Quality Evaluation of Atractylodis Macrocephalae Rhizoma in Different Production Methods Based on Traditional Traits / 中国实验方剂学杂志

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Herbal Textual Research on Farfarae Flos in Famous Classical Formulas / 中国实验方剂学杂志

By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.

Herbal Textual Research on Rhapontici Radix in Famous Classical Formulas / 中国实验方剂学杂志

This article systematically sorted out and researched the name， origin， harvesting and other aspects of Rhapontici Radix by referring to ancient materia medica， medical books and prescription books， combined with modern literature， in order to provide a reference basis for the development of the famous classical formulas containing this herb. According to the results of the herbal textual research， it can be seen that all the generations of the materia medica have taken Loulu as the proper name， and there are also aliases such as Luligen， Laowenghua and Jiahao. The mainstream base of Rhapontici Radix recorded in the past dynasties was the present Compositae plant Rhaponticum uniflorum， which is mostly used as medicine with roots. Since the Tang dynasty， the stems and leaves of Siphonostegia chinensis have been used as Rhapontici Radix in the northern region. Until modern times， Qizhou Pharmacognosy began to differentiate it into two categories， Qizhou Loulu and Yuzhou Loulu， according to the commodity circulation at that time， producing area and origin， of which Yuzhou Loulu is the roots of Echinops latifolius， a plant of Compositae family. In ancient times， the quality of Loulu was based on "the one that comes out of Shanzhou is the best". However， in modern times， the quality of Qizhou Loulu is better if the surface is black， neat， sturdy， firm， not broken， and without a withered heart， while the quality of Yuzhou Loulu is better if the branches are thick and long with an earthy-brown surface， solid texture and neat in length. In ancient times， most of the harvesting and processing of Loulu was "harvesting the roots in lunar August and drying them in the shade"， while in modern times， the roots are mostly excavated in the spring and autumn， and dried in the sun. Its ancient method of processing is to mix and steam with licorice， nowadays， it is prepared by removing impurities， washing， moistening thoroughly， cutting into thick slices and drying in the sun， and then taking the raw products as medicine. Based on the research conclusion， it is suggested that when developing and utilizing the famous classical formulas containing Loulu， the background of the formula should be verified， and if the original formula indicated the requirement of processing， it should be processed according to the requirement， but if not， it is recommended to use raw products as medicine.

Herbal Textual Research on Mume Flos / 中国实验方剂学杂志

Mume Flos is a traditional Chinese medicinal material，with the effects of soothing the liver，resolving phlegm and dispelling stagnation. It was mainly used to treat globus hystericus，liver and stomach pain，loss of appetite，dizziness and scrofula. Mume Flos is native to China，with a long history of cultivation and application and complex and diverse varieties. There are hundreds varieties of Mume Flos，including fruiting Mei and flowering Mei. However，there was no ancient literature on which color of Mume Flos is the best traditional Chinese medicinal material among those with different colors，as well as relevant study report on the correlation between medicinal Mume Flos group and plant systematics. In order to define the origin，the author conducted the textual research on the changes in the origin，quality and producing areas of the Mume Flos in the past dynasties. According to the findings， traditional medicinal Mume Flos were mainly green calyx Mume Flos and white Mume Flos，and derived from flowering Mei of the true Mume branch. Among them， green calyx Mume Flos belonged to the green calyx group， while medicinal white Mume Flos belonged to the albo-plena group and the single-lobe group. The producing area of Mume Flos was first recorded in Sheng Nong's Herbal Classic，where now in southern Shaanxi province. After the Song dynasty，due to climate，social and economic factors，the producing areas of Mume Flos had continued to move southward from Shaanxi province to the Yangtze River and Dongting Lake basins. Till the Ming and Qing dynasties，the distribution of Mume Flos was also reported in Guangdong province and Hainan province. In modern times，due to the comprehensive impact of natural climate conditions and urbanization，the producing areas of medicinal Mume Flos had gradually changed from Sichuan province，Jiangsu province and Zhejiang province to southern Anhui province at present. In this paper，the textual research is conducted to define the origin and systematically summarize the changes in the producing areas of Mume Flos，so as to provide reference for defining the origin of Mume Flos and the groups of medicinal Mume Flos and making further development and utilization of resources.

