuroprotective agent.

Abstract
Heliotropium taltalense is an endemic species of the northern coast of Chile and is used as folk medicine. The polyphenolic composition of the methanolic and aqueous extract of the endemic Chilean species was investigated using Ultrahigh-Performance Liquid Chromatography, Heated Electrospray Ionization and Mass Spectrometry (UHPLC-Orbitrap-HESI-MS). Fifty-three compounds were detected, mainly derivatives of benzoic acid, flavonoids, and some phenolic acids. Furthermore, five major compounds were isolated by column chromatography from the extract, including four flavonoids and one geranyl benzoic acid derivative, which showed vascular relaxation and were in part responsible for the activity of the extracts. Since aqueous extract of H. taltalense (83% ± 9%, 100 μg/mL) produced vascular relaxation through an endothelium-dependent mechanism in rat aorta, and the compounds rhamnocitrin (89% ± 7%; 10−4 M) and sakuranetin (80% ± 6%; 10−4 M) also caused vascular relaxation similar to the extracts of H. taltalense, these pure compounds are, to some extent, responsible for the vascular relaxation.

Abstract
Background: Medicinal plants are a source of phytochemicals and they are used for the treatment of several oxidative stress-related or other diseases for their effectiveness, low toxicity and easy availability. Five traditionally used and less characterized herbaceous weeds of West Bengal, India, namely, Heliotropium indicum, Tridax procumbens, Cleome rutidosperma, Commelina benghalensis and Euphorbia hirta, were investigated for the current research study. Methods: Aqueous and 70% ethanolic extracts of the leaves were analyzed for estimation of essential phytochemicals and to evaluate their in vitro antioxidant status, medicinal properties and cytotoxic effects. To the best of our knowledge, several assays and comparative evaluations using these herbs are reported for the first time. For quantitative study, UV-vis spectrophotometry and high-performance liquid chromatography with diode array detector HPLC-DAD techniques were used. Antibacterial properties were investigated using the Kirby-Bauer disc diffusion method. For in vitro anti-lithiatic study, a titration method was used. The cell viability assay was done using peripheral blood mononuclear cells. Results: The aqueous extract exhibits higher content of polyphenols, flavonoids, tannins and inhibition percentage values for free radical scavenging assays, whereas the 70% ethanolic extract exhibits higher content of alkaloids and cardiac glycosides. HPLC-DAD analysis of 70% ethanolic extracts led us to identify 10 predominant phenolic constituents. Euphorbia hirta extracts showed minimum cytotoxicity (cell death ~2.5% and 4% in water and 70% ethanolic extract, respectively ), whereas Cleome rutidosperma and Tridax procumbens' 70% ethanolic extracts showed higher cell death (~13% and 28%, respectively), compared with the control (cell death ~10-12%). Conclusions: The study concluded that of all the medicinal weeds selected for the current study, Euphorbia hirta possesses the highest amount of bioactive compounds and hence exhibits the highest in vitro antioxidant activity and promising in vitro medicinal properties.

Abstract
Blue heliotrope (Heliotropium amplexicaule) is an invasive environmental weed that is widely naturalized in eastern Australia and has been implicated as a source of pyrrolizidine alkaloid (PA) poisoning in livestock. Less well-documented is the potential of such carcinogenic alkaloids to contaminate honey from bees foraging on this plant species. In this study, the PA profile of H. amplexicaule plant material, determined by HRAM LC-MS/MS, revealed the presence of nine PAs and PA-N-oxides, including several PAs and PA-N-oxides of the indicine class, which have not previously been reported. The predominant alkaloid, indicine, represents 84% of the reduced PA content, with minor alkaloids identified as intermedine and the newly reported helioamplexine, constituting 7 and 9%, respectively. NMR analysis confirmed the identity of helioamplexine as a previously unreported indicine homologue. This is the first report of the isolation of intermedine, helioamplexine, and 3'-O-angelylindicine from H. amplexicaule. Also described is the identification of N-chloromethyl analogues of the major alkaloids as isolation-derived artifacts from reactions with dichloromethane. Analysis of regional-market honey samples revealed a number of honey samples with PA profiles analogous to that seen in H. amplexicaule, with measured PA contents of up to 2.0 μg of PAs per gram of honey. These results confirm the need for honey producers to be aware of H. amplexicaule as a potential PA source, most particularly in products where honey is sourced from a single location.

