四川雪茄烟生物碱质量分数及烟碱转化率分析
Analysis of alkaloid mass fraction and nicotine conversion rate of Sichuan cigar tobacco
摘要
Abstract
[Objective]This study was conducted to clarify the alkaloid mass fraction,nicotine conver-sion rate and nicotine conversion problems of different varieties of cigar tobacco in Sichuan,and to screen cigar tobacco strains according to different nicotine conversion rates in order to optimise the quality and improve the safety of cigar tobacco leaves.[Method]The central leaves of 22 varieties of cigar tobacco from Sichuan were analysed to determine the alkaloid and total nitrogen mass fraction of each test variety and to calculate the nicotine conversion rate.[Result]1)The alkaloid mass fraction of the 22 varieties of cigar tobacco varied significantly and had serious nicotine conversion problems,with total alkaloid mass fraction ranging from 1.07 to 4.40 per cent,with a mean of 2.59 per cent,nicotine mass fraction ranging from 0.23 to 3.40 per cent,with a mean of 1.87 per cent,and nicotine reduction ranging from 0.04 to 2.33 per cent,with a mean of 0.44 per cent,for all the varieties tested.The nicotine conversion rate ranged from 2.57%to 89.17%,with an average value of 17.52%,and the coefficients of variation for nicotine reduction and nicotine conversion rate of cigaril-los of various varieties reached 130.96%and 132.22%,respectively.2)There were significant differ-ences in the proportion and distribution of the 22 varieties of cigar tobacco converted strains in Sich-uan,among which Dexue 202 had less problem of nicotine conversion,with an average nicotine con-version rate of 2.57 per cent,and Dexue 202,Wanmao No.3 and SCX14 had a high proportion of non-converted strains,with 95 per cent,90 per cent and 80 per cent,respectively.The groups of SCX4 and Chuanxue No.4 had a serious problem of nicotine conversion,with an average of nicotine and descalcitrate mass fraction of 0.23%and 2.33%,0.45%and 1.50%,respectively,with average nicotine conversion rates as high as 89.17%and 73.73%,and the proportion of converted strains as high as 100%and 85%,respectively.[Conclusion]It is necessary to strictly select non-transformed plants for variety improvement by inducing transformation traits and identifying transformed plants in the pre-growth period of cigar tobacco varieties,and retaining non-transformed plants for planting.关键词
