Abstract

The invention relates to a method for efficiently and accurately detecting melatonin content in Paeonia lactiflora Pall. The method comprises the following steps: preparing a reference solution, preparing a sample solution to be detected and carrying out high performance liquid chromatography-tandem mass spectrometry. The chromatographic peak of obtained melatonin detected in the Paeonia lactiflora Pall and the chromatographic peaks of other components can reach baseline separation, and are symmetrical in gauss peaks and good in peak patterns and can meet qualitative and quantitative requirements; the detection method of the melatonin content in the Paeonia lactiflora Pall provided by the invention is easy and simple to operate, high in sensitivity, strong in specificity, good in stability and accurate and reliable in results.

Description

technical field [0001] The invention relates to a method for efficiently and accurately detecting the content of melatonin in peonies. Background technique [0002] Peony (Paeonia lactiflora Pall.) is a perennial herbaceous plant of Paeoniaceae, which has high ornamental and medicinal value. The medicinal use of peony is mainly to extract its root system, and its aerial parts have no other use except for ornamental purposes, especially the petals. After the flowering period every year, the petals fall all over the ground, which has virtually caused a huge amount of resources. waste. Melatonin is an indole neuroendocrine hormone that has attracted much attention in recent years. It has many important physiological functions for the human body, such as improving sleep quality, enhancing immunity, slowing down aging, anti-tumor, Antioxidant and regulate circadian rhythm etc. Previous studies have shown that after eating fruits and vegetables rich in melatonin, the level of m...
