Abstract:
To investigate chemical constituents from Radix Pittospori, chloroform extract of the roots was subjected to column chromatography with various chromatographic techniques. The structures were elucidated on the basis of physico-chemical property and spectral analysis. Two triterpenoids were identified as 22-acetyl-21-(2-acetoxy-2-methylbutanoyl)-R1-barrigenol(1) and 3alpha-hydroxyl-20-demethylisoaleuritolic-14(15)-ene-28, 30-dioic acid (2). Compound 1 is a new triterpene and compound 2 is isolated from this plant for the first time.
