Abstract:
Free radicals may be created by internal factors and external factors. It damages cellular
components and leads to develop of diseases. Vitamin A C E or beta-carotene as well as Polyphenols
compounds which are Phytochemical and can be found in plants, these can be used for helping to fight
against the oxidation reaction in the body more effectively and eliminate the free radicals. Therefore,
a study about level of antioxidant in 6 herbs have been created, there were Purple glutinous rice,
Mulberry (Morusalba Linn.),Five-leaf ginseng (Gynostemmapentaphyllum Makino.), Artichoke
(Cynarascolymus L.), Moringa (Moringaoleifera Lam.) and Green tea (Camellia sinensis). DPPH was
used as method of measuring the amount of antioxidant. The results of percentage DPPH radical
scavenging of Green tea 87.066%, Artichoke 76.902%, Moringa 66.195%, Five-leaf ginseng
60.194%, Mulberry 30.101% and Purple glutinous rice 19.710% respectively. Furthermore, the results
of comparison antioxidant level among 6 herbs by One-Way ANOVA showed statistically significant
difference p <0.001amount of antioxidant in 6 herbs at 95% confidence level. Thus, the 6 herbs have
different antioxidant potentials to fight against the free radicals can be concluded from this study.
