Bagasse Extracts}, volume={8}, url={https://li02.tci-thaijo.org/index.php/ssstj/article/view/217}, abstractNote={<p>The aim of this work was to screen the phenolic compounds and antioxidant activity of sugarcane ( Saccharum officinarum L. ) bagasse extracts. The selected sugarcane bagasse was cultivated in Maha Sarakham province. Suphanburi 50 (SP50) and 72 (SP72) and Authong 17 (AU17) cultivars were extracted with methanol and solvent evaporated using a rotary evaporator. The methanolic crude extracts were then analyzed for total phenolic (TPC), flavonoid (TFC), saponin (TSC), condensed tannin (TCT), and proanthocyanidin (TPAC) content. It was found that AU17 extract had the highest content of phytochemicals. The AU17 extract also has the highest antioxidant activities, when studied by free radical (ABTS, DPPH) scavenging activity and metal- (FRAP, CUPRAC) reducing power. TPC was positively correlated to DPPH, FRAP, and CUPRAC than that of ABTS, while TFC showed a high correlation using all the tested methods for antioxidant activity. Using HPLC, AU17 bagasse extract showed higher phytochemical contents than SP strains. The dominant substances in the sugarcane extracts were gallic acid, pcoumaric acid, caffeic acid, quercetin, and epicatechin. The results suggested that sugarcane bagasse is a potential source of natural phytochemicals and might be of use as a source of substances for health benefits.</p>}, number={2}, journal={Suan Sunandha Science and Technology Journal}, author={Srihanam, Prasong and Thonpho, Ansaya and Sanarat, Panadda and Motham, Phongsathorn}, year={2022}, month={Nov.}, pages={26–35} }
