Hydrolysates of infusions of green tea and black tea were mutagenic by the Ames test. The tea infusions were prepared by a regular method and were hydrolysed with 1 M HCl, hesperidinase, naringinase and human intestinal bacteria. The hydrolysates were successively extracted with chloroform, diethyl ether and ethyl acetate. The mutagenicities of the extracts were assayed by the Ames test, and the mutagens were analysed by GC-MS. The ether extracts of the hydrolysates of infusions of both green… CONTINUE READING
