DHP的13C同位素示蹤及固體13CNMR分析

 

CARBON 13-ENRICHMENT OF DEHYDROGENATION POLYMERS OF MONOLIGNOLS TRACED BY SOLID-STATE 13 C NUCLEAR MAGNETIC RESONANCE

摘 要:以側(cè)鏈α位帶13 C同位素標(biāo)記的松柏醇葡萄糖苷作為起始物,在實(shí)驗(yàn)室中模擬木質(zhì)素生物合成過(guò)程人工合成脫氫聚合物(DHP),得到帶13 C標(biāo)記的DHP.用高分辨率固體13 C NMR和紅外光譜對(duì)DHP進(jìn)行了分析.紅外分析結(jié)果顯示:該實(shí)驗(yàn)條件下用松柏醇葡萄糖苷合成的DHP同天然銀杏木材的磨木木質(zhì)素(MWL)在組成和結(jié)構(gòu)上有較好的相似性.13 C NMR證明了β-O-4、β-β、β-5和松柏醇結(jié)構(gòu)為DHP的主要結(jié)構(gòu),另有少量香蘭素結(jié)構(gòu)和α-位亞甲基結(jié)構(gòu).
關(guān)鍵詞:脫氫聚合物;木質(zhì)素; 碳-13同位素示蹤;固體13 C NMR
