Two new triterpenoids, 3β,6β-dihydroxy-12-oxo-13Hα-olean-28,19β-olide (1) and 3-oxo-olean-11,13(18)-dien-28,19β-olide (2) were isolated from the resin of Styrax tonkinensis (Pier.) Craib. The structures of both triterpenoids were determined by physicochemical and spectroscopic methods. Compound 1 is the second triterpene found with cis-fused C/D ring from the resin, which is rarely observed in oleanane-type triterpenes.
从越南安息香（Styrax tonkinensis (Pier.) Craib）的树脂中分离出两个新的三萜类化合物，3β,6β-二羟基-12-氧代-13Hα-齐墩果-28,19β-内酯（1）和3-氧代-齐墩果-11,13(18)-二烯-28,19β-内酯（2）。通过物理化学和光谱方法确定了这两个三萜类化合物的结构。化合物1是从该树脂中发现的第二个具有顺式稠合C/D环的三萜，这种结构在齐墩果烷型三萜中很少见。
