the antioxidant activity of garlic influenced by its variety and farming practices. The objectives of this study were to determine the phenolic compounds and antioxidant activity of garlic varieties which were marketed in Indonesia. The phenolic compounds were determined with Folin-Ciocalteu and antioxidant activity was examined using 2,2-diphenyl-2-phicrylhydrazyl (DPPH). Ascorbic acid was used as antioxidant references. In this experiment nine garlic varieties from different region in the world, as well as in Indonesia were investigated. Those varietis were Chinese, Egyptian, Indian, Sangga Sembalun (purple), Sangga Sembalun (white), Sangga Nunggal, Lumbu Kuning, Lumbu Hijau, and Ncuna Sambori. The results showed that antioxidant activities of Lumbu hijau, Sangga Sembalun (white) and Ncuna Sambori were among the highest but not different statistically (p<0.05). Moreover, Sangga Sembalun (purple), Lumbu Kuning, Indian and Sangga Nunggal were in the second level and not different statistically (p<0.05), while Chinese and Egyptian varieties were the lowest. Sangga Sembalun (white) variety was further cultivated with different inputs (manure, dolomit, NPK, SP-36, ZA and KCl). Results showed that the antioxidant activities of Sangga Sembalun (white) which cultivated with different inputs were not different statistically (p<0.05). In general, different inputs in farming practices were not changed the antioxidant activities of garlic variety.