Abstract
Heliotropium indicum L. belongs to the family Boraginaceae. The plant has been used as a folk medicine because it contains substances of various biological activities. It is also identified as a common weed which grows wildly in crop fields in tropical and subtropical regions of the world. However, there is little information on the allelopathic effect in this plant. Therefore, this study was undertaken to investigate the growth inhibitory effect and to identify the growth inhibitory substances in H. indicum. An aqueous methanol extract of H. indicum inhibited shoot and root growth of barnyard grass, foxtail fescue, timothy, cress, lettuce and rapeseed at concentrations higher than 10 mg dry weight equivalent extract/mL. The concentrations required for 50% growth inhibition (I50) of those test plants ranged from 3-282 mg dry weight equivalent extract/mL. The extract was then separated using a sequence of chromatographic fractionations and a growth inhibitory substance was isolated and identified by spectral analysis as methyl caffeate. Methyl caffeate inhibited the growth of lettuce and foxtail fescue at concentrations higher than 1.0 mM. The results suggest that methyl caffeate may contribute to the growth inhibitory effect of H. indicum and may play an important role in the allelopathic effect of H. indicum.

Abstract
In this study, we seek to identify flavonoids able to regulate the gene expression of a group of cytokines important for the control of infections in Atlantic salmon (Salmo salar). Particularly, we studied the potential immunomodulatory effects of two flavonoids, Alpinone and Pinocembrine, which were isolated and purified from resinous exudates of Heliotropium huascoense and Heliotropium sinuatum, respectively. The transcript levels of TNF-α and IL-1 (inflammatory cytokines), IFN-γ and IL-12 (T helper 1 type cytokines), IL4/13A (Th2-type cytokine), IL-17 (Th17 type cytokine) TGF-β1 (regulatory cytokine) and IFN-α (antiviral cytokine) were quantified by qRT-PCR in kidneys of flavonoid-treated and control fish. We demonstrated that the administration of a single intramuscular dose of purified Alpinone increased the transcriptional expression of five cytokines, named TNF-α, IL-1, IFN-α, IFN-γ and TGF-β1 in treated fish compared to untreated fish. Conversely, administration of purified Pinocembrine reduced the transcriptional expression of TNF-α, IL-1 and IL-12 in the kidney of treated fish. No other changes were observed. Interestingly, Alpinone also induced in vitro antiviral effects against Infectious Salmon Anaemia virus. Results showed that Alpinone but not Pinocembrine induces the expression of cytokines, which in vertebrates are essential to control viral infections while Pinocembrine reduces pro-inflammatory cytokines. Altogether results suggest that Alpinone is a good candidate to be further tested as immunostimulant and antiviral drug.

Abstract
Heliotropiumz stnigosum Wilid. (Boraginaceae) is used traditionally as a laxative, diuretic, and as a treatment for snake bites and stings of nettles. Recent investigations have shown anti-inflammatory and antioxidant activity of H. sorigosum. However, antihyperglycemic and antidyslipidemic activity of H. strigosum has not been investigated to date and we aimed to explore these activities of the crude aqueous methanolic extract of thEaerial parts of H. strigosum (Hs.Cr). Hs.Cr was administered orally at doses of 100, 300, and 500 mg/kg in alloxan-induced diabetic rats (type I diabetes) and fructose-fed rats (type II diabetes). The fasting blood glucose (FBG) concentration was assessed by glucometer, while semum total cholesterol, triglycerides and HDL were estimated by using standard kits. The FBG concentration significantly (p < 0.05) decreased in dose-dependent pattern in both alloxan-induced diabetic and fructose-fed rats on Hs.Cr administration. The percentage glucose reductions in alloxanized rats with glibenclamide, Hs.Cr 100, 300, and 500 mg/kg were obeserved to be 67, 36, 56 and 62%, respectively. In fructose-fed rats, the percentage glucose redutions associated with metformin, Hs.Cr 100, 300, and 500 mg/kg were 23, 5, 11 and 12%, respectively. The extract also corrected the dyslipidemia associated with fructose and alloxan-induced diabetes by significantly (p < 0.00 1) decreasing the concentration of serum total cholesterol, triglycerides and LDL and by increasing HDL concentration. Our data demonstrate that the H. stigosum has antidiabetic and antidyslipidemic effects, thus encouraging further studies.

