Abstract
The invention relates to a detection method for measuring effective constituents of epimedium in cigarette tobacco shreds and main stream smoke of cigarettes. According to the detection method, a high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS) is utilized for detecting the content of the effective constituents, namely icariin and epimidin c, in the cigarette tobacco shreds and the main stream smoke of the cigarettes. The detection method sequentially comprises the following steps: (1) selecting and balancing the cigarettes; (2) preparing a reference substance solution; (3) preparing a cigarette tobacco shred sample solution; (4) preparing a sample solution in the main stream smoke of the cigarettes; and (5) carrying out HPLC-ESI-MS analysis on a to-be-analyzed sample. According to the detection method, the effective constituents of the epimedium in the cigarette tobacco shreds and the main stream smoke of the cigarettes can be effectively and completely extracted, and the content of the effective constituents of the epimedium in the cigarette tobacco shreds and the main stream smoke of the cigarettes can be accurately measured. The method is good in repeatability and high in analyzing and detection sensitivities.
Description
technical field [0001] The invention relates to a method for detecting the content of effective components of epimedium, in particular to a method for determining the content of effective components of epimedium in shredded cigarette tobacco and its mainstream smoke, and belongs to the technical field of tobacco detection. Background technique [0002] Epimedium is Epimedium brevicornum Maxim., Epimedium sagittatum (Sieb.et Zucc.) Maxim., Epimedium pubescens Maxim., or Epimedium koreanum The dry aerial part of Nakai has the effects of tonifying kidney yang, strengthening muscles and bones, and dispelling wind-dampness. For impotence and nocturnal emission, flaccidity of muscles and bones, rheumatic arthralgia, numbness and contracture. [0003] With the continuous advancement of the global tobacco control campaign, the public is increasingly concerned about smoking and health issues. It is believed that adding beneficial ingredients of natural plants to cigarettes can reduc...
