摘要
用水蒸气蒸馏法提取天麻次生块茎(箭麻)的挥发性成分,用气相色谱质谱法(GC-MS)对化学成分进行分离鉴定,并用面积归一化计算各成分相对含量.结果显示:红天麻中共有42个成分,其中已知成分有14种,占总量的63.189%;绿天麻共有48个成份,已确定成分的有29种,占总量的84.313%.红天麻中的主要成分是2,3,5,6-四甲基吡嗪(25.331%),2-戊基呋喃(11.974%)和E,E-2,4-癸二烯醛(8.66%).绿天麻挥发油的主要成分是亚油酸乙酯(15.444%),苯乙烯(10.352%)和棕榈酸乙酯(10.066%).比较两种天麻的挥发油成分,有8种共有成分,这些共有成分可以作为鉴定天麻的化学指纹成分.
For the first time, the volatile components of secondary protocorm are extracted by the improved vapor distillation. The compounds are determined by GC-MS, and their relative quantities are calculated by area normalization method. There are 42 volatile components from Gastrodia data B1. f. data（ 14 known ） , accounting for 63. 189% of total content; 48 constituents of the essential oils from Gastrodia elata Bl. f. viridis Mak （29 known） , accounting for 84. 313% of total content. The main components of Gastrodia elata B1. f. elata are 2,3,5,6-tetramethyl pyrazine （ 25. 331% ）, 2-pentyl-furan （ 11. 974% ） and E, E-2,4-decadienal （ 8.66% ）. The main components of Gastrodia elata Bl.f. viridis Mak are ethyl linoleate （ 15. 444% ） , styrene （ 10. 352% ） and ethyl palmitate （ 10. 066% ）. There arc 8 common components in the two kinds of Gastrodia elata B1 , which may be chemical dactylograms in determination of C, astrodia elata B1.
