    Phytochemical analysis and antioxidant potential of the leaves of Garcinia travancorica Bedd.[Pubmed: 25982126 ]

    METHODS AND RESULTS:
    Phytochemical analysis of the leaves of Garcinia travancorica, a hitherto uninvestigated endemic species to the Western Ghats of south India, resulted in isolation and characterisation of the polyisoprenylated benzophenones 7-epi-nemorosone (1) and garcinol (2) along with biflavonoids GB 1a (3), GB-1 (4), GB-2 (5), morelloflavone (6) and morelloflavone-7″-O-β-D-glycoside or fukugiside (7). The compounds were identified using various spectroscopic techniques, mainly through NMR and MS. The methanol extract and the biflavonoids 3, 4, 5 and 7 showed potential in vitro antioxidant activities. The IC50 value of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of compound 7 was 8.34 ± 2.12 μg/mL, comparable to that of standard ascorbic acid (3.2 ± 0.50 μg/mL). In the superoxide radical scavenging assay, compound 7 gave IC50 value of 6.95 ± 1.33 μg/mL close to standard ascorbic acid with IC50 value of 5.8 ± 0.25 μg/mL.
    CONCLUSIONS:
    Validated HPTLC estimation revealed G. travancorica as a rich source of morelloflavone-7″-O-β-D-glycoside (7.12% dry wt. leaves).
