The leaves and stems of Quercus variabilis Blume afforded a new cycloartane nortriterpenoid, 3α-acetyloxy-4α, 14α-dimethyl- 9β, 19-eycloergost-24-oic acid (1), along with five known compounds (2-6). The struct...
A new triterpenoid has been isolated from the leaves and stems of Fritillaria hupehensis Hsiao et K.C. Hsia. Its structure was established as (2329-9,19-cycloart-23-ene-3α,25-diol 1 through chemical and spectroscopi...
Three new cycloartane triterpene glycosides were isolated from the rhizomes of Actaea asiatica. Their structures were elucidated as 25-ethoxyl-cimigenol-3-O-β-D-xylopyranoside 1, 2'-O-acetyl soulieoside C 2, 2'-O-a...

Six cycloartanes were isolated from ethanol extract of marine green alga Cladophora fascicularis by column chromatography. Procedure of isolation and description of these compounds are given in this paper. The structu...
A new cycloartane triterpene glycoside was isolated from the rhizome of Souliea vaginata. Its structure was established as 12-deacetyloxy-15α-hydroxy-23-epi-26-deoxyactein by spectroscopic and chemical methods.
Two novel compounds, named sphaerophyside SC and SD were isolated from the ethanolic extract of the seeds of Sphaerophysa salsula. The structures of the compounds were elucidated on the basis of the NMR data, especia...
