摘要
目的鉴定海南民族药香十亩香原植物品种,分析其化学成分,以期开发药用植物新资源。方法实地采集十亩香原植物,用基源鉴定、性状鉴定法及DNA条形码技术鉴定十亩香原植物品种;经水蒸气蒸馏法提取十亩香挥发油,应用气相色谱-质谱联用(GC-MS)技术分析挥发油成分;用显色法、沉淀法等对十亩香的化学成分进行系统性预试验。结果十亩香的藤本植物形态、性状特征及DNA条形码特征与豆科蝶形花亚科黄檀属植物红果黄檀(Dalbergia tsoi Merr.et Chun)相匹配;十亩香挥发油提取率为0.2%;GC-MS法检出挥发油组分47个,主含榄香素、苯甲醛与甲基丁香酚,三者相对百分含量之和高于50%;十亩香可能含有机酸类、甾体皂苷类、黄酮类、醌类、香豆素类、鞣质及酚类等化学成分。结论海南民族药香十亩香为豆科蝶形花亚科黄檀属植物红果黄檀含树脂的藤茎,化学成分分析结果表明其具有良好的药用开发价值。
Objective To identify the original species of Hainan national medicine Shimuxiang,and analyze the chemical constituents,to exploit new medicinal plant resources.Methods The original plants called“Shimuxiang”were collected in the field,and their species were identified by taxonomic identification,macroscopic identification and DNA barcoding technology.The volatile oil was extracted by steam distillation and analyzed using gas chromatography-mass spectrometry(GC-MS).A systematic pre-test was carried out by a set of conventional methods including color development and precipitation to preliminarily investigate the chemical components.Results The plant nature,the morphological characteristics and DNA barcoding characteristics of the vines of the Shimuxiang matched with those of Dalbergia tsoi Merr.et Chun.The extraction rate of volatile oil was 0.2%,and 47 components of volatile oil were detected by GC-MS,including elemin,benzaldehyde and methyl eugenol,the sum of the relative percentage of the three is greater than 50%.It may also contain organic acids,steroidal saponins,flavonoids,quinones,coumarins,tannins,and phenols.Conclusion Hainan national medicine Shimuxiang is resinous rattan of Dalbergia tsoi Merr.et Chun,which belongs to the genus Dalbergia in Pterygoideae,a subfamily of Leguminosae.Results of the primary chemical composition analysis show that it has good medicinal development value.