Abstract
Filifolinone is a semi-synthetic terpenoid derivative obtained from Heliotropium filifolium that increases the expression level of pro-inflammatory and anti-inflammatory cytokines in kidney cells of salmon. Because cytokines are produced in response to a foreign organism and by distinct other signals modulating immune responses, we further studied the potential immunomodulatory effects of a group of structural related terpenoid derivatives from H. filifolium on salmonids to determine the relationship between the chemical structure of the derivatives and their ability to modify cytokine expression and the lymphoid content. The resin and four 3H-spiro 1-benzofuran-2,1'-cyclohexane derivatives were tested in vivo in rainbow trout (Oncorhynchus mykiss) by quantifying the transcript levels of antiviral and T helper-type cytokines and T and B cells in the kidney. Three of the four terpenoids differ only in the C-7'substituent of the cyclohexane and the presence of the ketone group at this position in Filifolinone appeared responsible of an important up-regulation of IFN-α1, IFN-γ, IL-4/13A and IL-17D in the kidney of the treated trout. In addition, the absence of a methoxy group in carbon 7 of the benzene ring, found in all compounds but not in Folifolinoic acid, produced a significant reduction of IFN-γ, IL-12 and IL-4/13A transcripts. B cells were not affected by the compound treatment but Filifolinoic acid and the resin induced a significant reduction of T cells. Altogether, results showed that immunomodulating responses observed in the trout by effect of 3H-spiro 1-benzofuran-2,1'-cyclohexane derivatives is related to the presence of the ketone group in the carbon 7' and the methoxy group in carbon 7 of the benzene ring, being Filifolinone the most active immunostimulatory compound identified.

Abstract
Pyrrolizidine alkaloids (PAs) are carcinogenic and genotoxic phytochemicals found exclusively in angiosperms. The ingestion of PA-containing plants often results in acute and chronic toxicities in man and livestock, targeting mainly the liver. During February 2014, a herd of 15-18-month-old mixed-breed beef cattle (n = 73) from the Galilee region in Israel was accidently fed hay contaminated with 12% Heliotropium europaeum (average total PA intake was 33 mg PA/kg body weight/d). After 42 d of feed ingestion, sudden death occurred over a time period of 63 d with a mortality rate of 33%. Necropsy and histopathological examination revealed fibrotic livers and moderate ascites, as well as various degrees of hyperplasia and fibrosis of bile duct epithelial cells. Elevated γ-glutamyl-transferase and alkaline phosphatase levels were indicative of severe liver damage. Comprehensive PA profile determination of the contaminated hay and of native H. europaeum by LC-MS/MS revealed the presence of 30 PAs and PA-N-oxides, including several newly reported PAs and PA-N-oxides of the rinderine and heliosupine class. Heliotrine- and lasiocarpine-type PAs constituted 80% and 18% of the total PAs, respectively, with the N-oxides being the most abundant form (92%). The PA profile of the contaminated hay showed very strong resemblance to that of H. europaeum.

Abstract
Heliotropium bacciferum is paramount in medicinal perspective and belongs to Boraginaceae family. The crude and numerous fractions of leaves, stem, and roots of the plant were investigated for phytochemical analysis and DPPH radical scavenging activity. Phytochemical analysis of crude and fractions of the plant revealed the presence of alkaloids, saponins, tannins, steroids, terpenoids, flavonoids, glycosides, and phenols. The antioxidant (free radical scavenging) activity of various extracts of the Heliotropium bacciferum was resolute against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical with the avail of UV spectrophotometer at 517 nm. The stock solution (1000 mg/mL) and then several dilutions (50, 100, 150, 200, and 250 mg/mL) of the crude and fractions were prepared. Ascorbic acid was used as a standard. The plant leaves (52.59 ± 0.84 to 90.74 ± 1.00), stem (50.19 ± 0.92 to 89.42 ± 1.10), and roots extracts (49.19 ± 0.52 to 90.01 ± 1.02) divulged magnificent antioxidant activities. For the ascertainment of the fatty acid constituents a gas chromatograph hyphenated to mass spectrometer was used. The essential fatty acids for growth maintenance such as linoleic acid (65.70%), eicosadienoic acid (15.12%), oleic acid (8.72%), and palmitic acid (8.14%) were found in high percentage. The infrared spectra of all extracts of the plant were recorded by IR Prestige-21 FTIR model.

