The fingerprint information of Bupleurum at five wavelengths (210, 254, 265, 280 and 320 nm) collected by HPLC-DAD instrument was fused to overall control its quality. The fusion fingerprints and four components (saikosaponin a, saikosaponin d, rutin, quercitrin) were studied by systematic quantitative fingerprint method and principal component analysis, respectively. Besides, fingerprint-efficacy relationship was constructed in vitro using partial least-squares model. In conclusion, all work can serve as a valid reference for the quality control of Bupleurum .展开更多

The results showed that the germination rate of fresh water at 12 h was significantly higher than that at 8 h and 36 h; The germination rate of seeds treated with constant temperature 15℃ and variable temperature 25 ℃/15 ℃ （day/night） was significantly higher than that of other temperature treatments. Seed soaking time and culture temperature also influenced seed germination start day and peak day. Different concentrations of regulatory substances could promote seeds germination. The germination rate of seeds induced by 0.50 mg/L 6-BA was the highest, the start day and peak day were 4 days and 5 days earlier than control check （CK） respectively.展开更多
