Two New Triterpenoid Glycosides from Leaves of Hex chinensis SIMS1)
نویسندگان
چکیده
Two new triterpenoid glycosides were isolated (one of them as the methyl ester) as major components from leaves of Ilex chinensis Sims (Aquifoliaceae) . The structures of these glycosides, termed ilexoside A (1) and ilexoside B methyl ester (2a), have been established to be 3ƒÀ-ƒ-(ƒÀ-Dxylopyranosyl)siaresinolic acid and 3ƒÀ-ƒ-(ƒÀ-D-xylopyranosyl)pomolic acid methyl ester , respectively, based on chemical and spectral evidence . High-resolution 13C-nuclear magnetic resonance data for the methyl ester of 1 (la) and 2a are also reported .

متن کاملTwo New Cyclolignan Glycosides from Acanthus ilicifolius
Acanthus ilicifolius L. (Acanthaceae) is a spiny herb of mangrove widely distributed in southeastern Asia. In traditional Chinese medicine, it is used as an anti-inflammatory and anti-hepatitis agent. Previous pharmaceutical studies on this plant revealed that the crude alcoholic extract of its leaves showed antioxidant, hepatoprotective, antitumour and anticarcinogenic effects [1 – 2]. The con...