Abstract
Diseases transmitted by blood-feeding mosquitoes, such as dengue fever, dengue hemorrhagic fever, Japanese encephalitis, malaria, and filariasis, are increasing in prevalence, particularly in tropical and subtropical zones. To control mosquitoes and mosquito-borne diseases, which have worldwide health and economic impacts, synthetic insecticide-based interventions are still necessary, particularly in situations of epidemic outbreak and sudden increases of adult mosquitoes. Green nanoparticle synthesis has been achieved using environmentally acceptable plant extract and eco-friendly reducing and capping agents. In view of the recently increased interest in developing plant origin insecticides as an alternative to chemical insecticide, in the present study, the adulticidal activity of silver nanoparticles (AgNPs) synthesized using Heliotropium indicum plant leaf extract against adults of Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus was determined. Adult mosquitoes were exposed to varying concentrations of aqueous extract of H. indicum and synthesized AgNPs for 24 h. AgNPs were rapidly synthesized using the leaf extract of H. indicum, and the formation of nanoparticles was observed within 6 h. The results recorded from UV-vis spectrum, Fourier transform infrared, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy support the biosynthesis and characterization of AgNPs. The maximum efficacy was observed in synthesized AgNPs against the adult of A. stephensi (lethal dose (LD)₅₀ = 26.712 μg/mL; LD₉₀ = 49.061 μg/mL), A. aegypti (LD₅₀ = 29.626 μg/mL; LD₉₀ = 54.269 μg/mL), and C. quinquefasciatus (LD₅₀ = 32.077 μg/mL; LD₉₀ = 58.426 μg/mL), respectively. No mortality was observed in the control. These results suggest that the leaf aqueous extracts of H.indicum and green synthesis of AgNPs have the potential to be used as an ideal eco-friendly approach for the control of the A. stephensi, A. aegypti, and C. quinquefasciatus. This is the first report on the adulticidal activity of the plant extracts and AgNPs.

Abstract
Southern hairy-nosed wombats (Lasiorhinus latifrons) inhabiting degraded habitat in South Australia were recently identified with extensive hair loss and dermatitis and were in thin to emaciated body condition. Pathological and clinicopathological investigations on affected juvenile wombats identified a toxic hepatopathy suggestive of plants containing pyrrolizidine alkaloids, accompanied by photosensitive dermatitis. Hepatic disease was suspected in additional wombats on the basis of serum biochemical analysis. Preliminary toxicological analysis performed on scats and gastrointestinal contents from wombats found in this degraded habitat identified a number of toxic pyrrolizidine alkaloids consistent with ingestion of Heliotropeum europaeum. Although unpalatable, ingestion may occur by young animals due to decreased availability of preferred forages in degraded habitats and the emergence of weeds around the time of weaning of naive animals. Habitat degradation leading to malnutrition and ingestion of toxic weed species is a significant welfare issue in this species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Senescent leaves of Heliotropium foertherianum Diane & Hilger (Boraginaceae) are traditionally used in the Pacific region to treat Ciguatera Fish Poisoning. This plant contains rosmarinic acid that is known for its multiple biological activities. In the present study, H. foertherianum aqueous extract, rosmarinic acid and its derivatives were evaluated for their capacity to reduce the effect of ciguatoxins. MATERIALS AND METHODS Aqueous extract of H. foertherianum leaves was prepared and studied for its effects against a Pacific ciguatoxin (P-CTX-1B) in the neuroblastoma cell assay and the receptor binding assay. Rosmarinic acid and six derivatives were also evaluated by means of these bioassays. For this purpose, we have developed an improved synthetic route for caffeic acid 3,4-dihydroxy-phenethyl ester (CADPE). RESULTS Both the aqueous extract of H. foertherianum leaves and rosmarinic acid showed inhibitory activities against a Pacific ciguatoxin in the above bioassays. Among all the molecules that were evaluated, rosmarinic acid was the most active compound. CONCLUSION These results confirm further the potential of H. foertherianum in the treatment of Ciguatera Fish Poisoning.

