Abstract
Green synthesized silver nanoparticles (AgNPs) are becoming an important candidate for bioremediation and biomedical applications. But in recent trends, more focus is given towards degradation of dyes and application against food pathogens. The synthesis of efficient AgNPs depends on the selection of potential biological material for synthesis. Therefore, in the present study, AgNPs were synthesized using Chloroxylon swietenia. The synthesis AgNPs was confirmed by the formation of dark brown precipitate. Further physicochemical characterization performed using XRD, FTIR, SEM and DLS showed the formation of crystalline structure, presence of functional group from the C. swietenia, dispersed spherical and rod-shaped nanoparticles (6.9 nm) and possess good stability due to the negative partial charges. The dye degrading efficacy of Chloroxylon swietenia mediated synthesized AgNPs (C-AgNPs) was >95%, 90% and >90% tested against Congo red (CR), Coomassie blue (CB) and crystal violet (CV) dye, respectively withing 24 h of treatment under optimum conditions. The antibacterial activity of C-AgNPs (10 mg/mL) was analysed against Staphylococcus nepalensis (3.03 ± 0.35 cm), Staphylococcus gallinarum (2.96 ± 0.15 cm), Bacillus subtilis (2.86 ± 0.23 cm), Enterococcous faecalis (2.8 ± 0.30 cm) and Pseudomonas stuteria (2.06 ± 0.25 cm) using Disc diffusion method, Minimum inhibitory concentration (MIC) and Minimum bactericidal activity (MBC). Therefore, the present study is the first and foremost report on C-AgNPs application as dye degrading and antibacterial agents against food dyes and pathogens. This will provide a major strategy to unveil the complications in food and packaging industries worldwide.

Abstract
ETHNOPHARMALOGICAL RELEVANCE Blood purification practices, also referred to as blood cleansing or detoxification, is an ancient concept which is widespread amongst African traditional medicine, but for which no modern scientific basis exists. There prevails considerable ambiguity in defining what a blood purifier is. AIM OF THE STUDY The purpose of this review is to firstly define what a blood purifier is in the context of African traditional medicine and compare to other cultural and westernized interpretations. Thereafter, this study identifies traditionally used medicinal plants used as blood purifiers in southern Africa and correlates these species to scientific studies, which may support evidence for these "blood purifying plant species". MATERIALS AND METHODS Ethnobotanical books and review articles were used to identify medicinal plants used for blood purification. Databases such as Scopus, ScienceDirect, PubMed and Google Scholar were used to source scientific articles. An evaluation was made to try correlate traditional use to scientific value of the plant species. RESULTS One hundred and fifty nine plant species have been documented as traditional remedies for blood purification. Most of the plant species have some pharmacological activity, however, very little link to the traditional use for blood purification. There has been some justification of the link between blood purification and the use as an antimicrobial and this has been explored in many of the plant species identified as blood purifiers. Other pharmacological studies specifically pertaining to the blood require further attention. CONCLUSION Irrespective of the ambiguity of interpretation, medicinal plants used to "cleanse the blood", play an important holistic role in traditional medicine and this review with recommendations for further study provides some value of exploring this theme in the future.

Abstract
Mosquitoes transmit serious diseases, which threaten humans and severely affect livestock. The half-lethal concentration (LC50) was calculated by log probit analysis. The LC50 and LC90 values of larvicidal activity of Cassia fistula Linn. hexane-methanol soluble fraction (HMSF) after 24 h of exposure were 21.04 and 34.68 µg/ml, respectively. The LC50 values after 24 h of exposure were 84.09 µg/ml and 108.08 µg/ml for chloroform-methanol soluble fraction (CMSF) and ethyl acetate-methanol soluble fraction (EMSF) respectively. The percent hatchability of eggs exposed to the hexane extract was 90 ± 5.0, 68.33 ± 7.6, 46.6 ± 11.5, 10 ± 0.0, and 0 ± 0.0% at 10, 20, 40, 60, and 80 ppm, respectively. The pupicidal activity of the hexane extract at 40 µg/ml was 0.0%. The LC50 value of adulticidal activity of the hexane extract was 12.8 mg/test tube. The biosafety of the hexane extract was assessed in nontarget organisms, i.e., zebrafish (Danio rerio) embryos and normal lung cells (BEAS-2B). The hexane extract of C. fistula was well tolerated by zebrafish embryos, and no mortality or toxicity was found in the embryos exposed to the highest tested concentration of 300 µg/ml. Similarly, all the concentrations tested against the normal lung cells (BEAS-2B) showed more than 95% survival. The gas chromatography-mass spectroscopy analysis identified 12 compounds, and 2-methyl hexanoic acid and 2-methyl butanoic acid were the major compounds identified in the hexane extract. The larvicidal activity of C. fistula extracts will help in the development of natural substitutes for vector management of mosquito populations.

