Determination of Nopinic Acid by Glass Column
Determination of Nopinic Acid by Glass Column Details:

Name: Packed column
Specification: 2m*3mm
Model: HH-Nopinic acid
Application: Determination of Nopinic Acid

Using β-pinene as the raw material, through KMnO4 oxidation assisted by ultrasonic irradiation, the synthesis conditions of nopinenic acid were optimized. Orthogonal experiments show that the sound intensity has the greatest influence on the yield of nopinic acid, followed by pH, raw material ratio, reaction temperature and time; single factor experiments show that the yield of nopinic acid increases with the increase of sound intensity Big. Under the optimized conditions of sound intensity of 0.38W/cm2, pH=10, n(β-pinene)/n(KMnO4)=1/2, and reaction at 15℃ for 30min, the yield of synthetic nopinic acid reached 66.4%.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used a hydrogen flame detector and a glass-packed column to determine the content of nopinic acid, with satisfactory results.
