制备方法与用途

概述

贯叶丝桃(Hypericum perforatum L.),又称千层楼、圣·约翰草(St. John's Wort),属于藤黄科丝桃属的多年生草本植物。该植物花及叶片上多腺点,含有多种具有药理作用的成分,是近年来世界最畅销的草药之一。其提取物杏叶提取物之后,也受到了国外厂商的青睐。德国用作抗抑郁药物已有百余年历史。1980年代,Meruelo等人报道了丝桃素和伪金丝桃素具有抗逆转录病毒作用,包括对抗人类免疫缺陷病毒(HIV)。近年来,这种草药还在艾滋病治疗、恶性神经胶质瘤的研究中进行了临床试验。

制备

贯叶连翘原料经过浸泡前处理后,再用醇溶液提取得到含有丝桃素和伪金丝桃素等有效成分的浸提溶剂。随后通过加热蒸馏浓缩浸提溶剂,得到富含有效成分的浸膏,可用于直接干燥制备提取物浸膏粉,也可以进一步分离、制备高纯度的丝桃素和伪金丝桃素

具体方法为:将贯叶连翘原料粉碎后用浸泡进行预处理。然后用醇溶液提取经预处理后的原料以取得含有丝桃素和伪金丝桃素的醇溶液,再分离提取的醇溶液,随后对提取溶剂进行浓缩、干燥,制得提取物浸膏粉,或进一步精制,获得高含量有效成分的提取物

生物活性

Pseudohypericin及其同系物Hypericin是丝桃属植物中主要的羟基咯啉酮类化合物。研究表明,Pseudohypericin具有抗HIV病毒活性。

体外研究

Pseudohypericin显示出抗逆转录病毒活性。

    描述:
    伪金丝桃素sodium hydroxide 作用下, 以 乙醇 为溶剂, 以35 mg的产率得到Isopseudohypericin

    名称:
    Identification of isopseudohypericin, a new phenanthroperylene quinone obtained by the alkaline treatment of pseudohypericin
    摘要:
    At high pH, pseudohypericin from St. John's Wort (Hypericum perforatum) is converted into a single product which has been isolated. LC-MS analysis indicated that the molar mass of this product is identical to that of pseudohypericin. H-1 and C-13 NMR analysis indicated that the compound is a novel phenanthroperylene quinone which we have named isopseudohypericin; it is a cyclic ether which is an isomer of pseudohypericin.
