To further study the chemical constitutes of lipophilic active parts, we prepared Alc95% and Alc50% according to original literature. 20 compounds were isolated by using macroporous resin, silica gel, polyamide, Sephadex LH-20, Rp-18, preparative TLC and preparative HPLC chromato-graphy. The structures of them were elucidated by means of physical and chemical properties, modern spectroscopic analysis techniques—UV、IR、 EI/MS、ESI/MS、〓H-NMR、〓C-NMR、DEPT、HMQC、HMBC. They are nine anthraquinones: chrysophanol (95-1), physcion (95-2), emodin (95-5), aloemodin (95-7), rhein (50-1), sennoside A or B (50-6),ω-hydroxylemodin (95-10), chrysophanol-8-0-β-D-glucoside (95-12), aloemodin-ω-0-β-D-glucoside (95-13); three phenanthaquinones: tanshinone ⅡA (95-3), cryptotanshinone (95-6), tanshinone Ⅰ(95-4); one isoflavone: 7, 3'-dihydroxyl-5' methoxyisoflavone (95-14) and protocaechuic aldehyde (95-9), protocaechuic acid (95-11), astragaloside Ⅳ(50-4), amygdalin (50-5), 2, 3, 5, 4'-tetrahydroxylstilbene-2-0-β-D-glucoside (50-3),-catechin (50-2), cinnamic acid (95-8). Among them, 3'-dihydroxyl-5' methoxyisoflavone (95-14) is a new compound.
