Journal ArticleDOI
Geographic distribution of three alkaloid chemotypes of Croton lechleri.
TL;DR: Three known alkaloids have been isolated for the first time from Croton lechleri, a source of the wound healing latex "sangre de grado", and three chemotypes are defined based on the alkaloid content of the leaves, and the geographic distribution is discussed.
Journal ArticleDOI
Two minor diterpene glycosides from the leaves of Stevia rebaudiana.
TL;DR: Two new new diterpene glycosides were isolated from the leaves of Stevia rebaudiana, along with the known steviol glycoside stevioside, rebaudiosides A-F and dulcoside A.

TL;DR: In this paper, three new diterpenoid glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana, and the structures of the three compounds were identified as 13-[(2-O-β-d-glucopyranosyl-β -d -glucophyrano-ylopyranoyl) oxy]-kaur-16-en-18-oic acid-(6-O -β-D-xyloprynylpolygonal-polygonyl)-β −d-gene
