从獐牙菜中分离出一种新的二氢黄酮-吨酮swertlfrancheslde（Ⅰ），从Maprouneaafricana根中分离出一种三萜1β-hydroxyaleuritolicacid3－p－bydroxybenzoate（Ⅱ）及从冰岛农Cetrariaislandica中分离出一种脂肪族原苔甾酸（Protolichesterinicacid，Ⅲ），均被证实是HIV－1逆
A novel flavanone-toxone swertlfrancheslde (I) was isolated from Swertia spp. and a triterpenoid 1β-hydroxyaleuri tollic acid 3-p-bydroxybenzoate (II) was isolated from the roots of Maprouneaafricana and isolated from the Icelandic agricultural Cetraria islandica. An aliphatic bryophytic acid (Protolichesterinic acid, III), both of which are confirmed to be HIV-1 inverse
