    • PURPOSE: Provided is a lactone compound obtained from Actinodaphne lancifolia. The compound has apoptosis activity and less toxicity, and is thus useful as therapeutic agents or aids for chronic or incurable diseases including immune system disease and brain disease. CONSTITUTION: A method for obtaining a lactone compound comprises the steps of: extracting pulverized Actinodaphne lancifolia with a mixture of methanol and water; fractionating with hexane and ethylacetate to give hexane and ethylacetate fractions; subjecting the hexane fraction to absorption chromatography; and obtaining isolancifolide, lancifolide and actinolide B of the formula(1-3) from the hexane-ethylacetate fraction.
    • 目的:提供从Actinodaphne lancifolia获得的内酯化合物。 该化合物具有凋亡活性和较低的毒性,因此可用作治疗剂或用于慢性或不治之症(包括免疫系统疾病和脑部疾病)的辅助剂。 构成:获得内酯化合物的方法包括以下步骤:用甲醇和水的混合物提取粉碎的放线菌素; 用己烷和乙酸乙酯分馏,得到己烷和乙酸乙酯级分; 使己烷部分进行吸收色谱; 并从己烷 - 乙酸乙酯部分中获得式(1-3)的间苯三酚,兰可夫酸和锕系元素B。