Herbal textual research on Rubi Fructus / 中国中药杂志

Rubi Fructus is a commonly used traditional Chinese medicine. The origin of Rubi Fructus is the dried fruit of Rubus chingii, a plant of the family Rosaceae, according to the 2015 edition of Chinese pharmacopoeia. There are some differences in the plant origin of Rubi Fructus in ancient herbal literature, to trace back its sources, we conducted a textual research on its origin, producing areas, quality evaluation, processing and concocting, properties, tastes and efficacy etc. based on the records of ancient herbal literatures and combined with plant morphology and related investigation. RESULTS:: showed that the variety of Rubi Fructus was more complex among ancient herbal literature, including R. coreanus, R. hirsutus, R. corchorifolius, R. foliolosus and other mixed varieties. Most scholars believe that the R. chingii has not been recorded in ancient herbal literature, while R. chingii was recorded as early as the Ming Dynasty in Compendium of materia medica through our textual research. Ancient Chinese herbs recorded that Rubi Fructus was mostly produced in Hubei, Shandong, Shanxi and Jiangsu provinces, while R. chingii mainly produced in Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian and other provinces nowadays. Also, it was recorded that Rubi Fructus harvested in wheat field during May were the best. Besides, R. chingii with big, full, grain integrate, firm, yellow and green color, sour taste and impurity free possess the best quality in the contemporary. The ancient records of processing and concocting, properties, tastes and efficacy were basically the same as modern ones.These results provide the basis for the correct utilization and further development of Rubi Fructus.

Decipherment of herb medicine Nanwuweizi and Wuweizi in Chinese ancient literature / 中国中药杂志

Nanwuweizi( Schisandrae Sphenantherae Fructus) and Wuweizi( Schisandrae Chinensis Fructus) have long-term history of use as common traditional Chinese medicines since the Eastern Han Dynasty( AD.25-220 year).However their information are always confused in ancient literature because they were both used as " Wuweizi". Nanwuweizi and Wuweizi are faced with problems such as confused distribution of producing areas,unclear source plants and efficacy characteristics,which limit modern resource development and application. Based on ancient literatures of materia medica,this study conducted a systematic review from several aspects,i.e. the name,distribution of producing areas,source plants,efficacy characteristics and processing of the two medicines in ancient time. This study clarified five main aspects,as following,ancient production areas and corresponding modern distribution areas; source plants used for medicinal purposes in ancient time; application period and application scope; efficacy characteristics in clinical application;processing method. This study provides a reference for evaluating the quality and for their clinical application and reasonable development of Nanwuweizi and Wuweizi.

Herbal textual research on relationship between Chinese medicine"Shihu" (Dendrobium spp.) and "Tiepi Shihu" (D. catenatum) / 中国中药杂志

Dendrobium species on the ancient Chinese herbal texts were investigated in this paper, including their dscriptions of original species, producing areas and quality. Our results indicated that the major producing areas were Lu'an, Anhui province and Wenzhou, Taizhou, Zhejiang province. In addition, the sweet flavor, short, thin and solid stems were standing for good quality. Based on the stable producing areas and quality descriptions, D. catenatum (D. officinale) ("Tiepi Shihu") and D. houshanense were high quality medicinal Dendrobium species ("Shihu" ) in ancient China. Besides, there were 3 scientific names for "Tiepi Shihu", including D. candidum, D. officinale, D. catenatum. After textual investigation, We suggest that D. catenatum should be its scientific name, and D. officinale was synonyms published later. However, the name "D. officinale" could be reserved as it is much more popular used in publication and commodities. Moreover, its Chinese name should be "Tiepi Shihu".
