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\u0027 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", "download_preview_message": "", "file_order": 0, "filename": "Hnin Hnin Ei (283 to 290).pdf", "filesize": [{"value": "368 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 368000.0, "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.