Abstract
Careful reevaluation of the 1H and 13C NMR spectroscopic data of filifolinol acetate (4) led to the reassignment of the C-10 and C-11 signals, as well as the gem-dimethyl signals. Single crystal X-ray analysis provided an independent structural confirmation of 4, and comparison of the experimental vibrational circular dichroism spectrum with calculations performed using density functional theory provided the absolute configuration of this 3H-spiro-1-benzofuran-2,1'-cyclohexane and related molecules.

Abstract
The different solvent extracts (viz Petroleum ether Ethyl acetate and Methanol) obtained from leaves and flowers of Heliotropium indicum and Spilanthes calva were screened for antifeedant activity against Helopeltis theivora. All the six different extracts showed antifeedant activity at four different concentrations. The methanolic extracts of leaves of Heliotropium indicum and Spilanthes calva exhibited significant activity at 4% concentration. The numbers of spots produced were only 18.67 and 22.67 respectively which are significantly less than the numberof spots produced in control (104.00 and 93.33 respectively). The treatment with methanolic extracts of flowers of both the plants significantly reduced the number of feeding spots to 22.33 and 23.67 respectively in comparison to the control values of 101.33. All the activities are dose dependent. The mean results with SEM (mean +/- SE) were statistically significant at 1% level (p<0.01) for three observations.

Abstract
H. taltalense (Phil.) Johnst. (Heliotropiaceae) is an endemic species of the northern coast of Chile that produces a resinous exudate that covers its foliar surface and stems. Its chemical composition was analyzed for the first time, and two aromatic geranyl derivatives: filifolinol and filifolinyl senecionate and three flavonoids – naringenin, 3-O-methylgalangin and 7-O-methyleriodictiol – were isolated. The antioxidant activity of the flavonoids and the resinous exudates was carried out by measuring the 1,1-diphenyl-2-picrylhydrazyl (DPPH) bleaching effect in ethanolic solution and in sodium dodecyl sulfate (SDS) micelles. The influence of the reaction medium was analyzed. The initial velocity reactions for the pure compounds and for the extract were higher in SDS media than in ethanolic solution. The velocity of reaction observed was interpreted in terms of the reaction medium environment in the micelle.

Abstract
The essential oils of four plant species from Nigeria have been extracted by hydrodistillation and analyzed by GC and GC-MS. The oils of Cajanus cajan were comprised of sesquiterpenes (92.5%, 81.2% and 94.3% respectively in the leaves, stem and seeds). The major compounds identified were alpha-himachalene (9.0-11.5%), beta-himachalene (8.0-11.0%), gamma-himachalene (6.9-8.1%), alpha-humulene (7.1-8.7%) and alpha-copaene (4.5-5.6%). However, monoterpenoid compounds (81.8%) dominated the oil of Moringa oleifera with an abundance of alpha-phellandrene (25.2%) and p-cymene (24.9%). On the other hand, aldehydes (52.8%) occurred in the highest amount in Heliotropium indicum, represented by phenylacetaldehyde (22.2%), (E)-2-nonenal (8.3%) and (E, Z)-2-nonadienal (6.1%), with a significant quantity of hexahydrofarnesylacetone (8.4%). The leaf and stem oils of Bidens pilosa were dominated by sesquiterpenes (82.3% and 59.3%, respectively). The main compounds in the leaf oil were caryophyllene oxide (37.0%), beta-caryophyllene (10.5%) and humulene oxide (6.0%), while the stem oils had an abundance of hexahydrofarnesyl acetone (13.4%), delta-cadinene (12.0%) and caryophyllene oxide (11.0%). The observed chemical patterns differ considerably from previous investigations.

The new bioactive sesquiterpenoid (3R,6E)-2,6,10-trimethyl-3-(3-p-hydroxyphenylpropanoyloxy)-dodeca-6,11-diene-2,10-diol, named megalanthine, was isolated from the resinous exudates of Heliotropium megalanthum. The degradation products of this compound were identified. Several plant-defensive properties (insecticidal, antifungal, and phytotoxic) were evaluated after obtaining positive results in a preliminary etiolated wheat coleoptile bioassay. This bioassay showed the need to have both the phenolic and sesquiterpene moieties of the natural product present to achieve a biological effect. This result was confirmed in phytotoxicity bioassays. Megalanthine was ruled out as a significant plant-plant defense agent because of its lack of stability. The positive results recorded in the antifungal and antifeedant tests suggest, however, that this chemical is relevant in several ecological interactions involving H. megalanthum.

