Chemical constituents of volatile oil from Hubei lancea by three processing methods was written by Zhang, Hu;Xia, Xin-zhong;Xiang, Li-juan;Mao, Kun. And the article was included in Zhongguo Shiyan Fangjixue Zazhi in 2015.Product Details of 605-94-7 This article mentions the following:
Objective: Anal. and comparison of Hubei Mao herb fried gluten, rice water broiled, fried and other three kinds of different processing methods in the chem. composition of volatile oil. Methods: Application of steam distillation to extract three different processing methods of Hubei lancea volatile constituents by GC-MS anal. and identification of the chem. composition, and the use of peak area normalization method to calculate the relative quality of each component scores. Results: From three kinds, 88 kinds of volatile oil components were separated, 87 kinds of volatile chem. composition were identified, their common ingredients were 51 kinds, and the identified chem. composition of each sample on average accounted for 94.61% of total volatile oil. Conclusion: There are some differences between three kinds of Hubei lancea volatile chem. composition and contents of the different processing methods. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Product Details of 605-94-7).
2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Product Details of 605-94-7
