In this study, we determined that the antimutagenic properties of various tea extracts including green, oolong, pu-erh tea, and black tea and six polyphenols include rutin, quercetin, apigenin, gallic acid, umbelliferone, and tannic acid were examined by Ames test which is a widely applied short-term bacterial assay for detecting DNA damage effect of mutagen.

在本篇研究中，我們探討利用Ames test的方法篩檢不同品種茶類包括綠茶日韩手机自拍无码专区、烏龍茶经典18岁黄片、普洱茶、紅茶和數種常見的多酚類化合物包括單寧酸t(yī)annic acid操屄无码、gallic acid黄色免费的网址、rutin、umbelliferone欧美丰满熟妇性XXXX、apigenin国产美女人人操、quercetin對於抑制PhIP（2-amino-1-methyl-6-phenylimidazo(4，5-b)pyridine）和 2-AAF（2-Acetylaminofluorene）兩種致突變劑的抗突變作用麻豆高中生第一次破处。

But both 20 years and 2 years old of pu-erh tea extracts show a strong inhibitory effects against 2-AAF. In addition, tannic acid, gallic acid, rutin, umbelliferone, and quercetin exhibited stronger antimutagenicities against PhIP than apigenin; while all of these polyphenols displayed inhibitory effect against 2-AAF.

The detected phenolic, gallic acid was gradually increased with continuous cropping years increasing, vanillic was steady in soil of different continupus cropping years, ferulic acids had more content in soil of five-year continuous cotton cropping, but remarkably reduced with ten-year continuous cropping.7 It was found that the p-hydrobenzoic, vanillic, gallic acid and ferulic acids in different comentration inhibited/stimulated the spore germination and mycelium growth of cotton verticillium wilt.

Alkyl gallates can also low the extent of lipid peroxidation. To investigate the effects of PG and AG on livers that were injured by tetrachloride, we treamed small mice and fed them with different medicines, The conclusion is that AG and PG could scavenge free radical and protect mice livers from injuring by tetrachloride, AG was more effective than PG. 4. 3 The results of experiment for scavenging free radical of alkyl gallate in vitro showed that alkyl gallates can effectively scavenging free radical, but the parent gallic acid showed little effect. This suggested that introducing of hydrophobic group could significantly improve the anti-oxidative ability of gallic acid derivatives at large extent.
