摘要
以市售五个普通茶叶样品为对照,采用薄层色谱分离白毛茶的多种生物嘌呤碱。以乙酸乙酯:丙酮:氨水=4:3:1(V:V)为流动相,硅胶G为固定相,展开浸取后,用紫外分光光度法在273nm处测定其成分含量。结果表明:南昆山白毛茶具有特殊性,其生物碱种类及成分结构异于普通茶叶,含有丰富的可可碱,高达3.02～3.15%,比普通对照样高出11.7～13.2倍。总生物碱量为4.68～4.89%。
with five sorts of common tea from market as comparison, with the color atlas of thin layer split the various biology of Baimao ea Piao Ling soda, with Yi acid Yi ester: Third ketone: Ammonia water = 4: 3: 1( V: V ) to flow appearance, silica gel G is stationary phase, spread out to soak take after, survey its composition content with the ultraviolet photometry of beam splitter in the place of 273 nm. Show as a result: Nankunmountain Baimao tea have particularity, its alkaloid kind and structural content are more different than ordinary tea , it contains plenty of the heobromine, Content range 3.02%～3 .15%,it is 11.7～13.5 times higher than CK. Its total alkaloid number is 4.68～4.89%.
