1-hydroxydihydropanaxacol (3) and 17-hydroxypanaxacol (4), were isolated from Panax ginseng hairy root culture, along with dihydropanaxacol (1), panaxacol (2) and ginsenoyne D (5). Highly hydroxylated compounds 1-4 were isolated from the medium and compound 5, which was a biosynthetic precursor of compound 1, was isolated from the roots. Compounds 1-4 showed antimicrobial activity against Staphylococcus aureus,
从人参毛状根培养物中分离出两种新的聚乙炔,1-羟基二氢人参三醇(3)和17-羟基人参三醇(4),以及二氢人参三醇(1),人参三醇(2)和人参炔D(5)。从培养基中分离出高度羟基化的化合物1-4,并从根中分离出化合物5(其为化合物1的生物合成前体)。化合物1-4显示出对金黄色葡萄球菌,枯草芽孢杆菌,新隐球菌和烟曲霉的抗菌活性。建议人参植物从根部向周围土壤释放抗菌聚乙炔作为防御化合物。
