印度马缨丹Lantana indica是一种印度药用植物。具有镇咳、发汗、肠道消毒作用。印度阿育吠陀医学中用于治疗破伤风、风湿病和疟疾。曾报道从马缨丹属植物五色梅Lantana camara和印度马缨丹中分离到齐墩果烷、乌斯烷(ursane)、羽扇豆烷(lupane)等三萜类化合物。本文报道从印度马缨丹中分离一个新的齐墩果烷五环三萜酸,并对其结构进行了鉴定。取印度马缨丹的阴干粉碎根(4.0kg),在沙氏提取器中用氯仿提尽。提取液(50g)减压浓缩,经硅胶G柱层析,依次用石油醚
Lantana indica is an Indian medicinal plant. Has antitussive, sweating, intestinal disinfection. Indian Ayurvedic medicine is used to treat tetanus, rheumatism and malaria. It has been reported that triterpenoids such as oleanane, ursane, and lupane were isolated from Lantana camara and Lantana camara in the Lantana. This paper reports the isolation of a new oleanane pentacyclic triterpenoic acid from Indian maltose and the identification of its structure. The dried crushed root (4.0kg) of Indian lantana was taken and extracted with chloroform in a Sabina extractor. The extract (50 g) was concentrated under reduced pressure and subjected to silica gel G column chromatography using petroleum ether in that order.
