Iridoid and Caffeic Glycoside Ester from the Leaf And Stem of Stachytarpheta Angustifolia (Mill) Vahl Verbenaceae
Two glycosides were isolated from the n-Butanol soluble portion of the ethanolic portion of the stem and leaves part of stachytarpheta angustifolia. Their structures were elucidated as Iridoid glycoside (1) and a caffeic glycoside ester named as –β(3 1 , 4 1 dihydroxyphenyl)–ethyl-O-α-L-rhamnopyranosyl-(1-3)-β-D-(4-O-Caffeoyl) glucopyranoside (2) by spectroscopic Method.
متن کاملEVALUATION OF ANTIMICROBIAL ACTIVITY AND PRELIMINARY PHYTOCHEMICAL STUDIES ON WHOLE PLANT OF STACHYTARPHETA JAMAICENSIS (L.)VAHL Rampratap Meena*, Pitchai R
The antimicrobial activity and preliminary phyto-chemical studies on whole plant of Stachytarpheta jamaicensis were evaluated. The shade dried and coarsely powdered plant was successively extracted with n-hexane, chloroform and alcohol in Soxhlet apparatus.

متن کاملCrystal structure of ipolamiide monohydrate from Stachytarpheta indica.
cyclopentano[c]pyran monoterpenoids and are found as natural constituents in a large number of plant families. They have been shown to possess various biological activities such as antimicrobial, antitumoral, hemodynamic, choleretic, and hepatoprotective, as well as being anti-inflammatory agents.1 However, only few examples of crystal structures of iridoids are known: for example, loganin pent...
متن کاملCNS activities of Celesia coromandeliane Vahl. in mice.
The dried extracts of aerial parts of Celesia coromandeliane Vahl. (Scrophulariaceae) were evaluated for CNS activities in mice. The methanol extract of aerial part of Celesia coromandeliane (MECC) was found to cause significant depression in general as well as exploratory behavioral profiles in mice. MECC showed reduction in muscle relaxant activity by 30 degrees inclined screen test, as well ...
متن کاملAntileishmanial Activity of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
This study aimed to evaluate the leishmanicidal activity of ethanol extract, fractions, and isolated substance from Handroanthus serratifolius against Leishmania amazonensis. Furthermore, this activity was related to cytotoxicity, and the selectivity index was determined. The ethanol extract was obtained by maceration of the stem powder, and the extract was subjected to fractionation on chromat...
