TL;DR: In this article, Vitexin and other compounds from the whole plant of Begonia picta, a Nepalese crude drug commonly known as "Magarkaanche", were isolated for the first time from B. picta.
Abstract: Vitexin (1), isovitexin (2), orientin (3), isoorientin (4) and 1,3dihydroxy6, 7dimethoxyxanthone (5) were isolated from the whole plant of Begonia picta, a Nepalese crude drug commonly known as "Magarkaanche". Structures were elucidated on the basis of chemical and spectroscopic methods. All of these compounds were isolated for the first time from B. picta and their in vitro antioxidant activity was evaluated by diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay. Compounds 3 and 4 showed significant free radical scavenging activity.

TL;DR: The results indicate the possibility that flavonoids are utilized in not only wing coloration but also as a chemical defense compound against natural threats in Pseudozizeeria maha as mentioned in this paper.
Abstract: Flavonoids in the eggs, larvae, pupae and adult butterflies of Pseudozizeeria maha were identified and quantified. Isovitexin (apigenin 6-C-glucoside) was the dominant flavonoid detected in pupae and imagines, whereas saponarin (isovitexin 7-O-glucoside) was the dominant flavonoid in larvae. Saponarin, biotransformed from isovitexin by the larvae, was found to be reconverted into isovitexin at the pupal stages. The total amounts of accumulated flavonoids differed between sexes, particularly in adults where the bodies of females had a much higher flavonoid concentration than that of the males. These flavonoids were also detected in the eggs. These results indicate the possibility that flavonoids are utilized in not only wing coloration but also as a chemical defense compound against natural threats.

TL;DR: Three megastigmane glucosides, bridelionoside B, ampelopsisionoside and 3-hydroxy-5,6-epoxy- β-ionol 9-O-β-d-glucopyranoside, together with three flavone glycosides, apigenin 7-O,β- d-glUCopyranoide, isovitexin and spinosin, were isolated from the aerial portions of
Abstract: Three megastigmane glucosides, bridelionoside B, ampelopsisionoside and 3-hydroxy-5,6-epoxy-beta-ionol 9-O-beta-D-glucopyranoside, together with three flavone glycosides, apigenin 7-O-beta-D-glucopyranoside, isovitexin and spinosin, were isolated from the aerial portions of Strophioblachia fimbricalyx. The structure determinations were based on physical data and spectroscopic evidence.
