The most important quality of Chinese herbal medicine is reflected in the issue of pesticide residues, which not only affects people's health, but also is the biggest issue that hinders the development of import and export trade. It is particularly important to develop rapid, efficient, and highly sensitive methods for the detection of pesticide residues in Chinese herbal medicines and to evaluate the quality of Chinese herbal medicines. Honeysuckle is the flower bud of honeysuckle, a perennial vine, honeysuckle. Alias ​​honeysuckle flowers, silver flowers, two flowers, double flowers, heron flowers, Su flowers, double flowers, golden vine flowers. Flowers (honeysuckle), stem vines (cane-vine), roots, and leaves can be used as medicine. High-throughput tissue grinders are used for sample grinding when they are being studied.

This article mainly uses the GC-MS technology to analyze 50 common pesticide residues in honeysuckle. The high-throughput tissue grinder is involved in sampling, and proposes reasonable use suggestions for its use. At the same time, it provides a reference for product monitoring and development of honeysuckle. Use to provide scientific basis. From the results of sample determination, among the 50 pesticides tested, the detection rate of cypermethrin was the highest, accounting for 51.2% of the detection rate, followed by triadimenol and dicofol, which accounted for 26.8% and 14.6%, respectively. It can be seen that the input of cypermethrin in the growth process of honeysuckle is relatively large. However, although some drugs are not used frequently, they also have serious problems in the use of specifications. In addition, through data analysis, it can be found that the pesticide residue content of honeysuckle varies significantly in different growth processes, and the residue content of the general fresh wet flower is significantly higher than that of dried flowers.
Honeysuckle is easily threatened by pests and diseases during planting. In this study, high-throughput tissue grinders and other instruments, GC-MS were used to analyze the 50 common pesticide residues in 87 samples, and the use of pesticide input in honeysuckle was initially understood. Frequency and dosage data, the results show that the lack of relevant norms and technical guidance for pesticide use, it is recommended to use the relevant registration data of pesticides in China, according to the prescribed number of uses and the use of dose medication, if necessary, alternating with the same utility drugs, at the same time, within a certain safety interval Stop the use of drugs to ensure the safety of drugs. In addition, honeysuckle should be avoided as much as possible, and it is best to use products that have undergone storage, processing, and formulation processing.
