摘要
从湘西抗菌草药柄叶香茶菜（Rabdosiaphyllopodia）中分得2个二萜化合物，经鉴定为卢氏冬凌草素5（ludondnin5）和贵州冬凌草素1（guidongnin1）．前者在2．5～30μg／mL时对大肠杆菌、溶血性链球菌、金黄色葡萄球菌、卡他杆菌、伤寒杆菌、痢疾杆菌、变形杆菌有抑菌作用．
Two known diterpenes, ludongnin 5 and guidongnin 1 were isolated from alcoholic extracts of Rabdosia phyllopodia (Labiatae)by silica gel columm chromatography, Alcohoilc extracts and ludongnin 5 possess antibacterial activities. Ludongnin 5 exist bacteriostasis(2. 5~30μg/mL)to E. coli. Streptococcus bata, S. aureus,Catarrhus, S. typhi, Shigella spp. and Proteus.
