Abstract
Three compounds (chlorophyll a, isofucosterol and saringosterol) were isolated from chloroform fraction of Sargassum thunbergii extract. The three compounds had two- to fourfold lower lipase inhibitory activity than that of the CHCl3:MeOH (C:M) (100:1) fraction (fraction I, 83.78% at 1 mg/mL). These results suggested that the high lipase inhibitory activity of fraction I was attributable to the actions of the three compounds. Therefore, S. thunbergii has potential for application as an anti-obesity agent.

Abstract
The leaves of Vernonia nigritiana Oliv. & Hiern. (Asteraceae) were investigated for their in vivo topical anti-inflammatory properties, following a bioassay-oriented fractionation approach. Petroleum ether, chloroform and chloroform-methanol extracts inhibited the Croton oil-induced ear dermatitis in mice. The chloroform extract was only about half as active as the non steroidal anti-inflammatory drug indomethacin (ID50=237 and 93 μg/cm(2), respectively). Phytochemical investigation of this extract led to the isolation of nine polyhydroxylated stigmasterol glycosides and six polyhydroxylated stigmasterols. Their structures were elucidated by NMR, MS and chemical methods. Each compound exerted a significant anti-oedema activity, the most active being 1 (3β-O-β-D-glucopyranosyloxy-5α-stigmasta-7,9(11),24(28)Z-triene-6β,16β,26,29-tetrol) and 3 (3β-O-β-D-glucopyranosyloxy-5α-stigmasta-7,9(11),24(28)Z-triene-6β,16β,29-triol), only two and five fold less potent than the steroidal drug hydrocortisone (ID50=0.10, 0.21 and 0.04 μmol/cm(2), respectively). Compound 1 (50 μM) also completely inhibited the transcription factor NF-κB in vitro.

Abstract
Although individual phlorotannins contained in the edible brown algae have been reported to possess strong anti-inflammatory activity, the responsible components of Eisenia bicyclis have yet to be fully studied. Thus, we evaluated their anti-inflammatory activity via inhibition against production of lipopolysaccharide (LPS)-induced nitric oxide (NO) and tert-butylhydroperoxide (t-BHP)-induced reactive oxygen species (ROS), along with suppression against expression of inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), in RAW 264.7 cells. The anti-inflammatory activity potential of the methanolic extract and its fractions of E. bicyclis was in the order of dichloromethane>methanol>ethyl acetate>n-butanol. The strong anti-inflammatory dichloromethane fraction was further purified to yield fucosterol. From the ethyl acetate fraction, six known phlorotannins were isolated: phloroglucinol, eckol, dieckol, 7-phloroeckol, phlorofucofuroeckol A and dioxinodehydroeckol. We found that these compounds, at non-toxic concentrations, dose-dependently inhibited LPS-induced NO production. Fucosterol also inhibited t-BHP-induced ROS generation and suppressed the expression of iNOS and COX-2. These results indicate that E. bicyclis and its constituents exhibited anti-inflammatory activity which might attribute to inhibition of NO and ROS generation and suppression of the NF-κB pathway and can therefore be considered as a useful therapeutic and preventive approach to various inflammatory and oxidative stress-related diseases.

Abstract
In the present study, we investigated the anti-diabetic potential of fucosterol by evaluating the ability of this compound to inhibit rat lens aldose reductase (RLAR), human recombinant aldose reductase (HRAR), protein tyrosine phosphatase 1B (PTP1B), and α-glucosidase. Fucosterol displayed moderate inhibitory activity against RLAR, HRAR, and PTP1B. However, it showed weak or no activity against AGE formation and α-glucosidase. In addition, our kinetic study revealed that fucosterol showed a mixed type inhibition against RLAR and HRAR, while it noncompetitively inhibited PTP1B. Since fucosterol inhibited aldose reductase (AR), it holds great promise for use in the treatment of diabetic complications. Therefore, we predicted the 3D structure of AR in rat and human using the Autodock program to simulate binding between AR and fucosterol and evaluate the binding site-directed inhibition of AR by fucosterol. Results of the docking simulations of fucosterol demonstrated negative binding energies (-8.2 kcal/mol for RLAR and -8.5 kcal/mol for HRAR), which indicated a higher affinity and tighter binding capacity of fucosterol for the active site of the enzyme. In particular, the hydrophobic ring system and the aliphatic side chain of fucosterol were found to be tightly bound in a specificity pocket through apolar amino acid residues on AR, while the anion binding site on AR interacts with the 3-hydroxyl group and the double bond on the side chain of fucosterol. The results of the present study clearly demonstrated the potential of using fucosterol for the management and treatment of diabetes and diabetes-associated complications.

