摘 要 ：From the roots of Euphorbia prolifera Buch-Hom,collected in Yunnan,China,a new myrisinol-type diterpenoid and a new ergostanol-type triterpenoid were isolated,and their structures were elucidated on the basis of spectral and chemical methods.Their structures are I:3-acetate-5,8-dibenzoate-14-propionate a groudalkhol of myrsinoltype and II:24-methyl-5,25-cholestatrien-3β-o1.
