The Folin-Ciocalteu reagent (FCR) method was used to measure the total phenolic contents of the ethanol and watery extracts of S. burkillii tuber, and the results showed 135.46 g GAE/mg and 35.75 g GAE/mg, respectively. The DPPH free radical scavenging experiment was used to test the antioxidant activity, and the results revealed that both the ethanol extract (IC50 42.54 g/mL) and the watery extract (IC50 50.32 g/mL) exhibited moderate antioxidant activity when compared to the standard ascorbic acid (IC50 1.74 g/mL). By utilizing column chromatography, an organic compound called stigmasterol (41 mg, 0.014%) was extracted from S. burkillii tubers' alkaloid-free ethyl acetate extract. It was then identified by FT IR spectroscopy, and its spectra were compared to those previously reported for stigmasterol."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"S. burkillii tubers"},{"interim":"total phenol content"},{"interim":"antioxidant activity"},{"interim":"column chromatography"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-02-12"}],"displaytype":"preview","filename":"Hnin Hnin Ei (283 to 290).pdf","filesize":[{"value":"368 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/9300/files/Hnin Hnin Ei (283 to 290).pdf"},"version_id":"33d1fc5d-6c98-4309-b6f8-634b9b9cbbeb"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"2022","subitem_journal_title":"University of Yangon Research Journal","subitem_pages":"283-290","subitem_volume":"11, No. 1"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Hnin Hnin Ei"},{"subitem_authors_fullname":"Mya Thandar Aung"},{"subitem_authors_fullname":"Saw Hla Myint"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2022-12-31"},"item_title":"Investigation of Antioxidant Activity and Isolation of an Organic Compound from Tubers of Stemona burkillii PRAIN.
