摘　　要：目的:建立辽东楤木叶总皂苷高效薄层色谱指纹图谱,并分析不同产地不同采收期的辽东楤木叶成分的差别。方法:采用高效硅胶G薄层板(20 cm×20 cm)载样,以三氯甲烷-甲醇-乙酸乙酯-甲酸-水(9. 5∶10∶20∶0. 5∶5)为展开剂,以10%浓硫酸乙醇溶液为显色剂,于恒温鼓风干燥箱里100℃条件下加热至斑点清晰,置于365 nm紫外光下照射获得其显色后的荧光高效薄层色谱图,经软件组合处理生成斑点灰度峰曲线,建立共有模式,并进行相似度分析及聚类分析。结果:获得分离度良好、斑点清晰的高效薄层色谱指纹图谱,建立了辽东楤木叶总皂苷薄层色谱指纹图谱共有模式,由10个共有斑点峰组成,并指认了其中的4个斑点峰代表的具体成分。分析表明不同地区8月初至9月中旬的辽东楤木叶相似度较高;聚类分析将11个不同批次的样品聚为一大类。结论:建立的薄层色谱指纹图谱方法简单、快速、可靠,可用于辽东楤木叶药材的鉴定和质量控制评价。确定东北地区8月采收的辽东楤木叶药材均符合质量要求,可作为以总皂苷为主要药效部位的药材使用。Objective: To establish high performance thin layer chromatography( HPTLC) fingerprint of the total saponins from Aralia elata leaves,and compare the difference of components in A. elata leaves from different harvest time and different regions. Method: High efficiency silica gel G thin sheet( 20 cm × 20 cm) was used,with chloroform-methanol-ethyl acetate-water( 9. 5 ∶ 10 ∶ 20 ∶ 0. 5 ∶ 5) as developing system,ethanol solution of 10% concentrated sulfuric acid as chromogenic reagent,heating at 100 ℃ in constant-temperature air dry oven until clear spots. The fluorescence HPTLC chromatogram fingerprints were obtained under 365 nm ultraviolet light.Speckle patterns were obtained by software processing and the common pattern was established for similarity analysis and cluster analysis. Result: The HPTLC fingerprints with good separation and clear spots were obtained and the common pattern of fingerprints was established. The common pattern was composed of 10 common speckled peaks,4 of which were identified for components. The results showed that samples in early August to mid September from different regions had good similarity. 11 samples of different batches were clustered into one class. Conclusion:The HPTLC method is simple,fast and reliable,and can be used for the identification and quality evaluation of medicinal materials of A. elata leaves. The A. elata leaves collected in August conform to the quality standard,so they can be used as medicinal materials.
