- Abstract
Two new triterpenoid glycosides, 3 α,19 α,23 α-trihydroxy-2-oxo-12-ursen-28- O- β- d-glucopyranoside ( 1) and 3 α,19 α,23 α-trihydroxy-2-oxoolean-12-en-28- O- β- d-glucopyranoside ( 2) as well as three known compounds, 2 α,3 α,19 α-trihydroxyolean-12-en-28- O- β- d-glucopyranoside ( 3), 2 α,3 α,19 α,23-tetrahydroxy-12-ursen-28- O- β- d-glucopyranoside ( 4), and 2 α,3 β,19 α,23-tetrahydroxyurs-12-en-28-oic acid ( 5) were isolated from 75% Et OH extract of Rosa cymosa. Their structures were elucidated by extensive spectroscopic methods. All the isolated compounds displayed moderate inhibitory activity against LPS-induced NO production in macrophages.
