目的分析狭叶羌活(Notopterygium incisumTing ex H. T. Chang)根茎和根的挥发油的化学成分,为其质量评价提供科学依据。方法采用水蒸气蒸馏法提取狭叶羌活根茎和根的挥发油,用GC毛细管柱进行分析,归一化法测定其相对含量,并用GC-MS法鉴定化学成分。结果检出242个色谱峰,初步鉴定出83个化合物,占挥发油总量的75·77%。结论狭叶羌活根茎和根的挥发油中的化学成分主要为单萜和倍半萜类化合物,两者分别占总油中化学成分的13·63 %和67.93 %。(1S)-β-蒎烯(1·67%)、3-蒈烯(1·05%)、柠檬烯(1·22%)和1S-endo-醋酸冰片酯(1·68%)为单萜类化合物中的主要成分;( +)-β-榄香烯(6·78%)、苜蓿烯(1·54%)、α-石竹烯(2·64%)、异大香叶烯D (1·67%)、桉烷-4 (14),11-二烯(2·36%)、α-芹子烯(2·42%)、δ-杜松烯(1·55%)、3,7,11-三甲基-2,6,10-十二烷三烯-1-醇(1·03%)、(±)-榄香烯(5·18)、(-)-匙叶桉油烯醇(1·40%)、愈创醇(3·81%)、去羟基异菖蒲烯二醇(1·06%)、γ-桉醇(1·05%)、α-桉醇(7·97%)、异愈创木醇(3·09%)和胡萝卜醇(2·30%)为倍半萜类化合物中的主要成分。总挥发油中,反式肉桂酸异丙酯占11·3%,为所有化合物中含量最高者。
Objective To analyze the chemical constituents of the volatile oil from roots and roots of Notopterygium incisum Ting ex H. T. Chang and provide scientific basis for its quality evaluation. Methods The volatile oil from the rhizomes and roots of N. crassifolia was extracted by steam distillation and analyzed by GC capillary column. The relative contents were determined by the normalized method. The chemical components were identified by GC-MS. As a result, 242 peaks were detected and 83 compounds were initially identified, accounting for 75.77% of the total volatile oil. Conclusion The chemical constituents in the volatile oil from rhizomes and roots of N. crassifolia are mainly monoterpenes and sesquiterpenoids, which account for 13.63% and 67.93% of the total oil. (1S)-β-pinene (1.67%), 3-decene (1.05%), limonene (1.22%) and 1S-endo-bornyl acetate (1.68%) are monoterpenes. (+)-β-elemene (6.88%), nonene (15.44%), α-caryophyllene (2.64%), allosterone D ( 1.67%), decane-4 (14), 11-diene (2.36%), α-selinene (2.42%), δ-durene (1.55%), 3 ,7,11-trimethyl-2,6,10-dodecatrien-1-ol (1.03%), (±)-elemene (5.18), (-)-key Terpene enol (1·40%), Guaiacol (3.81%), dehydroxyisodecyldiol (1·06%), γ-sterol (1·05%), α-sterol (7.97%), isoguaiacol (3.09%), and carotenol (2.3%) were the main components in the sesquiterpenes. In the total volatile oil, trans-isopropyl cinnamate accounted for 11.3% of the total content of all compounds.