Abstract
Two bioactive nematicidal phytochemicals, viz., nonacosane-10-ol and 23a-homostigmast-5-en-3β-ol, were isolated from the n-hexane fraction of the roots of Fumaria parviflora through activity-guided isolation. The structures of the compounds were elucidated using ¹³C and ¹H nuclear magnetic resonance. Activity of the two compounds against eggs and juveniles (J2s) of Meloidogyne incognita was evaluated in vitro at the concentrations of 50, 100, 150, and 200 μg mL⁻¹. Over 120 h of incubation, the cumulative percent mortality and hatch inhibition of both of the compounds tested ranged from 20 to 100% and from 15 to 95.0%, respectively. In pot trials with tomato cultivar Riogrande, the two compounds, applied as soil drenches at the concentrations of 100, 200, and 300 mg/kg, significantly decreased the nematodes and plant growth parameters. Nonacosane-10-ol and 23a-homostigmast-5-en-3β-ol reduced the numbers of galls (42.6 and 60.3), galling index (1.6 and 2.8), females per gram of root (37.3 and 57.0), eggs per gram of root (991.3 and 1273.0), reproduction factor (Rf) (0.1 and 0.2), and fresh root weight (14.33 and 17.0 g) at 300 mg/kg concentration and increased fresh shoot weight (49.0 and 48.4 g), dry shoot weight (28.0 and 25.3 g), and plant height (53.5 and 49.6 cm), respectively. These compounds could provide new insight in the search for novel nematicides against M. incognita.

Abstract
It has been reported that fucosterol has anti-diabetic, anti-oxidant, and anti-osteoporotic effects. We investigated the anti-inflammatory effects and the underlying molecular mechanism of fucosterol in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Fucosterol suppressed the expressions of inducible nitric oxide synthase (iNOS), tumour necrosis factor-α (TNF-α), and interleukin-6 (IL-6) by downregulating their transcriptions, and subsequently inhibited the productions of nitric oxide, TNF-α, and IL-6. In addition, fucosterol attenuated LPS-induced DNA binding and the transcriptional activity of nuclear factor-κB (NF-κB). These reductions were accompanied by parallel reductions in the phosphorylation and nuclear translocation of NF-κB. Furthermore, fucosterol attenuated the phosphorylations of mitogen-activated protein kinase kinases 3/6 (MKK3/6) and mitogen-activated protein kinase-activated protein kinase 2 (MK2), which are both involved in the p38 MAPK pathway. These results suggest that the anti-inflammatory effects of fucosterol are associated with the suppression of the NF-κB and p38 MAPK pathways.

