从三叶委陵菜地上部分分离得到两个新的胡萝卜素A(8)和B(9)，以及其他18个化合物，包括倍半萜1和2、胡萝卜烷二萜3-7、三萜类10和11、甾体12-14、黄酮类15-17以及苯衍生物18-20。化合物A(8)和B(9)的结构通过广泛的光谱分析(包括UV、IR、核磁共振和MS)得到确证。化合物2和3的结构经X-射线单晶衍射法确证。
Two new ent-kaurane diterpenes, wedelidins A (8) and B (9), together with eighteen other constituents, including the sesquiterpenoids 1 and 2, ent-kaurane diterpenes 3 - 7, triterpenoids 10 and 11, steroids 12 - 14, and flavonoids 15 - 17 as well as benzene derivatives 18 - 20, were isolated from the aerial parts of Wedelia trilobata. The structures of wedelidins A (8) and B (9) were elucidated by extensive spectroscopic analyses (including UV, IR, NMR, and MS). Furthermore, the structures of compounds 2 and 3 were confirmed by X-ray single-crystal diffraction analyses.
