From the aerial parts of Phlomis longifolia var. longifolia four iridoid glucosides, shanzhiside methyl ester (1), 5-deoxypulchelloside I (2), lamalbide (3), phlomiol (4) and three phenylethanoid glycosides, verbascoside (5), forsythoside B (6), leucosceptoside A (7) along with the caffeic acid ester, chlorogenic acid (8) were isolated. The structures of the isolated compounds were established by spectroscopic (UV, IR, 1D- and 2D-NMR, FABMS) and chemical evidence. The structure elucidation of the iridoid compounds 2 and 3 are discussed in detail.
从长叶糙苏长叶变种的地上部分分离得到了四种环烯醚萜苷,即山栀苷甲酯(1)、5-脱氧普氏苷I(2)、拉马苷(3)、糙苏醇(4),三种苯乙醇苷,即毛蕊花糖苷(5)、连翘酯苷B(6)、白花蛇舌草苷A(7),以及咖啡酸酯绿原酸(8)。通过光谱法(紫外、红外、一维和二维核磁共振、快原子轰击质谱)和化学证据确定了分离得到的化合物的结构。详细讨论了环烯醚萜化合物2和3的结构解析。
