OBJECTIVE To optimize ethanol extraction process of Yihuang powder. METHODS An orthogonal experiment was designed by reflux extraction with ethanol volume fraction， liquid-to-material ratio， and extraction time as investigation factors. The parameters used were the contents of hesperidin， nobiletin， tangeretin， gallic acid， chebulagic acid， chebulinic acid， liquiritin， glycyrrhizin， eugenol， and the paste-forming rate. The analytic hierarchy process （AHP） was used to calculate the comprehensive score. The optimal ethanol extraction process parameters of Yihuang powder were determined by verifying the results predicted by orthogonal experiment and genetic algorithm （GA）-back propagation neural network （BP neural network）. RESULTS The optimal ethanol extraction process parameters， as optimized by orthogonal experiment， were as follows: ethanol volume fraction of 60%， liquid-solid ratio of 14∶1 （mL/g)， extraction time of 90 min， and extraction for 2 times. The comprehensive score obtained by verification was 79.19. Meanwhile， the optimal ethanol extraction process parameters， optimized by GA-BP neural network， were ethanol volume fraction of 65%， liquid-solid ratio of 14∶1 （mL/g )， extraction time of 60 min， and extraction for 2 times. The comprehensive score obtained by verification was 85.30， higher than the results obtained from orthogonal experiment. CONCLUSIONS The optimization method of orthogonal experiment combined with GA-BP neural network is superior to the traditional orthogonal experiment optimization method. The optimized ethanol extraction process of Yihuang powder is stable and reliable.

OBJECTIVE To optimize the honey processing technology of Phellinus igniarius. METHODS The key factors of honey processing technology of P. igniarius （honey-water ratio， the mass ratio of honey-water to P. igniarius， the frying temperature and the frying time） were investigated by orthogonal test combined with analytic hierarchy process to determine the optimal technological parameters， using the internal quality （the contents of ergosterol， protocatechuic aldehyde and protocatechuic acid） and appearance traits as evaluation indexes.

OBJECTIVE To compare the similarities and differences between raw and different preparations of Terminalia chebula based on fingerprint， antioxidant spectrum-effect correlation and multi-component contents， and to provide a reference for searching for modern processing methods of T. chebula that are similar to classical ancient methods. METHODS Ten batches of raw and different preparations of T. chebula （single stir-fried products， bran-roasted products， sand-scorched products， ash-roasted products， stir-fried charcoal products， and wine-steamed products） were used as test samples. The high-performance liquid chromatography （HPLC） fingerprints of different samples were established by using the Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）， the chromatographic peaks were identified， and chemometrics analysis was carried out. At the same time， HPLC method was used to determine the contents of 8 identified components. The antioxidant capacity of raw and different preparations of T. chebula was determined by DPPH free radical scavenging method， and the spectrum- effect relationship was analyzed. RESULTS A total of 20 common peaks were identified in the fingerprints of the raw and different preparations of T. chebula， and the similarity of each sample was ＞0.9. Nine common peaks were identified from the raw and different preparations of T. chebula， including chromatographic peak 2 （chebulic acid）， 3 （gallic acid）， 6 （punicalagin A）， 8 （punicalagin B）， 12 （corilagin）， 15 （chebulagic acid）， 18 （ellagic acid）， 19 （1，2，3，4，6-O-pentagalloyl glucose）， 20 （chebulinic acid）， etc. Compared with crude drug， the contents of the above 8 components （punicalagin A and B are recorded as punicalagin） in different preparations of T. chebula were changed， and the changes of the contents of the stir-fried charcoal and wine-steamed products were more obvious than those of other processed products. Chemometric analysis showed that the fingerprints of stir-fried charcoal and wine-steamed products of T. chebula were obviously distinguished from other processed products， and the fingerprint information of raw products and other processed products of T. chebula was partially overlapped. Four main differential components （chebulinic acid， chebulagic acid， gallic acid， ellagic acid） were obtained between raw and processed products of T. chebula； and four main effective components （chebulinic acid， chebulagic acid， gallic acid， corilagin） were obtained by analyzing the spectrum-effect relationship of antioxidant activity. The single stir-fried product of T. chebula showed the strongest antioxidant activity. CONCLUSIONS The single stir-frying method is a modern processing method of T. chebula which is similar to the classical ancient method and is more excellent.

