笔者从黄柏(Phellodendri Cortex)中提取小檗碱类生物碱以外的成分,研究对各种实验性溃疡及对胃液分泌作用的效果。实验方法:将黄柏用甲醇加热提取,过滤。残渣用同法反复进行提取,除去甲醇可溶性成分(小檗碱类生物碱等),其残渣干燥后用50％乙腈室温下提取数次。提取液除去溶媒,将其中水溶性部分(收率2.0％)用于实验。将 The authors extracted ingredients other than berberine alkaloids from Phellodendri Cortex to study the effects of various experimental ulcers and gastric secretion. Experimental method: The cork was extracted with methanol and filtered. The residue was repeatedly extracted by the same method to remove methanol-soluble components (berberine alkaloids, etc.), and the residue was dried and extracted several times with 50% acetonitrile at room temperature. The solvent was removed from the extract and the water soluble fraction (yield 2.0%) was used for the experiment. will
