Abstract:
To investigate the chemical constituents of hemostatic extract of Pyrola calliantha H. Andres, the extract was subjected to chromatographic separation and purification. Along with some known compounds, a new naphthaquinone derivative was isolated and identified as 2-(1, 4-dihydro-2, 6-dimethyl-1, 4-dioxo-3-naphthalenyl)-3, 4, 5-trihydroxylbenzoic acid by physicochemical and spectroscopic analysis.
