Objective: To determine the concentration of schisandrin in Shengmaiyin with HPLC.
Method: The sample was extracted with ethyl acetate through supersonic wave. The solution was filtrated and evaporated. The residue was resolved with methanol and determined by HPLC using PHENOMENEX C18 (4.6 mm x 250 mm, 5 microns) chromatographic column, methanol-acetonitrile-water (15:15:10) as mobile phase. The wavelength for detection was 254 nm.
Result: The peak of schizandrin appears on about 7.10 minutes. The standard curves of schizandrin were linear in the concentration range of 0.2-2.0 micrograms, r = 0.9996. The average recovery of schizandrin were 100.5% (RSD 2.84%).
Conclusion: This method was found to be sensitive, quick and accurate for the measurement of schizandrin concentrations in Shengmaiyin.

Ethnopharmacological Relevance: Ginseng Radix et Rhizoma (GRR) and Schisandrae Chinensis Fructus (SCF) are frequently used as herb pairs in traditional herbal formulas especially for the synergetic beneficial effects on lung and heart. Shengmai-yin (SMY), a noted formula, was first published in the traditional Chinese medicine classic named Yixue Qiyuan written by Zhang Yuansu in the Jin Dynasty, and has been used for deficiency of both qi and yin, palpitation, shortness of breath and spontaneous sweating. In SMY, GRR, a sovereign herb, plays an essential role in tonifying lung and supplementing qi, and SCF as an adjuvant herb contributes to the effects of nourishing yin and promoting fluid production, both of which are traditionally used as invigorants in China, Korea, Japan, and Russia.

Shengmaisan (SMS) is a famous traditional Chinese medicine (TCM) formula to treat coronary heart diseases. It has been developed into several TCM patent drugs to meet the demands of different patients. In this study, a research strategy was proposed to reveal the chemical variations among four SMS-based patent drugs, including Shengmai Oral Solution (Shengmaiyin, SMY), Shengmai Capsule (Shengmai Jiaonang, SMJN), Yiqi Fumai Injection (YQFMI), and Yiqi Fumai Capsule (Yiqi Fumai Jiaonang, YQJN).
