摘要

背景:山梨树(Litsea chinensis)是一种中等大小的树木,其心材在阿育吠陀医学中被广泛用于治疗各种疾病。该物种在野外的数量正在减少,将来可能很难在阿育吠陀和其他传统医学体系中获得该物种。它的主要用途是药用心材。因此,使用这种植物的替代部分来代替它的心材将有利于它的生存。目的:对羊草进行植物化学研究,评价其小枝替代其心材的可能性。材料与方法:采用标准方法进行理化参数和初步植物化学筛选。分光光度法测定总酚和总黄酮含量,分别采用福林-ciocalteu法和氯化铝法测定。采用CAMAG HPTLC系统,配备半自动涂布器进行HPTLC分析。正己烷、乙酸乙酯和乙醇提取心材和小枝,在合适的流动相中采用标准程序制备,用茴香醛-硫酸试剂衍生化后,在254,366nm和白光下观察。结果:心材和小枝不同提取物的植物化学分析和HPTLC图谱显示,在该植物的两个部位中,存在几乎相似的植物化学物质,通过比较和确认药理活性相同,提示小枝可以代替心材,反之也可以。结论:本研究为进一步研究利用羊草小枝替代其心材提供了基础。

Plant part substitution in Litsea Chinensis for medicinal use: A comparative phytochemical approach
Background: Medasakha (Litsea chinensis) is a medium sized tree, heartwood of which is extensively used in Ayurveda for the treatment of various diseases. Count of this species is declining in the wild and in future this species may be difficult to obtain for use in Ayurveda and other traditional systems of medicine. It is exploited mainly for its medicinal heartwood. Hence the use of alternative parts of this plant in place of its heartwood would be beneficial for its survival. Objective: Present study is carried out on L. chinensis to phytochemically evaluate the possibilities of using its small branches as a substitute to its heartwood. Materials and Methods: Physicochemical parameters and preliminary phytochemical screening were carried out using standard methods. Total phenolic and total flavonoid contents were estimated spectrophotometrically using Folin-ciocalteu and aluminum chloride method, respectively. CAMAG HPTLC system equipped with semi-automatic applicator was used for HPTLC profiling. n-Hexane, ethyl acetate and ethanol extracts of heartwood and small braches were developed in suitable mobile phase using standard procedures and visualized in UV 254, 366 nm and in white light after derivatization with anisaldehyde-sulphuric acid reagent. Results: Phytochemical analysis and HPTLC profile of different extracts of heartwood and small branches showed the presence of almost similar phytochemicals in both the parts of this plant which suggests that small branches may be used in place of heartwood and vice-versa after comparison and confirmation of same for pharmacological activities. Conclusion: This study provides the base for further study to use small branches of L. chinensis as a substitute to its heartwood.
