Embodiment 1

[0019] Embodiment 1, the identification method of different origins of fennel

[0020] Select 10 batches of fennel decoction pieces from different origins (Shanxi Yingxian, Shanxi Shuozhou, Gansu Jiuquan, Gansu Minqin, Guangxi Yulin, Inner Mongolia Tuoxian, Inner Mongolia Linhe, Guangdong Province, Sichuan Province, Liaoning Dalian) to extract volatile oil , respectively determined the content of artemisinin, anethole, (R)-(+)-limonene, anti-aging agent 2246, L(-)-fenzone and terpinene in each volatile oil, and investigated the composition differences of fennel volatile oil from different producing areas . see results figure 1 .

[0021] The volatile extraction method is steam distillation extraction: take 300g of fennel from different origins, place them in a steam distillation device, add 10 times the amount of water, soak for 30 minutes, boil for 8 hours, and collect volatile oils respectively.

[0022] The determination method of volatile oil is GC-MS analysis:

Abstract

The invention provides an identification method of a fennel producing area. The method comprises the following steps: (1) taking a to-be-detected fennel sample, extracting volatile oil, and respectively determining the content of each of estragole, fennel anethole, (R)-(+)-limonene, an antioxidant 2246, L(-)-fenchone and terpinene in the volatile oil; and (2) bring the content of each of the estragole, the fennel anethole, the (R)-(+)-limonene, the antioxidant 2246, the L(-)-fenchone and the terpinene into formulas of PC1 = 0.03 x (R)-(+)-limonene - 0.90 x estragole - 0.21 x fennel anethole -0.09 x antioxidant 2246 - 0.27 x L(-)-fenchone - 0.25 x terpinene, and PC2 = 0.07 x estragole - 0.66 x (R)-(+)-limonene - 0.50 x fennel anethole - 0.52 x antioxidant 2246 + 0.16 x L(-)-fenchone + 0 .12 x tertenene, and then carrying out determination according to numerical values of PC1 and PC2. Through the identification method of the invention, quality difference of 10 types of fennel of different producing areas is successfully identified.

Description

technical field [0001] The invention belongs to the technical field of medicinal material detection, and in particular relates to a method for identifying the origin of cumin. Background technique [0002] Fennel was first recorded in "Tang Materia Medica", also known as soil fennel and Guxiang. It is the dry and mature fruit of Umbelliferae fennel Foeniculum vulgare Mill.