Abstract
The aim of the present study was to screen the anti-dengue potential of crude leaf extracts of two plants from Pavetta tomentosa and Tarenna asiatica. For larvicidal assay, the acetone extract of both plants showed maximum effects, with the least LC50 and LC90 values (P. tomentosa (5.968 and 7.493 μg/ml) and T. asiatica (1.288 and 1.992 μg/ml)) and the same extract of both plants exhibited better pupicidal potency. The adulticidal activity of both plants (0-60 min interval periods) recorded best results in acetone extracts and the LC50 and LC90 values were recorded as P. tomentosa (32.105 and 41.001 μg/ml) and T. asiatica (09.012 and 11.854 μg/ml). Among the two plants P. tomentosa acetone leaf extract have good antiviral property against Dengue viral cell line. In addition, the phytochemical nature of the plant reveals the presence of saponins, flavonoids and alkaloids in all the tested extracts of both plants. GC-MS analysis revealed Hexanedioic acid, Bis(2-Ethylhexyl) Ester (22.54) and 2,6,10,14,18,22- Tetracosahexane, 2,6,10, 15, 19,15,19,23- Hexamethyl-(ALL-E)- (25.33) identified as two major phytoconstitutents in P. tomentosa and Tetracontane (23.580) is a major compound identified from T. asiatica acetone extracts. The functional groups of chemical compounds (aromatis, alkanes, alkyls and carboxylic acids) from P. tomentosa and T. asiatica were analyzed by FT-IR spectrum.

Abstract
The essential oils (EOs) of Plectranthus amboinicus showed the highest larvicidal activity among four herbal plants studied and β-caryophyllene might be the major component responsible for its differential toxicity to the larvae of Culex quinquefasciatus and Aedes Aegypti. Mosquitoes act as vectors for many life-threatening diseases, including malaria, dengue fever, and Zika virus infection. Management of mosquitoes mainly relies on synthetic insecticides, which usually result in the rapid development of resistance; therefore, alternative mosquito control strategies are urgently needed. This study characterized the major component of essential oils (EOs) derived from the vegetative parts of four herbal plants and their larvicidal activity toward important mosquito vectors. The EOs were extracted by hydro-distillation and subjected to gas chromatography-mass spectrometry (GC-MS) analysis and a larvicidal activity assay toward Aedes aegypti, Ae. albopictus and Culex quinquefasciatus. In total, 14, 11, 11 and 9 compounds were identified from the EOs of Plectranthus amboinicus, Mentha requienii, Vitex rotundifolia and Crossostephium chinense, respectively. The EOs derived from four herbal plants exhibited remarkable larvicidal activity against the three mosquito species. In particular, the EOs of P. amboinicus showed the highest larvicidal activity, and the larvae of Cx. quinquefasciatus were more sensitive to the P. amboinicus EOs than that of Ae. Aegypti. Although carvacrol (61.53%) was the predominant constituent of the P. amboinicus EOs, its precursors, γ-terpinene (8.51%) and p-cymene (9.42%), exhibited the most larvicidal activity toward Ae. aegypti and Cx. quinquefasciatus. However, β-caryophyllene (12.79%) might be the major component responsible for the differential toxicity of the P. amboinicus EOs, as indicated by the significant differences in its LC50 values toward both mosquitoes. Information from these studies will benefit the incorporation of EOs into integrated vector management.

