伏砖砖茶是以茶树品种茶树(Camellia sinensis var.)通过微生物发酵法生产冬虫夏草。从这种特殊的发酵茶中,分离出一种新的降类异戊二烯,即3R,9 R-氧化-5-巨甾烯,以及α-亚麻酸、strictin、异牡荆苷、黄芪苷、(+)-儿茶素、(-)-表儿茶素、(-)-表儿茶素没食子酸酯、(+)-没食子儿茶素、(-)-表没食子儿茶素、(-)-表没食子儿茶素没食子酸酯和没食子酸。化合物的结构经波谱方法鉴定。用孔板扩散法测得新化合物在800 μg/mL浓度下对供试肠道病原微生物无抑制作用。
Fuzhuan brick tea, a kind of dark tea consumed mainly in the border regions of Southwestern and Northwestern China since the 1860s, is produced from the leaves of Camellia sinensis var. sinensis by microbial fermentation. From this special fermented tea, a new norisoprenoid, 3R,9R-oxido-5-megastigmene, was isolated, together with α-linolenic acid, strictin, isovitexin, astragalin, (+)-catechin, (−)-epicatechin, (−)-epicatechin gallate, (+)-gallocatechin, (−)-epigallocatechin, (−)-epigallocatechin gallate and gallic acid. The structures of the compounds were identified by spectroscopic means. The new compound didn’t show any inhibition activity against the tested enteric pathogenic microorganisms at a concentration of 800 μg/mL by the hole plate diffusion method.
