3 octanol

Sodium chloride was of analytical grade and purchased from GuangXi XiLong Chemical Co. Ltd. (Guangxi, China). Internal standards included (S)-(+)-2-octanol, 3-octanol, adonitol, cyclohexanone, 2-octanone, 3-octanone, 2-nonane, 3-nonane, octyl acetate, ethyl caprylate, and triacetine, purchased from Shanghai Yuanye Bio-Technology Co. Ltd. (Shanghai, China) and Aladdin (Shanghai, China), and all are of chromatographic grade.

Controls, consisting of sugars (fructose, sorbitol, glucose, sucrose), organic acids (quinic acid, malic acid, citric acid, succinic acid), phenolic compounds (coumaric acid, procyanidin B1, neochlorogenic acid, catechin, vanillic acid, chlorogenic acid, epicatechin, rutin, and quercetin), and 3-octanol were bought from Shanghaiyuanye Bio-Technology Co., Ltd. (Shanghai, China). The reagents for 2,2’-azinobis (3-ethylbenzothiazoline-6-sulphonate) (ABTS⁺), 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC) were bought from TANEE CHEMICAL LTD. Analytical-grade reagents were bought from business sources for the remaining materials.

The standard products with the concentration of 99%, including sugars (sucrose, sorbitol, fructose, glucose), organic acids (quinic acid, malic acid, citric acid, succinic acid), phenolic compounds (p-coumaric, procyanidins b, neochlorogenic acid, catechinic, vanillic acid, chlorogenic acid, epicatechin, rutin, quercetin, kaempferol) and 3-octanol were obtained from Yuanye Biotechnology Co., LTD (Shanghai, China). The 2,2′-azinobis (3-ethylbenzothiazoline-6-sulphonate) (ABTS⁺), ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and cupric reducing antioxidant capacity (CUPRAC) reagents were purchased from Beifang Tianyi Chemical Reagents Factory (Tianjin, China). All other chemicals were of analytical grade.
