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.

经过溶剂萃取、大孔吸附树脂富集、Sephadex LH-20精制、制备TLC及Semi-pre HPLC等手段从中分离了20个化合物，利用理化性质和波谱技术(UV、IR、EI／MS、ESI／MS、〓H-NMR、〓C-NMR、DEPT、HMQC、HMBC)相结合鉴定了它们的结构，分别为9种蒽醌类化合物：大黄酚，大黄素甲醚，大黄素，芦荟大黄素，大黄酸，番泻苷A或B，ω-羟基大黄素(ω-hydroxylemodin)，大黄酚-8-0-β-D-葡萄糖苷(chrysophanol-8-0-β-D-glucoside)，芦荟大黄素-ω-0-β-D-葡萄糖苷(aloemodin-ω-0-β-D-glucoside)；3种菲醌类化合物：丹参酮ⅡA(tanshinoneⅡA)，隐丹参酮，丹参酮Ⅰ(tanshinone Ⅰ)；1种异黄酮：7，3'-二羟基-5'-甲氧基异黄酮（7，3'-dihydroxy-5' methoxyisofla-vone）以及原儿茶醛，原儿茶酸，黄芪甲苷(astragaloside Ⅳ)，苦杏仁苷，2，3，5，4'-四羟基二苯乙烯-2-0-β-D-葡萄糖苷（2，3，5，4'-tetrahydroxylstilbene-2-O-β-D-g1ucoside），Z—儿茶素，桂皮酸。

Aloin and Isobarbaloin are major activity for anthraquinone derivative in Aloe. It's hydrolysis to aloe-emodin-9-anthrone, and oxidant to aloe-emodin at intestine bacteria.
