Tripterygium doianum

From the MeOH extract of the branches of Tripterygium doianum 3P-acetoxy-1 l-ursen-13a,30-olide was isolated (34) [52]. Its IR spectrum showed a lactone carbonyl and a carbonyl band. Based on its H and C NMR spectroscopic data, compound (34) was assumed to be an ursene-type triterpene. The compound showed signal for a lactone group, an acetoxy group and a double bond. [Pg.654]
