云南省4种特色野生韧皮纤维植物化学组分分析
Analysis of Chemical Components of Four Characteristic Wild Bast Fiber Plants in Yunnan Province
摘要
Abstract
This study took four characteristic wild bast fiber plants in Yunnan province as the research objects and systematically analyzed the main chemical composition and key lignocellulosic properties of their stems.The results showed that the content ranges of cellulose,hemicellulose and lignin in the four plants were 25.57%to 43.75%,5.36%to 16.82%,and 12.15%to 31.71%,respectively.The degree of polymerization(DP)of the isolated cellulose ranged from 880 to 1 415,and the molecular weight of hemicellulose ranged from 43.62 to 200.73 kDa,with glucose or xylose serving as the primary sugar units.The syringyl/guaiacyl(S/G)ratio of acid-insoluble lignin ranged from 0.82 to 1.54.Among the four bast fiber plants,Ensete glaucum exhibited the lowest lignin content(12.19%)coupled with the highest holocellulose content(55.94%)and cellulose content(43.74%),making it the most suitable candidate for the papermaking industry.Broussonetia papyrifera ranked second in applicability.Si-da szechuensis Matsuda exhibited the highest lignin content(31.74%)and had a greater advantage in the lignocellulose-based biomass refining in-dustry,while Pouzolzia sanguinea exhibited the lowest holocellulose content(32.41%)and cellulose content(merely 5.38%)among the studied plants.Additionally,it showed relatively high ash content(12.96%)and extractives content(20.52%),indicating limited application potential in both the papermaking industry and the hemicellulose-based biomass conversion sector.关键词
