Abstract The whole plant of Swertia hookeri , collected at flowering has been shown to contain two tri- and nine tetraoxygenated free, glucosyloxy, and stearyl ester xanthones and one flavonol stearyl ester. Among these, three are previously unreported in nature and one was known previously only as a synthetic compound. The xanthones are based on 1,3,5,-, 1,3,5,8- and 1,3,7,8-oxygenated systems with
摘要 在开花时收集的虎尾草全株已被证明含有两种三和九四氧化的游离、葡糖氧基和硬脂酰氧杂蒽酮以及一种黄酮醇硬脂酰酯。其中,三种以前在自然界中未报道过,一种以前仅作为合成化合物已知。氧杂蒽酮基于 1,3,5,-, 1,3,5,8- 和 1,3,7,8- 氧化系统,中间氧化模式占主导地位。这两种酯类化合物只出现在开花期。在开花前阶段收集的植物产生相应的游离化合物。评估了这些发现的生化和生物学意义。
