Abstract: Chemical investigation of Dragon's blood resin from Dracaena cochinchinensis in Yunnan yielded five aromatic compounds, ethyl-p-hydroxy benzoate(l), 7,4'-dihydroxyflavan (2), 7-hydroxy-4'-methoxyflavan(3), 7,4'-dihydroxyflavone (4) and lourerin (5) as well as a known steroid saponin (6). Three aromatic compounds showed antifungal activity. In addition, three kinds of domestic Dragon's blood resin from different regions and one kind of the imported were examined with TLC. The results indicated that the chemical constituents of the domestic dragon's blood resin were very similar, while the imported one was quite different.

Key words: Dragon's blood resin

摘要： 云南血竭为剑叶龙血树(Dracaena cochinchinensis(Lour.)S．C．Chen)树脂，从中分离到5个芳香族化合物：对羟基苯甲酸乙酯(l)，7，4'-二羟基黄烷(2)，7-羟基-4'-甲氧基黄烷(3)，7，4'-二羟基黄酮(4)和loureirin A(5)以及1个甾体皂甙(6)，并对其中3个酚性成分进行了抗真菌活性检测。另外，用薄层层析法对云南血竭、广西血竭、海南血竭及进口“皇冠牌”血竭的化学成分进行了比较，结果表明国产3种血竭的化学成分极相似，而与进口血竭不同。
