血竭是麒麟竭 Daemonogops draco B1. 的果实中分泌出来的浆汁,经干燥后形成一种红色树脂状的粉末或颗粒。以前曾从其中分离到几种黄酮类物质(1)和(2)和一种开环为二聚黄酮(3),以及另一种新颖的draco-ox 作者将干燥后的血竭(100g)在沙氏提取器中用正己烷提取后,再将残渣用醋酸乙酯提取,其正己烷部分中含有(1)及(2)黄酮;醋酸乙酯部分中经色层分离得到化合物(5),为一种开环的新颖三黄酮。结构式分别如下:
Dragon’s Blood is a syrup that is secreted from the fruit of the unicorn dried Daemonogops draco B1. After drying, it forms a red resinous powder or granules. Previously isolated from it were several flavonoids (1) and (2) and one that was ring-opened to diflavone (3), and another novel draco-ox author would dry up the dried blood (100 g) After extraction with n-hexane in a Sabim extractor, the residue was extracted with ethyl acetate. The n-hexane portion contained (1) and (2) flavonoids; ethyl acetate was chromatographed to give Compound (5). , a novel ring-opening triflavonoid. The structural formulas are as follows:
