The chemical composition of lignin and lipids of bast fibers from industrial hemp (Cannabis sativa) used for high-quality paper pulp production was studied. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of fibers showed a lignin with a p-hydroxyphenyl:guaiacyl:syringyl unit (H:G:S) molar proportion of 13:53:34 (S/G ratio of 0.64). p-Hydroxycinnamic acids, namely, p-coumaric and ferulic acids, were found in only trace amounts. Among the lipids, the main compounds identified by GC/MS of the hemp fibers extracts were series of n-alkanes, free and esterified sterols and triterpenols, waxes, and long-chain n-fatty acids. Other compounds such as n-aldehydes, n-fatty alcohols, steroid hydrocarbons, and steroid and triterpenoid ketones as well as steryl glycosides were also found.
对用于高质量纸浆生产的工业大麻（大麻属）韧皮纤维的木质素和脂质的化学成分进行了研究。纤维的热解气相色谱/质谱联用（Py-GC/MS）分析表明，木质素中对羟基苯基：愈创木基：紫丁香基单元（H:G:S）的摩尔比例为13:53:34（S/G比为0.64）。对羟基肉桂酸，即对香豆酸和阿魏酸，仅以痕量存在。在脂质中，通过气相色谱/质谱联用（GC/MS）对大麻纤维提取物鉴定出的主要化合物是一系列正构烷烃、游离和酯化的甾醇和三萜醇、蜡以及长链正脂肪酸。还发现了其他化合物，如正醛、正脂肪醇、甾体烃、甾体和三萜酮以及甾醇糖苷。
