The main component of ramie glial was pectin, hemicellulose and lignin; The single factor on degumming of ramie test was respectively analyzed with a high vigorous of pectinase KDN and TZ-888 compound enzyme （mainly xylanase and mannanase on the pH value, bath ratio, dosage of enzyme, metal ions, temperature and time.The orthogonal test of L9（34 were done by bath ratio, dosage of enzyme, temperature and time. The results showed that the best compages of KDN pectinase on degumming was 1∶12 of bath ratio,pH 8.6,1 mmol/L Mg2+,300 IU/g of KDN pectinase,35℃、6 h;the best compages of TZ-888 compound enzyme on degumming was 1∶18 of bath ratio,pH 4.0,1 mmol/L Ca2+, 500 IU/g of TZ-888 compound enzyme,45 ℃,6 h.

摘 要：本研究根据苎麻胶质的主要成分为果胶、半纤维素和木质素，用高活性的KDN果胶酶和TZ-888复合酶（主要是木聚糖酶和甘露聚糖酶）从pH值、浴比、酶用量、金属离子、温度、脱胶时间等方面进行单因素试验，然后选取影响显著的浴比、酶用量、温度，时间进行四因素三水平的脱胶试验，结果表明鲜麻采用KDN果胶酶脱胶最佳组合为浴比1：18，pH 8.6， 1 mmoL/L Mg2+，酶用量300 IU/g，温度35 ℃、时间6 h时处理，TZ-888复合酶脱胶最佳组为浴比1：12，pH 4.0， 1 mmoL/L Ca2+，酶用量500 IU/g，温度45 ℃，时间6 h进行脱胶为优化的试验条件。

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.