OBJECTIVE To optimize the extraction and separation process of chebulagic acid and chebulinic acid from Terminalia chebula. METHODS Based on single factor experiment， with particle size， liquid-solid ratio， extraction time and extraction times as factors， using the contents of chebulagic acid and chebulinic acid as indexes， orthogonal experiment was designed to optimize the extraction process of chebulagic acid and chebulinic acid. Taking sample concentration， elution solvent and the ratio of eighteen-group bonded silicone reverse phase （ODS） to the amount of raw medicine as factors， the separation processes of chebulagic acid and chebulinic acid were optimized.

After 3 experiments， the average comprehensive score was 99.33 （RSD＝ 0.68%， n＝3）， and the average contents of chebulagic acid and chebulinic acid were 107.05 and 58.32 mg/g， respectively. The optimal separation process of the two components included the concentration of sample loading solution was 0.5 g/mL （1 mL was equivalent to 0.5 g of medicinal materials）， the ratio of ODS to the amount of raw medicine was 10∶1.5 （g/g）， methanol-water （1∶4， V/V） eluted chebulagic acid， methanol-water （3∶7， V/V） eluted chebulinic acid. After 3 experiments， the average total yields of the two components were 53.33%， 39.23%. After recrystallization， the purity of both components was 100%. CONCLUSIONS Established extraction and separation process of chebulagic acid and chebulinic acid is simple and feasible.

OBJECTIVE To study the content changes of ch emical constituents of processed products of Terminalia chebula at different temperatures ，and to compare its anti-ulcerative colitis effect. METHODS Processed products of T. chebula at different temperatures（160，180，200，220，240，260，280，300 ℃）were prepared by sand scalding technology. HPLC method was adopted to determine the contents of gallic acid ，chebulagic acid ，chebulinic acid and ellagic acid in crude drug and processed products of T. chebula at different temperatures. The mice were divided into blank group ，model group ，Mesalazin enteric-coated tablets group （positive control ，0.4 g/kg），crude drug and processed products groups of T. chebula at different temperatures （1.3 g/kg），with 10 mice in each group. Except for blank group ，other groups were given 6％ acetic acid 0.1 mL via anus to induce ulcerative colitis model. After modeling ，blank group and model group were given water intragastrically ，and other groups were given relevant drug intragastrically ，20 mL/kg，once a day ，for consecutive 7 days. The general physical signs of mice in each group were observed and the body weight was recorded. The colorectal length and index ，serum levels of related inflammation indexes [superoxide dismutase （SOD），malondialdehyde （MDA），interleukin-10 （IL-10），IL-1 β ，tumor necrosis factor α （TNF-α）] were detected. The pathomorphological changes of colon and rectum were observed ，and the comprehensive score of pharmacodynamics was performed. RESULTS With the increase of processing temperature ，the contents of chebulagic acid and chebulinic acid decreased gradually ，the content of gallic acid increased first and then decreased ，and the content of ellagic acid increased. Compared with model group ，the general physical signs ，body weight ，colorectal length ，colorectal index and related inflammation indexes were all improved significantly in crude drug and processed products groups of T. chebula at different temperatures（P＜0.05 or P＜0.01）. The glandular recess structure of colorectal tissue was repaired ，the infiltration of inflammatory cells was reduced ，and the comprehensive score of efficacy of processed products prepared at 260 ℃ was the highest. CONCLUSIONS The contents of chemical components in T. chebula processed at different temperatures change significantly and their anti-ulcerative colitis effects are different. The processed products of T. chebula prepared at 260 ℃ show the best anti-ulcerative colitis effect.