Abstract
From our screening program, we identified the anti-inflammatory effects of the extracts of Heliotropium ovalifolium in its ability to inhibit specific cytokines. The H. ovalifolium extract was found to be moderately active with an IC(50) equaling 10 microg/ml for inhibition of interleukin-6 (IL-6) in a human monocytic cell line. Interleukin-6 is a pleiotropic cytokine with implications in the regulation of the immune response, inflammation and hematopoiesis. This prompted us to examine and identify the active molecules that are responsible for the bioactivity in THP-1 cells. Bioassay guided fractionation identified two compounds 4,7,8-trimethoxy-naphthalene-2-carboxylic acid and 6-hydroxy-5,7-dimethoxy-naphthalene-2-carbaldehyde with an IC(50) of 2.4 and 2.0 microM for IL-6 inhibition and an IC(50) of 15.6 and 7.0 microM for tumor necrosis factor-alpha (TNF-alpha) inhibition in THP-1 cells. The protein expression data were supported by the inhibitory effect on mRNA gene expression. The compounds isolated from H. ovalifolium were also non-toxic in human peripheral blood monocytes from normal donors and the activity profile was similar to that obtained on THP-1 cells. Thus, we believe that these scaffolds may be of interest to develop leads for treating rheumatoid arthritis, psoriasis, ulcerative colitis, Crohn's disease and other inflammatory disorders. However, more detailed investigations need to be carried out to explain the efficacy of these compounds as drugs.

Abstract
A re-examination of cuticular components of Heliotropium filifolium allowed the isolation of four new compounds: 3’-hydroxy-2’,2’,6’-trimethyl-3H-spiro[1-benzo-furan-2,1’-cyclohexane]-5-carboxylic acid (2), methyl 3’-acetyloxy-2’,2’,6’-trimethyl-3H-spiro[1-benzofuran-2,1’-cyclohexane]-5-carboxylate (3), methyl 3’-isopentanoyloxy-2’,2’,6’-trimethyl-3H-spiro[1-benzofuran-2,1’-cyclohexane]-5-carboxylate (4) and methyl 3’-benzoyloxy-2’,2’,6’-trimethyl-3H-spiro[1-benzofuran-2,1’-cyclohexane]-5-carboxylate (5). Compounds 2-5 were identified by their spectroscopic analogies with filifolinol (1), and their structures confirmed by chemical correlation with 1. The antimicrobial properties of the compounds were tested against Gram positive and Gram negative bacteria. Some of them proved to be active against Gram positive, but inactive against Gram negative bacteria. In searching for structure-activity relationships from the obtained MIC values, lipophilicity was shown to be an important variable.

Abstract
Heliotropium glutinosum Phil. (Heliotropiceae) is a resinous bush that grows at a height of 2000 m in Chañaral, Chile. From the resinous exudates of Heliotropium glutinosum Phil. a new aromatic geranyl derivative: 4-methoxy-3-[(2)-7'-methyl-3'-hydroxymethyl-2',6'-octadienyl] phenol (1) and three flavonoids: 5,3'-dihydroxy-7,4'-dimethoxyflavanone (2), 5,4'-dihydroxy-7-methoxyflavanone (3) and 4'-acetyl-5-hydroxy-7-methoxyflavanone (4) were isolated and their structures were determined. Their antioxidant activity were evaluated using the bleaching of ABTS and DPPH derived cation radical methods and expressed in terms of FRE (fast reacting equivalents) and TRE (total reacting equivalents), where FRE is a good measure of the quick protection of a given compound against oxidants and TRE measures the degree of long-term protection of the antioxidant, or how effective it is against a strong oxidative stress.

Abstract
The potential role of the methanolic extract of Heliotropium zeylanicum (BURM.F) LAMK (MEHZ) in the treatment of diabetes along with its antioxidant and antihyperlipidemic effects was studied in streptozotocin-induced diabetic rats. Oral administration of (MEHZ) 150 and 300 mg/kg/d for 14 d significantly decreased the blood glucose level and considerably increased the body weight, food intake, and liquid intake of diabetic-induced rats. MEHZ significantly decreased thiobarbituric acid reactive substances and significantly increased reduced glutathione, superoxide dismutase and catalase in streptozotocin-induced diabetic rats at the end of 14 d of treatment. The study also investigated the antihyperlipidemic potential of MEHZ. The results show that the active fraction of MEHZ is promising for development of a standardized phytomedicine for the treatment of diabetes mellitus.

