To obtain optimum quality Lycium barbarum extract wine with different degrees of alc., UV and visible spectrophotometry, high-performance liquid chromatog., and gas chromatog.-mass spectrometry were used to analyze the three different alc. Lycium barbarum extract wine samples (42%vol, 45%vol, 53%vol). The color, flavonoids, polysaccharides, betaine, and aroma components were investigated during the extraction period. Results showed that the optimal extraction time of 42%vol Lycium barbarum extract wine was 10 d, the Lycium barbarum extract wine flarohoids content was 0.046 mg/mL, the Lycium barbarum polysaccharide content was 9.36 mg/mL, the betaine content was 1.412 mg/L, and the typical aroma component Et caprylate content was 1.608 mg/mL. The optimal extraction time of 45%vol Lycium barbarum extract wine was 10 d, the Lycium barbarum extract wine flarohoids content was 0.045 mg/mL, the Lycium barbarum polysaccharide content was 7.89 mg/mL, the betaine content was 3.070 mg/L, and the typical aroma component Et caprylate content was 1.779 mg/mL. The optimal extraction time of 53%vol Lycium barbarum extract wine was 20 d, the Lycium barbarum extract wine flarohoids content was 0.031 mg/mL, the Lycium barbarum polysaccharide content was 5.83 mg/mL, and betaine content was 1.089 mg/L, and the typical aroma component Et caprylate content was 2.785 mg/mL. All the prepared Lycium barbarum extract wines had an acceptable color. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Application In Synthesis of Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Isopentyl hexanoate
