Abstract:
OBJECTIVETo investigate the chemical constituents and establish a quantitative method of Mallotus apelta.
METHODCompound was isolated by silica gel, Sephadex LH-20 column chromatography and Pre-HPLC chromatography. Its structure was identified by physicochemical properties and spectral evidences. The content of M. apelta was determined by HPLC. Chromatographic conditions included Inertsil ODS-3 C18 column (4.6 mm x 150 mm, 5 microm) and the mobile phase consisting of a mixture of methanol-water (24:76). The detection wavelength was set at 335 nm.
RESULTOne compound was isolated from n-butanol extract of the M. apelta and its structure was identified as vicenin II. The calibration cure was linear in the range of 0.053-10.60 microg (r = 0.9999), the average recovery was 99. 32%, RSD 1.82% (n = 6).
CONCLUSIONThe compound was isolated from this plant for the first time. The method to determine the content of vicenin II by HPLC was established for the first time. This method is simple, accurate and reliable.
