Abstract
Seven undescribed polyoxygenated ursane-type triterpenoids (vitnegundins A-G), three undescribed triterpenoid saponins (vitnegundins H-J), and 17 known ones were isolated from an EtOH extract of the aerial parts of Vitex negundo L. The structures of the undescribed compounds were established by extensive spectroscopic analysis. The absolute configurations of vitnegundins A, B, and E were determined by single-crystal X-ray diffraction data. Vitnegundins B-D are pentacyclic triterpenoids possessing rare cis-fused C/D rings and vitnegundins C-H represent undescribed ursane-type triterpenoids with 12,19-epoxy moiety. In the biological activity assay, vitnegundin A, vitnegundin E, and swinhoeic acid displayed inhibitory effects against LPS-induced NO release in BV-2 microglial cells, with IC50 values of 11.8, 44.2, and 19.6 μM, respectively.

Abstract
A new labdane-type diterpenoid, named vitexnegundin (1), along with seven known compounds, including vitexilactone (2), vitetrifolin D (3), 13-hydroxy-5(10),14-halimadien-6-one (4), (rel 3S,5S,8R,9R,10S)-3,9-dihydroxy-13(14)-labden-16,15-olide (5), artemetin (6), vitexcarpin (7) and penduletin (8), were isolated from the leaves of Vitex negundo L. Their structures were elucidated by using spectroscopic methods, X-ray crystallographic analysis and comparison with those reported in the literature. Moreover, all isolated compounds 1-8 were evaluated for their antimicrobial activity against ESBL-producing Escherichia coli strain and methicillin-resistant Staphylococcus aureus.

Abstract
Experimental studies has been carried out to isolate and identify an active antifilarial compound from Vitex negundo L. plant as it has been used for treatment against filariasis in Indian traditional system of medicine. In vitro antifilarial assay has been carried out against adult filarial parasite Setaria cervi worms by both worm motility and MTT reduction assays. Levels of oxidative stress parameters MDA, carbonyl content and nitric oxide levels have been detected. The isolated compound exhibited significant antifilarial activity in dose dependent manner. The active compound has been chemically characterized and identified as 4,5-diethyl-3′-ethoxy-pyro-flavone. 4,5-Diethyl-3′-ethoxy-pyro-flavone: next-generation drug for lymphatic filariasis Vitex negundo L. has bioactivity against cattle-endosymbiont Setaria cervi. Isolated drug has oxidative and/or nitrosative activity.

Abstract
It is believed that nanoemulsions were emerged as a promising candidate to improve the qualities of natural essential oil towards antimicrobial and insecticidal applications. In the present study, we have focused on the encapsulation of Vitex negundo L. leaf essential oil using Polysorbate80 for its different biological activities including antioxidant, bactericidal and larvicidal activity against dengue fever vector Aedes aegypti L. Initially, the nanoemulsion was prepared by low energy method and droplet size of the formulated nanoemulsion was characterized by using Dynamic Light Scattering analysis. The freshly prepared V. negundo essential nanoemulsion was observed with the mean droplet size of below 200 nm indicating its excellent stability. Further, the larvicidal activity of essential oil and nanoemulsion with various concentrations (25, 50, 100, 200 and 400 ppm). The larvicidal activities were tested 2nd and 3rd instar larval mortality rate that was observed against the 12 and 24 h exposure period. After a 12 h exposure period, the larvicidal activities of 2nd instar larva were observed as essential oil (73.33 ± 1.88), nanoemulsion (81.00 ± 0.88) and the larvicidal activities of 3rd instar larva were displayed essential oil (70.33 ± 2.60) and nanoemulsion (79.00 ± 3.70). Likewise, after a 24 h exposure period, the larvicidal activities of 2nd instar larva were observed as essential oil (90.30 ± 2.15), nanoemulsion (94.33 ± 1.20) and the larvicidal activities of 3rd instar larva were essential oil (80.66 ± 0.66) and nanoemulsion (93.00 ± 1.25) respectively. We finally concluded that the developed plant-based emulsion essential oil systems were thermodynamically stable. Owing to its improved bioavailability and biocompatibility, formulated nanoemulsion can be used in various biomedical applications including drug delivery as well as disease transmitting mosquito vector control.
