Two new phenylethanoid glycosides integrifoliosides A (2) and B (3), along with a known phenylethanoid glycoside alyssonoside (1) and a flavone glucoside chrysoeriol-7-O-beta-D-glucopyranoside (4) were isolated from the aerial parts of Phlomis integrifolia. The structures of the new compounds were identified as 3,4-dihydroxy-beta-phenylethoxy-O-beta-D-apiofuranosyl-(1 --> 4)-alpha-L-rhamnopyranosyl-(1 --> 3)-4-O-feruloyl-beta-D-glucopyranoside (2) and 3-hydroxy-4-methoxy-beta-phenylethoxy-O-beta-D-apiofuranosyl-(1 --> 4)-alpha-L-rhamnopyranosyl-(1 --> 3)-4-O-feruloyl-beta-D-glucopyranoside (3), on the basis of spectroscopic (UV, IR, 1D- and 2D-NMR, and HR-FABMS) methods.
从糙苏地上部分分离得到两个新的苯乙醇苷类化合物全缘叶苷A(2)和B(3),以及一个已知的苯乙醇苷类化合物阿里松苷(1)和一个黄酮苷类化合物芹菜素-7-O-β-D-葡萄糖苷(4)。通过光谱方法(紫外光谱、红外光谱、一维和二维核磁共振光谱以及高分辨快原子轰击质谱)鉴定,新化合物的结构分别为3,4-二羟基-β-苯乙氧基-O-β-D-芹菜糖基-(1→4)-α-L-鼠李糖基-(1→3)-4-O-阿魏酰基-β-D-葡萄糖苷(2)和3-羟基-4-甲氧基-β-苯乙氧基-O-β-D-芹菜糖基-(1→4)-α-L-鼠李糖基-(1→3)-4-O-阿魏酰基-β-D-葡萄糖苷(3)。
