摘 要 目的 建立竹節(jié)蓼藥材的高效液相色譜(HPLC)指紋圖譜,并進行聚類分析。方法:采用HPLC法。色譜柱為Ultimate C18,流動相為乙腈-0.1%磷酸溶液(梯度洗脫),流速為0.5 mL/min,檢測波長為360 nm,柱溫為28 ℃,進樣量為10 μL。以槲皮苷為參照,繪制13批藥材樣品的HPLC圖譜,采用《中藥色譜指紋圖譜相似度評價系統(tǒng)》(2012版)進行相似度評價,確定共有峰,并對其進行聚類分析。結果:13批藥材樣品的HPLC圖譜有12個共有峰,相似度均大于0.90;經(jīng)驗證,13批藥材樣品的HPLC圖譜與對照指紋圖譜具有較好的一致性。13批藥材樣品可聚為兩大類,S4、S6、S10聚為一類,其余聚為一類。結論:該研究所建指紋圖譜和聚類分析結果可為竹節(jié)蓼藥材的質量評價及進一步開發(fā)利用提供參考。

ABSTRACT OBJECTIVE: To establish HPLC fingerprint of Homalocladium platycladum, and to carry on the cluster analysis. METHODS: HPLC method was adopted. The determination was performed on Ultimate C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (gradient elution) at the flow rate of 0.5 mL/min. The detection wavelength was set at 360 nm, and column temperature was 28 ℃. The sample size was 10 μL. Using quercetin as reference substance, HPLC chromatograms of 13 batches of samples were determined. The similarity evaluation was carried out by using Similarity Evaluation System for TCM Chromatographic Fingerprint (2012 edition) to determine common peak. Cluster analysis were also conducted. RESULTS: A total of 12 common peaks were established in HPLC fingerprints of 13 batches of samples. The similarity was higher than 0.90. After validation, HPLC chromatograms of 13 batches of sample were in good agreement with control fingerprint. 13 batches of medicinal materials were clustered into 2 categories; S4, S6 and S10 were clustered into one category, and the rest were a category. CONCLUSIONS: Established fingerprint and cluster analysis results can provide reference for quality evaluation of H. platycladum and its exploitation and utilization.

竹節(jié)蓼又名觀音竹、飛天蜈蚣、扁竹[1-2],其味甘、淡,性平,歸肝、肺經(jīng),具有清熱解毒、去瘀消腫之功效,主治癰瘡腫毒、跌打損傷等癥[3]。壯醫(yī)認為其味甘、酸,性微寒,具有清熱解毒、活血止血的功效,臨床主要用于扁桃體炎、支氣管炎、尿路炎癥及崩漏帶下、癰瘡腫毒、跌打損傷、蛇蟲咬傷等病癥的治療[4]。目前,竹節(jié)蓼的研究主要集中在抗腫瘤[5-7]、抗菌[8-9]作用和活性組分等方面,而在質量評價方面研究較少。本課題組前期已通過高效液相色譜法(HPLC)測定了其中槲皮苷的含量[10],在此基礎上,本試驗采用HPLC法對廣西5個不同產(chǎn)地13批竹節(jié)蓼藥材展開指紋圖譜研究,并進行聚類分析,以期為其質量評價及進一步開發(fā)利用提供參考。
