OBJECTIVE:To study the common characteristic component peaks in water decoction of crude curcumae radix and the vinegar roasted products from 4 different sources,compare the contents of its water decoction,and provide reference for resolv-ing the multi-source of curcumae radix piece in clinical application,complementing and improving the quality standard of curcumae radix. METHODS:HPLC was used to determine the characteristic spectrums of crude curcumae radix and the vinegar roasted prod-ucts from different sources (Curcuma wenyujin,Curcuma kwangsiensis,Curcuma longa,Curcuma phaeocaulis),and component analysis was conducted by using fingerprint software and mirror comparison. And the changes of water decoction content before and after vinegar roasted were compared. RESULTS:Both crude curcumae radix and the vinegar roasted products from 4 different sourc-es had 7 common characteristic component peaks. Vinegar roasted had effect on peaks in different degree,some peaks areas were in-creased,some peaks areas were reduced,some peaks were generated,and some peaks were disappeared. However,the common components of curcumae radix from different sources showed no qualitative changes after vinegar roasted,except the increase or de-crease in peak areas. Areas of 5 common component peaks were increased in the 7 common components of C. wenyujin,C. kwang-siensis and C. longa after vinegar roasted,and only 3 in C. phaeocaulis after vinegar roasted. Contents of 4 water decoctions were increased after vinegar roasted. CONCLUSIONS:There are 7 common components in curcumae radix from 4 different sources. Vin-egar roasted has no qualitative effect on common components,while it can increase the chromatographic peak areas and contents of water decoction.

METHODS ： Using aspirin as positive control ，acetic acid writhing method was used to investigate the effects of 4 sources of Curcumae Radix decoction pieces water extract on writhing latency and times of writhing in mice. The moisture contents of 4 sources of Curcumae Radix decoction pieces （10 batches of each source ，the same below ）were determined according to the drying method in 2015 edition of Chinese Pharmacopoeia （part Ⅳ）. The yield of water extract in 4 sources of Curcumae Radix decoction pieces were investigated by hot dipping method ，the contents of curcumenol in water extract of 4 sources of Curcumae Radix decoction pieces were determined by HPLC ，and comparison was conducted. RESULTS ：Compared with model group ，aspirin and water extracts of 4 sources of Curcumae Radix decoction pieces could significantly prolong the writhing latency of model mice ，and the water extracts of C. wenyujin and C. phaeocaulis could significantly reduce the writhing times of model mice （P＜0.05 or P＜0.01）. For C. wenyujin ，C. kwangsiensis ，C. phaeocaulis and C. longa ，the contents of moisture were 7.39％-8.80％，7.88％-9.88％，7.66％- 10.5468/ogs.2019.62.6.382 9.86％ and 7.68％-10.20％；the average yield of water extract were 46.30％，60.40％，38.65％，42.99％；the average contents of curcumenol in water extract were 0.271，0.066，0.310，0.058 mg/g. Except for a few batches ，the higher the yield of water extract，the higher the content of curcuminol in the same source of Curcumae Radix decoction pieces. CONCLUSIONS ：Four sources of Curcumae Radix decoction pieces have analgesic effect. The contents of curcumenol in C. wenyujin and C. phaeocaulis were similar ，and the contents of curcumenol in C. kwangsiensis and C. longa about 1/5 of that in C. phaeocaulis and C. wenyujin .

OBJECTIVE： To study the effects of different processing technologies on the quality of Salvia miltiorrhiza decoction pieces， and to provide reference for original processing of S. miltiorrhiza to decoction pieces. METHODS： Fresh S. miltiorrhiza from two areas of Shandong province （Pingyin and Pingyi） were processed into decoction pieces by 24 kinds of processing technology， such as fresh cutting， dry cutting after dried 30％， dry cutting after dried 50％， full dry cutting， traditional cutting [from 2015 edition of Chinese Pharmacopoeia （part Ⅰ）， shorted as pharmacopecia]， cutting after full dry steamed， cutting after fresh steamed， cutting after dry 30％ steamed， cutting after fresh boiled （then divided into air-drying and baking）. The qualities of decoction pieces were evaluated for original processing comprehensively through appearance character and the contents of moisture， water soluble extract， ethanol soluble extract， and effective components （tanshinones and salvianolic acid B）. RESULTS： From the appearance characteristics， the traditional cutting， cutting after fresh steamed and cutting after dry 30％ steamed， decoction pieces had better surface color and high yield， which were more in line with the relevant description of the pharmacopecia. From the contents of moisture and effective components， the contents of moisture of S. miltiorrhiza decoction pieces were 3.60％-10.40％； the contents of water soluble extract were 51.07％-70.18％； the contents of ethanol soluble extract were 15.08％-20.36％， all above were all in line with the standard of pharmacopecia. The contents of tanshinones were 0.16％-0.79％. Only fresh-cut and fresh-boiled-cut baked samples from Pingyin were not up to the standard of pharmacopecia （tanshinones content was not less than 0.25％）， while those from Pingyi were up to the standard. The contents of salvianolic acid B were 4.51％-8.68％， which were all in line with the standard of pharmacopecia （salvianolic acid B content was not less than 3.0％）. In all processing technologies， the indexes of decoctions made by steaming， cutting and air-drying were higher. CONCLUSIONS： Comprehensive considering from the aspects of appearance character and effective components content， suitable processing method of S. miltiorrhiza raw medicinal materials is cutting after steamed and air-drying.

ObjectiveTo investigate the quality of Ligustri Lucidi Fructus in the market， and the moisture， extract， determination of Zhuyao and Douchi Ligustri Lucidi Fructus were compared to increase the utilization rate of Ligustri Lucidi Fructus. MethodThe properties， moisture， total ash， alcohol-soluble extract content and thin layer chromatography （TLC） identification were determined by the methods of Ligustri Lucidi Fructus included in the 2020 edition of Chinese Pharmacopoeia， and high performance liquid chromatography （HPLC） fingerprint and determination of specnuezhenide and salidroside were established with the mobile phase of 0.2% phosphoric acid aqueous solution （A）-acetonitrile （B） （0-70 min， 92%-65%A） for gradient elution， and the detection wavelength of 220 nm at 0-14 min and 225 nm at 14-70 min. The two different characters of Ligustri Lucidi Fructus were comprehensively compared by the above indicators. ResultExcept for one batch which did not meet the requirements due to the quality of harvesting， the other 12 batches of samples all met the requirements of the 2020 edition of Chinese Pharmacopoeia， but there were two different characters. Comparing the two different characters of Ligustri Lucidi Fructus， it is found that the moisture， total ash， extract， salidroside and specnuezhenide contents of Zhuyao samples were 2.22%-5.19%， 3.91%-4.49%， 32.56%-40.95%， 0.073%-0.170% and 1.45%-4.14%， and these values of Douchi samples were 3.57%-5.61%， 3.65%-4.44%， 41.31%-46.70%， 0.041%-0.067% and 3.01%-4.20%， respectively. ConclusionThe contents of extract and specnuezhenide of Douchi Ligustri Lucidi Fructus are mostly higher than those of Zhuyao Ligustri Lucidi Fructus， while the content of salidroside is lower than that of Zhuyao samples， and there are no significant differences in moisture， TLC identification and total ash content. Based on the above research， if the main purpose is to extract salidroside， it is recommended to choose Zhuyao Ligustri Lucidi Fructus. If the main purpose is to use Ligustri Lucidi Fructus as medicine， it is recommended to choose Douchi Ligustri Lucidi Fructus.