Abstract
CONTEXT Celsia coromandelina Vahl (Scrophulariaceae) is a shrub found throughout Bangladesh and India, and it is distributed widely in the plains of West Bengal. It is used by the tribal people to treat diarrhea, dysentery, insomnia, skin eruption, fever, syphilis, helminthes infection, and to control fertility. OBJECTIVE The objective of this study was to fractionate stigmasterol derivative and to investigate the effects of petroleum ether extract of C. coromandelina (PECC) aerial parts on the onset of reproductive maturity and the ovarian steroidogenesis in immature female mice. MATERIALS AND METHODS PECC was prepared by hot extraction process and one compound was isolated by preparative TLC from it. PECC was completely freed from solvent and administered in immature female mice intraperitoneally once on every alternate day for nine doses. The sexual maturity was observed by means of vaginal opening, first estrus (days), rate of body growth, changes in weight of ovary, uterus and pituitary. The content of ascorbic acid, cholesterol, Δ⁵-3β-hydroxy steroid dehydrogenase (Δ⁵-3β-HSD) and glucose 6-phosphate dehydrogenase (G 6-PDH) activities in ovaries and carbonic anhydrase activity in uterus were measured by means of biochemical technique in control and treated mice. The activity of PECC was compared with standard marker compound ethinyl estradiol. RESULTS The isolated compound was characterized as stigmasterol derivative. PECC treatment caused a remarkable delay (30.27 and 18.56%, respectively, by low dose) in sexual maturity compared to vehicle control as evidenced by the age of vaginal opening and appearance of first estrus (cornified smear). PECC treatment also caused a significant fall (58.6 and 50.0%, respectively, by low dose) in Δ⁵-3β-HSD and G 6-PDH activities involved in ovarian steroidogenesis compared to vehicle control. Total cholesterol and ascorbic acid content in ovaries and carbonic anhydrase activity in uterus were increased significantly (low dose by 49.3, 424.6 and 82.4%, respectively) along with a reduction in the weight of ovary, uterus and pituitary in comparison to that of control. DISCUSSION AND CONCLUSION Overall, these results demonstrate that PECC has a good antifertility effect and is responsible for the delayed development of sexual maturity, suppression of ovarian steroidogenesis and elevation of carbonic anhydrase activity in uterus of immature mice. This supports the claim by tribal people as a potential remedy for birth control.

Abstract
CONTEXT Sapindus saponaria L. (Sapindaceae) bark, root, and fruits are used as sedatives and to treat gastric ulcer and also demonstrate diuretic and expectorant effects. OBJECTIVE The anti-snake venom properties of callus of S. saponaria are investigated here for the first time. MATERIALS AND METHODS In vitro cultivated callus of Sapindus saponaria were lyophilized, and the extracts were prepared with different solvents, before submitting to phytochemical studies and evaluation of the anti-ophidian activity. Crude extracts were fractionated by liquid-liquid partition and the fractions were monitored by thin layer chromatography (TLC). Subsequently, anti-ophidian activities were analyzed toward Bothrops jararacussu Lacerda (Viperidae), B. moojeni Hoge (Viperidae), B. alternates Duméril (Viperidea) and Crotalus durissus terrificus Lineu (Viperidae) venoms and isolated myotoxins and phospholipase A(2) (PLA(2)). RESULTS Fractions A1, A2 and the extract in MeOH:H(2)O (9:1) significantly inhibited the toxic and pharmacological activities induced by snake venoms and toxins, when compared to other extracts and fractions. The lethal, clotting, phospholipase, edema-inducing, hemorrhagic and myotoxic activities were partially inhibited by the different extracts and fractions. TLC profiles of the crude extracts (B and C) and fractions (A1 and A2) showed β-sitosterol and stigmasterol as their main compounds. Stigmasterol exhibited inhibitory effects on enzymatic and myotoxic activities of PLA(2). DISCUSSION AND CONCLUSION Sapindus saponaria extracts and fractions presented anti-ophidian activity and could be used as an adjuvant to serum therapy or for its supplementation, and in addition, as a rich source of potential inhibitors of enzymes involved in several pathophysiological human and animal diseases.

Abstract
BACKGROUND Ecdysteroids are steroid hormones that control moulting and govern several changes during metamorphoses in arthropods. The discovery of the same molecules (phytoecdysteroids) in several plant species displayed a wide array of rather beneficial agricultural impact. Many representatives of the genus Ajuga plants contain phytoecdysteroids with a 5β-7-ene-6-one system exhibiting physiological activities in insects. RESULTS By means of chromatographic (silica gel column, TLC) and LC-MS, two major ecdysteroids (20-hydroxyecdysone and cyasterone) have been isolated and identified from Israeli carpet bugle Ajuga iva (L.) Schreber (Lamiales: Lamiaceae) plants. Ajuga iva extract fractionated on the silica gel column yielded two fractions that showed high activity against the sweetpotato whitefly Bemisis tabaci and the persea mite Oligonychus perseae. A dose of 5 mg AI L(-1) of the purely identified A. iva ecdysterone significantly reduced fecundity, fertility and survival of these pests, while commercial 20-hydroxyecdysone at the same dose had lesser effects. CONCLUSION The results demonstrate considerable efficacy of natural phytoecdysteroids against major agricultural pests, and suggests that these materials should be considered for potential development of friendly control agents.
