摘 要: GC-MS技术分析丹参地上部分挥发油成分组成。采用超声辅助石油醚提取法提取丹参地上部分挥发油,运用气质联用技术对丹参挥发油进行分析,以面积归一化法计算各化学成分的百分含量。从丹参地上部分挥发油中共检出104种成分,鉴定出59种,其中三萜类化合物4,4,6a,6b,8a,11,12,14b-八甲基-十八氢-2H-亚环庚-3-烯-3-酮(8.950%)、4,4,6a,6b,8a,12,12,14b-八甲基-十八氢-2H-亚环庚-3-烯-3-酮(3.847%)、齐墩果酸(1.909%)、鲨烯(1.695%)和Ursa-9(11),12-dien-3-one(1.622%)为首次从丹参挥发性成分中检出。超声辅助石油醚提取丹参地上部分挥发油组成与已有文献报道差异较大,为丹参挥发油的药理活性探究提供参考依据。

Abstract: Essential oil constituents from aerial parts of Salvia miltiorrhiza Bge. were analyzed by GC-MS. The essential oil was first extracted from aerial parts of Salvia miltiorrhiza Bge.by ultrasound-assisted extraction, and then the chemical constituents were analyzed by GC-MS. The percentage of each chemical constituent was calculated by area normalization method. 104 Kinds of compositions were detected from the essential oil of stems leaves and flowers of Salvia Miltiorrhiza Bge.,59 chemical compositions among them were identified.Triterpenoids 4,4,6a,6b,8a,11,12,14b-octamethyl-1,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadec-ahydro-2H-picen-3-one(8.950%), 4,4,6a,6b,8a,12,12,14b-octamethyl-1,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadec-ahydro-2H-
picen-3-one (3.847%), oleanic acid (1.909%), squalene (1.695%) and ursa- 9(11),12-dien-3- one (1.622%) were obtained from the volatile constituents from aerial parts of Salvia miltiorrhiza Bge. for the first time. The chemical composition of essential oil from aerial parts of Salvia miltiorrhiza Bge. obtained by ultrasound-assisted extraction is quite different from the literature data. This study will provide reference for the pharmacological study of essential oil of Salvia miltiorrhiza Bge..

丹参系为唇形科鼠尾草属植物丹參(Salvia miltiorrhiza Bge.) 的干燥根及根茎,是中国中医临床常用中药,具有活血祛瘀、通经止痛、清心除烦等功效,临床上主要用于月经不调、痛经经闭、胸痹心痛和脘腹胁痛等症状[1]。丹参的主要活性成分包括两部分:脂溶性成分和水溶性成分,脂溶性成分主要包括丹参酮ⅡA、隐丹参酮、丹参酮Ⅰ等,具有抗菌、抗炎等药理作用;水溶性酚酸成分主要包括丹参素、丹酚酸B、迷迭香酸等,具有抗凝血、抗血栓形成和细胞保护等作用[2]。传统上,丹参临床用药主要应用其根及根茎,丹参的地上部分不做药用,而已有研究表明丹参地上部分约占全草重量的67%[3],资源丰富,如果能够将其地上部分充分开发利用,将在很大程度上提高丹参资源的开发利用,减少资源浪费。……
