Oxidative stress induces various diseases. Some of them, Arabian jasmine, Guava, Hardy rubber tree, Japanese per-simmon, Oolong tea and Puerh tea, have high total polyphenol content and antioxidant activities. Herbs and herbal polyphenols pay in controlling oxidation and prevent the damage by oxidation. These results showed that some of them, Arabian jasmine, Guava, Hardy rubber tree, Japanese persimmon, Oolong tea and Puerh tea, have high total polyphenol content and antioxidant activities. It has been demonstrated that high total polyphenol content in the herb teas provides high antioxidant activities.展开更多
