HPLC Method for the Simultaneous Determination of three Lignans of Schisandra sphenanthera Collected in Ngoc Linh Mountain, Kon Tum Province, Vietnam
A simple and sensitive high performance liquid chromatography (HPLC-DAD) method for simultaneous quantification of schisandrin, gomisin B, schisandrin A in the ripe fruit of Schisandra sphenanthera was developed and validated. The chromatographic separations were obtained by an Agilent C18 column (250 x 4.6 mm i.d., 5 µm particle size) using gradient elution with acetonitrile and water, at a flow rate of 0.8 mL/min and detection wavelength at 254 nm. All calibration curves displayed a good linear relationship (R2=0.999). The validation results displayed good accuracy, repeatability, linearity, and selectivity according to the ICH guideline. The established method was applied to analyze 6 samples collected Ngoc Linh mountain (Kon Tum, Vietnam). The contents of schisandrin, gomisin B, schisandrin A in Schisandra sphenanthera samples collected in Ngoc Linh mountain were 0.197-0.246%, 0.207-0.275%, and 0.107- 0.132%, respectively. The obtained results provided useful information for the quality testing of the fruit of Schisandra sphenanthera in Vietnam.
