Beeswax, also known as yellow wax or beeswax, is a medicinal substance listed in the Chinese Pharmacopoeia Beeswax is refined from the wax secreted by the Chinese honeybee Apis cerana Fadricius or the Italian honeybee Apis mellifera Linnaeus in the family Apidae The Shennong Bencao Jing records that beeswax has the function of "nourishing qi, preventing hunger, and enduring aging" Beeswax extract is a white or off white wax powder obtained by saponification, separation, and extraction of beeswax. It is a mixture of natural higher alcohols, and the main components of beeswax extract for reducing blood lipids are triacontanol and octacosanol
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for detecting the content of octacosanol in sugar by gas chromatography. Method: Sugar samples were dissolved by distillation, extracted with ethyl acetate, and concentrated by vacuum distillation. The concentrated extract was separated using a 3% -5% OV-17-Cromosorb WAW DMCS packed column, detected by gas chromatography, and quantified by external standard method. The standard for 28 octane alcohols
Name: Filler Column
Fixed phase: Chromosorb WAW DMCS with acid washed silicides contains a support (A.le) coated with approximately 3% -5% OV17 fixative,
model: OV-17
Specification: Length of 3 meters, inner diameter of 3 meters
Zui high temperature: 320 ° C
Application: GB/T 32947-2016 Determination of Octacosanol and Triadecanol in Beeswax by Gas Chromatography
This standard specifies the method for determining the content of octacosanol and triacontanol in beeswax.
This standard is applicable to the determination of octacosanol and triacontanol content in beeswax.
