Monitoring of distributed Schizandra chinensis (Turcz.) Baill in Korea

This study was investigated that quality inspection of distributed Schizandra chinensis (Turcz.) Baill in Korea. To evaluate the quality of these herbal medicines, we carried out TLC pattern analysis, foreign matter in purity, loss on drying, ash, acid-insoluble ash, oil content, dilute ethanol-soluble, water-soluble, ether-soluble extracts and HPLC analysis. As a result, TLC pattern analysis of gomisin A and shizandrin was showed R _f value 0.64 and 0.74, respectively. Foreign matter in purity, loss on drying, ash and acid-insoluble ash were measured by average 1.30% (±1.08), 12.59% (±1.65), 4.08% (±0.67) and 0.53% (±0.15), respectively. Average oil content, dilute ethanol-soluble extract, water-soluble extract and ether-soluble extract were observed by 0.70(±0.07)%, 38.53(±5.92)%, 39.72(±4.91)% and 12.00(±1.65)%, respectively. To measured contents of schizandrin and gomisin A, we were quantitatively analyzed using HPLC. The average contents of schizandrin and gomisin A were detected by 0.60% (±0.02) and 0.12% (±0.004), respectively.