Abstract
Relationships between the structural characteristics of flavonoids isolated from the resinous exudate of Heliotropium sinuatum and their antioxidant activity were studied. Radical formation energies, DeltaH of dehydrogenation and spin densities were calculated using DFT methods (B3LYP/6-31G*). Results show that studied flavonoids can be divided into two sets according to their activity. It has been found that antioxidant activity depends both on substitution pattern of hydroxyl groups of the flavonoid skeleton and the presence of an unsaturation at the C2-C3 bond. A good tendency between DeltaH of dehydrogenation and antioxidant activity was established.

Abstract
Heliotropamide (1), a new alkaloid with a novel oxopyrrolidine-3-carboxamide central moiety, has been isolated as the major product of the dicholoromethane extract of Heliotropium ovalifolium aerial parts. Its structure was elucidated by spectrometric methods including ESI-HR, EI, D/CI mass spectrometry, (1)H, (13)C, and 2D NMR experiments, and chemical derivatization. Neither heliotropamide nor its acetylated derivative (1a) showed any antifungal activity against Cladosporium cucumerinum and Candida albicans, antibacterial activity against Bacillus subtilis, radical-scavenging properties in the DPPH test, or inhibitory potential toward acetylcholinesterase.

Abstract
The ethanolic extracts of Heliotropium indicum, Plumbago zeylanicum and Acalypha indica were evaluated for their wound healing activity in rats. Wound healing activity was studied using excision and incision wound models in rats following topical application. Animals were divided into four groups with six in each group. Ten percent w/v extract of each plant was prepared in saline for topical application. H. indicum possesses better wound healing activity than P. zeylanicum and A. indica. Tensile strength results indicate better activity of H. indicum on remodeling phase of wound healing.

Abstract
Five groups of 20 female broiler chicks were fed different levels of dehulled Heliotropium dolosum seed (w/w%; 0.0, 1.0, 3.0, 5.0 or 10.0%) from 10 to 52 d of age. In all doses the seed caused decreases in daily feed intake, weight gain, and feed efficiency, and biochemical findings, severity of pathologic changes, and mortality rate increased in a dose-dependent manner. Acute toxicity was observed in livers of chicks fed 10% seed. Other test groups had chronic changes. Livers had massive to submassive necrosis, hepatic megalocytosis, bile duct proliferation, fatty change, and periportal fibrosis. Biochemical evaluations revealed hypoalbuminemia, hypoprotienemia and increased ALP activity and billuribin. The seed of Heliotropium dolosum produced biochemical and specific pathologic changes in broiler chicks, as well as decreased food intake and feed efficiency. Higher seed levels induced more pronounced changes.

Abstract
The seeds and roots of Heliotropium lasocarpium, contain a pyrrolizidine alkaloid which causes toxic liver injury and veno-occlusive disease (VOD), characterised by an occlusive lesion of the centrolobular veins of the liver, when consumed by humans. The Farkhar region of Southern Tadjikistan, was blockaded from May to November 1992. This led to a famine and a delay of two months in the wheat harvest. Heliotropium lasocarpium had time to grow in the fields and their seeds were therefore collected with the wheat. The contaminated wheat was distributed to the population, who milled it and made bread. The first case of liver toxicity was six weeks after the first consumption of the contaminated bread. By March 1993, 3,906 cases had been recorded (attack rate = 4%). The attack rate were 0.4%, 5.4%, 4.0%, 2.8% and 1.5% for the less than 1 year, 1-14 years, 15-30 years, 31-50 years and over 50 years age groups respectively. The overall case fatality ratio (CFR) was 1.3% and increased with age from 0 to 5.9% in the same age groups. Two of the ten collective farms represented 83.3% of the cases attack rate of 16.9% and 23.6%. Four stages of illness were defined. Stage I corresponds to abdominal pain, nausea or vomiting, and asthenia. All stage I patients (55.5%) recovered rapidly. Stage II is an association of Stage I and hepatomegalia (29.9%). Stage III includes ascites in addition to these symptoms (13.7%) and stage IV alteration of consciousness (0.9%). The last case was reported on March 4th 1993.(ABSTRACT TRUNCATED AT 250 WORDS)
