OBJECTIVE To optimize the processing technology of Epimedium koreanum roasted with suet oil and analyze its characteristic chromatogram before and after processing. METHODS The optimal processing technology was optimized by orthogonal experiments with frying power， frying time and medicinal temperature as factors using the comprehensive score of appearance traits （color+odor）， alcohol-soluble extract， the contents of icariin and baohuoside Ⅰ as evaluation index， then proceed with verification. The E. koreanum roasted with suet oil was prepared with the optimal technology. The characteristic chromatograms of 15 batches of E. koreanum were established with the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）， and then similarity analysis was also conducted. Clustering analysis， principal component analysis， and orthogonal partial least squares discriminant analysis were used to evaluate the differences in E. koreanum before and after processing. RESULTS The optimal processing technique for E. koreanum roasted with suet oil was as follows： first， heat 4 g of suet oil at a power of 600 W until it melts； next， when the temperature at the bottom of the pan reaches 140 ℃， add 20 g of E. koreanum silk and stir-fry for 6 minutes； finally， remove it and let it cool. Comprehensive score of 3 validation tests was 98.94 points　（RSD＜3%）. The established characteristic chromatogram of E. koreanum and E. koreanum roasted with suet oil were calibrated with 16 and 15 common peaks， respectively. Chromatographic peak 2 was determined to be chlorogenic acid， peak 5 to be chaohuoding A， peak 6 to be chaohuoding B， peak 7 to be chaohuoding C， peak 8 to be icariin， and peak 14 to be baohuoside Ⅰ. The similarities were all greater than 0.9. Results of cluster analysis and principal component analysis showed that E. koreanum and E. koreanum roasted with suet oil were clustered into distinct groups. The results of orthogonal partial least squares discriminant analysis showed that the variable importance projection values for peak 13， peak 15， peak 9， peak 1， peak 8， peak 12， peak 7， and peak 10 were all greater than 1. CONCLUSIONS The study successfully optimized the processing technology of suet oil-roasted E. koreanum. There are significant differences in the characteristic chromatograms of E. koreanum before and after processing. Among them， the chemical components corresponding to peak 13， peak 15， peak 9， peak 1， peak 8， peak 12， peak 7， and peak 10 may be the differential components of E. koreanum before and after processing.

OBJECTIVE To establish the fingerprints of dried Houttuynia cordata and its decoction pieces ，conduct chemometrics analysis and determine the contents of 5 flavonoids such as neochlorogenic acid. METHODS High performance liquid chromatography （HPLC）method was adopted. Using quercitrin as reference ，HPLC fingerprints of 10 batches of dried H. cordata and its decoction pieces were drawn. The similarity evaluation was conducted by Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition），the common peaks were also confirmed. SIMCA-P 14.1 software was applied for principal component analysis （PCA）and partial least square-discriminant analysis （PLS-DA），and the variable importance in projection（VIP）value more than 1 was considered as a standard to screen the differential components affecting the quality of these two products ；meanwhile，the contents of 5 components such as neochlorogenic acid in both products were determined by the same HPLC method. RESULTS There were 20 common peaks in 10 batches of dried H. cordata and 10 batches of its decoction pieces with the similarity values more than 0.960. A total of 5 common peaks were identified ，which were neochlorogenic acid （peak 1）， chlorogenic acid （peak 3），cryptochlorogenic acid （peak 4），rutin（peak 7）and quercitrin （peak 11）. The results of PCA and PLS-DA showed that dried H. cordata could be distinguished from its decoction pieces obviously ；the common peaks with VIP value greater than 1 were as follows ：peak 7（rutin），peak 20，peak 5，peak 13，peak 2，peak 18，peak 3（chlorogenic acid ）， peak 14，peak 17 and peak 19. The linear range of neochlorogenic acid ，chlorogenic acid ，cryptochlorogenic acid ，rutin and quercitrin were 3.77-60.29 μg/mL（r＝0.999 7），1.40-22.42 μg/mL（r＝0.999 5），3.76-60.22 μg/mL（r＝0.999 9），2.19-35.06 μg/mL （r＝0.999 9）and 25.49-407.88 μg/mL（r＝0.999 7），respectively. RSDs of precision ，stability（24 h）and reproducibility E-mail：20190394@njucm.edu.cn tests were all lower than 3％. The average recoveries of the above components in these two products were 98.72％-101.12％ and 98.86％ -100.63％ with RSDs less than 3％（n＝9）. In dried H. cordata ，the average contents of 5 components were 0.87，0.33，0.59，0.61 and 6.17 mg/g，while the average contents were 0.42，0.11，0.26，0.23 and 3.16 mg/g in its decoction pieces ，respectively. CONCLUSIONS HPLC fingerprint and the method of content determination are stable and feasible ，which could be used for the quality control of dried H. cordata and its decoction pieces. Besides ，rutin and other components may be the differential components which could affect the quality of these two products ；the average contents of the 5 flavonoids such as neochlorogenic acid in dried H. cordata all decrease after processing.

OBJECTIVE：To esta blish the m ethod for identifying Schizonepeta tenusfolia from different habitats based on odor information. METHODS ：The odor of S. tenusfolia from different habitats were identified by Heracles Ⅱ ultra-fast gas phase electronic nose. Qualitative analysis was conducted according to obtained chromatographic information combined with AroChemBase database and Kovats retention index qualitative database. Principle component analysis （PCA）and discriminant factor analysis （DFA）were conducted by using Alpha Soft V 14.2 software，and cluster analysis （CA）was performed with SPSS 22.2 software. RESULTS ：There were 16 common peaks in 15 batches of S. tenusfolia from different habitats. After comparison with AroChemBase database and Kovates retention index qualitative database ，a total of 13 possible components were obtained. The possible components and sensory description information of S. tenusfolia from different habitats were basically the same ，but only the content was different. The chromatographic peak intensities of common peak No. 2 were in descending order as Anhui ＞ Gansu＞Henan＞Hebei＞Jiangsu，the chromatographic peak intensities of common peak No. 6 were in descending order as Anhui ＞ Hebei＞Gansu≈Henan＞Jiangsu，the chromatographic peak intensities of common peak No. 9 were in descending order as Anhui ＞ Gansu＞Henan＞Jiangsu＞Hebei，the chromatographic peak intensity of common peak No. 13 were in descending order as Anhui ≈ Gansu＞Hebei＞Jiangsu＞Henan，which represented the chromatographic peak intensity of methyl formate （peak No. 2），α-pinene （peak No. 6），3-nonone（peak No. 9）and α-terpineol（peak No. 13）were significantly different due to the change of habitats. PCA results showed that the cumulative contribution rate of the first two principal components was 96.807％. Results of DFA showed that contribution rates of discriminant factor 1 and discriminant factor 2 were 92.089％ and 3.982％. CA results showed that when the distance was 10，15 batches of samples could be clustered into 3 categories，B1-B5 and J 1-J3 into one category ，A1-A3 into one category ，G1，G2，N1 and N 2 into one category. The results were basically consistent with those of PCA and DFA. CONCLUSIONS：Ultra-fast gas phase electronic nose technology can be used to identify S. tenusfolia from different habitats rapidly. Methyl formate ，α-pinene，3-nonone and α-terpineol may be the key factors to distinguish S. tenusfolia from different habitats.
