Abstract:
OBJECTIVE：To i nvestigate the spectrum-effect relationship of analgesic and anti-inflammatory effects of ethyl acetate extract from Zhuang medicine Stahlianthus involucratus from different habitats. METHODS ：Ten batches of S. involucratus from different habitats were used as samples to investigate the anti-inflammatory and analgesic activities of ethyl acetate extracts by xylene induced ear swelling test and acetic acid induced writhing test in mice. HPLC fingerprints of 10 batches of ethyl acetate extract from S. involucratus were established and their similarity was evaluated by using Similarity Evaluation System of TCM Chromatogram Fingerprint （2012 edition），and the common peaks were identified by comparison with the control. The spectrum-effect relationship of anti-inflammatory and analgesic effects of ethyl acetate extract from S. involucratus were analyzed on the basis of Pearson correlation coefficient （auricle swelling degree and writhing times in 15 min as pharmacodynamic indexes ）and Grey relational analysis （inhibition rate of ear swelling and analgesic rate as pharmacodynamic indexes ）. RESULTS ： batches of ethyl acetate extract from S. involucratus had obvious anti-inflammatory and analgesic effects ； inhibition rates of ear swelling in mice were 46.43％-55.16％，and the analgesic rates of mice were 45.56％-52.72％. A total of 18 common peaks were identified in 10 batches of samples ，andthe similarity between them and the control fingerprint was 0.994-0.997. Compared with substance control ，the pea ks 1，2 and 4 were identified as protocatechuic acid ， p-hydroxy- 0771-4953513。E-mail：liangjie1101@126.com benzoic acid and p-hydroxybenzaldehyde，respectively. Results of Pearson correlation analysis showed that peak 10 and peak 18 were significantly negative correlated with auricle swelling degree and writhing times in 15 min（r were values －0.853，－0.738，P values were 0.002，0.015，respectively）. Results of Gray correlation degree analysis showed that the correlation degree of 18 common peaks with inhibition rate of ear swelling and analgesic rate were all greater than 0.65；among them ，peaks 14，1（protocatechuic acid ），17，9，4（p-hydroxybenzaldehyde），2（p-hydroxybenzoic acid ）， 16，7 and 6 showed the relatively high correlation degree （correlation degree ＞0.7）；peak 1（protocatechuic acid ），17，14，9，16，2 （p-hydroxybenzoic acid ）and 4（p-hydroxybenzaldehyde）showed the relatively high correlation degree （correlation degree ＞0.7）. CONCLUSIONS：The ethyl acetate extract of S. involucratus show good anti-inflammatory and analgesic effects. Peak 1 （protocatechuic acid ），2（p-hydroxybenzoic acid ），10，14，17，18 may be its main active ingredients.
