生产方法
从泰国大戟科巴豆属植物Croton sulblyratus Kurz的茎叶中(商品为Plaunoi)提取的有效成分。81.5kg商品Hau-noi经粉碎,用丙酮回流提取3次。提取液浓缩后,剩余物溶于10L80%甲醇水溶液,用n-己烷洗。甲醇层经浓缩后,在剧烈搅拌下倾入40L苯。苯溶液经浓缩后,剩余物用乙醚提取。乙醚溶液用3kg硅胶柱层析,苯和乙酸乙酯洗脱,得53g普劳诺托。上述经乙醚提取后的不溶物,用5kg硅胶层析,氯仿和甲醇洗脱,可得到12gFuranoditerpeneA[熔点180~181℃,[α]D20-142°(C=1.0,丙酮)]和28gFuranoditerpeneB[熔点170~172℃,[α]D20-144°(C=1.0,丙酮)],它们和普劳诺托的活性相同。同样对普劳诺托的全合成做了尝试。
用途
防御因子增强型抗溃疡药。用于胃溃疡。
