“辨狀論質(zhì)”看中藥材苦杏仁走油

　　[摘要]通過苦杏仁走油前后的質(zhì)量比較，探討苦杏仁走油變質(zhì)現(xiàn)象的感官判別及其物質(zhì)內(nèi)涵。該研究對苦杏仁樣品走油前后的脂肪油含量、酸值、過氧化值進行了測定，并采用HPLC，GCMS分別檢測了苦杏仁苷、苦杏仁脂肪酸等。利用電子感官儀器（色度儀、電子鼻）量化并對比苦杏仁樣品走油前后的顏色、氣味；同時與上述結(jié)果作相關(guān)性分析。結(jié)果顯示苦杏仁走油后顏色由黃白變棕黃，出現(xiàn)酸味；苦杏仁苷含量下降，酸值、過氧化值顯著增高，脂肪酸成分發(fā)生變化；藥材的外表特征與內(nèi)在質(zhì)量的變化具有顯著相關(guān)性。 “感官分析質(zhì)量鑒別系統(tǒng)” 能為預測中藥化學成分的含量、初步判斷中藥優(yōu)劣及質(zhì)量實時監(jiān)測提供一定科學依據(jù)；為中藥貯藏的“事先預測、事中干預、事后鑒別”提供新的思路與參考。

　　[Abstract]This article aims to compare the qualities of Armeniacae Semen Amarum before and after rancidness， in order to study the rancidness of Armeniacae Semen Amarum In the experiment， content of fatty oil， acid value and peroxide value were determined before and after rancidness，respectively Meanwhile， HPLC， GCMS were utilized to analyze laetrile and fatty acid components Besides， colorimeter and enose were introduced to quantify and compare "color and odor" A correlation analysis was conducted on the above results The results showed that color of postrancidness Armeniacae Semen Amarum changed from yellow to brown， with sour and lower content of laetrile On the contrary， acid and peroxide values increased significantly， with changes in fatty acid component There was a considerable correlation between appearance characteristics and changes in internal quality The "sensory analysisquality identification system" can provide a certain scientific basis for prediction of the content of chemical components in traditional Chinese medicine， preliminary judgment of quality of traditional Chinese medicine and realtime quality monitoring， which offers us novel ideas and reference for storage principles of traditional Chinese medicines of "preevent prediction， duringevent intervention and postevent identification"
