从三裂叶婆婆纳(Wedelia trilobata)的乙醇提取物中分离得到4个新的对映贝壳杉烷型二萜化合物,即3α-惕各酰氧基对映贝壳杉烯L3(1),对映贝壳杉烯-17-羟基-9(11),15-二烯-19-酸(2),以及wedelobatins A(3)和B(4),另外还分离得到11个已知的对映贝壳杉烷型二萜化合物(5-15)。化合物1-15的结构均经波谱学鉴定。 可通过10.1007/s13659-013-0029-4获取本文的补充材料,授权用户可访问。
Four new ent-kaurane diterpenoids, namely, 3α-tigloyloxypterokaurene L3 (1), ent-17-hydroxy-kaura-9(11),15-dien-19-oic acid (2), and wedelobatins A (3) and B (4), together with 11 known ent-kaurane diterpenoids (5-15), were isolated from the ethanol extract of Wedelia trilobata. All the structures of 1–15 were elucidated on the basis of spectroscopic studies.
