| Abstract | Mae Phaya Tong Dum rice is the local black rice of Chanthaburi province, Thailand. This rice has the purple-black pigments presented in the rice bran. Black rice has reported that there is a good source of several bioactive compounds. This research emphasized the comparing of the antioxidant and anti-acetyl cholinesterase activities of unrefined black rice (UBR) and parboiled germinated unrefined black rice (PGUBR) extracts of Mae Phaya Tong Dum rice. The results found that UBR extracts obtained higher antioxidant and enzyme inhibitory activities than that of PGUBR extracts. The methanol extracted of UBR showed the highest antioxidant activity (IC50 = 217 ยตg/ml) and total phenolic content (469.716 ยตgGAE/g) more than that of methanol extracts of PGUBR (IC50 = 534 ยตg/ml and 334.489 ยตgGAE/g, respectively). Whereas hexane extracts were the best enzyme inhibitor, UBR had higher inhibition than PGUBR (IC50 = 58 and 181 ยตg/ml respectively). Using heat in the process of PGUBR from the Mae Phaya Thong Dam variety resulted in a decrease in the bioactivity of the black rice seed extract. Therefore, in the process of Germinated hang rice, it should be considered the heat used. |
