| Abstract |
Many studies have been conducted on the bioactive compounds of rice seeds, however,
there is limited information on the bioactive compounds of rice sprouts. This study focused on
the age effect on the phytochemical content of white and black glutinous rice sprouts harvested
between 5 and 25 days old. We assessed yield, total phenolic content, total flavonoid content, total
anthocyanin content, total chlorophyll content, and proximate analysis. HPLC results identified
protocatechuic acid, vanillic acid, and rutin in the sprouts of both cultivars, ranging between
0.56–1.58, 0.65–7.69, and 0.47–1.68 mg/g extract, respectively. The amount of bioactive compounds
and proximate compositions in black glutinous rice were generally higher than white glutinous rice
in an age-dependent manner (p < 0.05). At 5–7 days, black glutinous rice contained the highest total
anthocyanin content, while white glutinous rice contained the highest total phenolic content and total
flavonoid content (p < 0.05). High total chlorophyll content was initially detected in white glutinous
rice at a younger age than black glutinous rice (p < 0.05), while total chlorophyll content in both
cultivars was not significantly different. Our study confirms the presence of phytoconstituents in the
rice sprouts of white and black glutinous rice and their potential as functional foods and for being
further development as natural health products. |
