ABSTRACT
Premna microphylla Turcz. is a commonly used traditional Chinese medicine totreatdysentery and appendicitis. Present study is focused to explore antioxidants and other compounds in the Premna microphylla Turcz. stem. Assessment of chemical composition was done with high sensitivity UPLC-LTQ-Orbitrap-MS and for Separation Thermo Hypersil Gold (100 mm × 2.1 mm, 1.9 µm) was used while electrospray ionization (ESI) was used for the mass spectrometry. 18 compounds were identified including Vitexin (1), Schaftoside (2), Vicenin-2 (3), Apigenin-6, 8-di-C-arabinoside (4), Apigenin-7-O-ß-d-glucoside (5), Carnosic acid (6), Apigenin-8-C-ß-d-xylopyranoside (7), Prostratin (8), Aurantio-obtusin-ß-d-glucoside (9), Royleanone (10), 5-hydroxy-7,3',4'-Trimethoxy flavonols (11), 6-Hydroxy-5,6-dehydrosugiol (12), 14-deoxycoleon (13), Arucadiol (14), Obtusinone-B (15), Trehalose (16), Citric acid (17) and Betaine (18). Among these, 6 compounds including (6), (8), (9), (16), (17) and (18) were identified first time within this genus and plant. Study highlights the importance of Premna microphylla Turcz. stem extract for strong therapeutic potential against oxidation-related diseases.