Abstract
BACKGROUND In a previous screening program for mosquitocides from local edible plants in Thailand, essential oils (EOs) of Cyperus rotundus, Alpinia galanga and Cinnamomum verum, were found to possess promising adulticidal activity against Aedes aegypti. With the aim of reducing usage of conventional insecticides and improving the management of resistant mosquito populations, this study was designed to determine the potential synergism in the adulticidal efficacy of EOs on permethrin toxicity against Ae. aegypti, both pyrethroid-resistant and -susceptible strains. METHODS EOs extracted from rhizomes of C. rotundus and A. galanga as well as C. verum barks were evaluated for chemical compositions and adulticidal activity against Muang Chiang Mai-susceptible (MCM-S) and Pang Mai Dang-resistant (PMD-R) strains of Ae. aegypti. Adulticidal bioassays of EO-permethrin mixtures for synergistic activity were also performed on these Ae. aegypti strains. RESULTS Chemical characterization by the GC-MS analytical technique demonstrated that 48 compounds were identified from the EOs of C. rotundus, A. galanga and C. verum, representing 80.22%, 86.75% and 97.24%, respectively, of all compositions. Cyperene (14.04%), β-bisabolene (18.27%) and cinnamaldehyde (64.66%) were the main constituents of C. rotundus, A. galanga and C. verum oils, respectively. In adulticidal bioassays, EOs of C. rotundus, A. galanga and C. verum were effective in killing Ae. aegypti, both MCM-S and PMD-R strains, with LD50 values of 10.05 and 9.57 μg/mg female, 7.97 and 7.94 μg/mg female, and 3.30 and 3.22 μg/mg female, respectively. The adulticidal efficacy against MCM-S and PMD-R Ae. aegypti of these EOs was close to that of piperonyl butoxide (PBO, LD50 values = 6.30 and 4.79 μg/mg female, respectively) but less pronounced than that of permethrin (LD50 values = 0.44 and 3.70 ng/mg female, respectively). Nevertheless, combination-based bioassays discovered the accomplished synergism of EOs together with permethrin. Significant synergistic effects with permethrin against both the strains of Ae. aegypti were recorded in the EOs of C. rotundus and A. galanga. Addition of C. rotundus and A. galanga oils decreased the LD50 values of permethrin against MCM-S dramatically from 0.44 to 0.07 and 0.11 ng/mg female, respectively, with synergism ratio (SR) values of 6.28 and 4.00, respectively. Furthermore, EOs of C. rotundus and A. galanga also reduced the LD50 values of permethrin against PMD-R drastically from 3.70 to 0.42 and 0.003 ng/mg female, respectively, with SR values of 8.81 and 1233.33, respectively. CONCLUSIONS The synergy of enhanced adulticidal toxicity recorded from EO-permethrin combinations against both strains of Ae. aegypti presents a promising role of EOs as a synergist for improving mosquitocidal efficacy, particularly in situations where conventional compounds are ineffective or inappropriate.

Abstract
This work investigated the content of total polyphenolic compounds and flavonoids as well as their toxicity and larvicidal and acetylcholinesterase inhibitory activities. The antioxidant activities of two medicinal Senna species extracts (Senna cana and Senna pendula) were also investigated. The ethanol extract of the leaves of S. cana and the ethanol extract of the branches of S. pendula presented the best performance in the DPPH/FRAP and ABTS/ORAC assays, respectively. For the inhibition of acetylcholinesterase, the hexane extract of the flowers of S. pendula presented the lowest IC50 value among the ethanol extracts of the leaves of S. cana and showed the best performance in some assays. The hexane extract of the leaves of S. pendula and the hexane extract of the branches of S. cana were moderate to Artemia salina Leach. In the quantification of phenols and flavonoids, the ethanol extract of the leaves of S. cana presented the best results. The ethanol extracts of the leaves of S. cana were found to be rich in antioxidants, phenolic compounds, and flavonoids. These results indicate the antioxidant potential of the extracts of Senna species and can be responsible for some of the therapeutic uses of these plants.
