Chalconoids from Fissistigma bracteolatum.
TL;DR: Phytochemical studies on the leaves of Fissistigma bracteolatum yielded five new chalconoids 2-hydroxy-3,4,6-trimethoxychalcene, and the structures of these compounds were determined by mass and NMR spectroscopic methods.
Journal ArticleDOI
Apotirucallane and Tirucallane triterpenoids from Luvunga sarmentosa.
TL;DR: The leaves of Luvunga sarmentosa yielded two new apotirucallane triterpenoids, 3-epi-skimmiarepin A and 21,23-epoxy-7alpha,21-dihydroxyapotirUCalla-14,24-dien-3-one (2), and a new tirucallanes triterpene,3-epI-flindissol (3).

TL;DR: From Fissistigma bracteolatum Chatt. (Annonaceae), a Vietnamese folk medicinal plant, the novel type natural products fissistigmatin A-D (1−4), being composed of a flavonoid and a sesquiterpene moiety, were isolated by extensive NMR techniques, MS, CD, molecular modelling calculations and X-ray analysis.
Journal ArticleDOI
Bis-indole alkaloids from Tabernaemontana bovina.
TL;DR: Three new bis-indole alkaloids, tabernaebovine and methylenebismehranine, have been isolated from the leaves and stems of Tabernaemontana bovina by NMR investigations.
Journal ArticleDOI
Indole alkaloids from Tabernaemontana bovina
TL;DR: In this paper, the indole alkaloids 3-oxomehranine and 14α,15β-dihydroxy-N-methylaspidospermine have been isolated from the leaves and stems of Tabernaemontana bovina.
