Comparison on Pharmacodynamics of Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from Four Different Sources on Rats with Qi Deficiency / 中国实验方剂学杂志

Objective:The effects of Atractylodes lancea， A. coreana， A. japonica， A. chinensis and Atractylodis Macrocephalae Rhizoma on spleen-Qi deficiency rats were compared. Method:A model of spleen-Qi deficiency was induced in rats by diet and overwork.The rats are given different suspensions of A.japonica， A.chinesis， A.coreana， A.lancea and Atractylodis Macrocephalae Rhizoma To test the indicators of the digestive system， immune system and antioxidant enzyme system related to spleen deficiency.Compare the similarities and differences between Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from four different sources. Result:All the drug-administered groups can increase the levels of γ interferon （IFN-γ）， gastric secrete element（GAS），serum amylase （AMS） and catalase（CAT） in rats with spleen-deficiency syndrome，in addition to the CAT index， the other indicators of the A. coreana， A.japonica， and A.lancea were significantly increased（P<0.05）. The MTL content of the A.chinesis， A.lancea， A.coreana and A.japonica increased and was significant（P<0.05）. The SDH content of A.japonica.and A.chinesis increased， and the difference was not significant.The increase of GSH-Px in the A.chinesis is significant（P<0.05）. All the drug-administered groups can reduce the content of IgG， TNF-α and MDA in rats with spleen deficiency and deficiency syndrome. Among them， the IgG content of the A.chinesis. and the A.lancea was significantly decreased（P<0.05）. The content of TNF-α in A.japonica group was significantly decreased（P<0.05）. The content of MDA in the A.chinesis， the A.lancea， the A.coreana，the A.japonica and the Atractylodis Macrocephalae Rhizoma were significantly decreased（P<0.05）.The decrease of IL-6 in the A.lancea was significant（P<0.05）. Conclusion:Four different sources of Atractylodes Rhizome and A.macrocephala have certain therapeutic effects on spleen-deficiency rats with deficiency syndrome.The therapeutic effect of A.lancea and A.japonica is basically the same，regulating the absorption，secretion and elimination of inflammation in the digestive system of rats with spleen deficiency A.coreana， A.chinesis， and Atractylodis Macrocephalae Rhizoma have certain regulatory effects in the digestive system， digestive tract inflammation， and antioxidant enzymes.

Research progress on Atractylodes japonica / 中草药

Objective Atractylodes japonica, a member of the Compositae family, is a per nnial Chinese medicinal plant, whose rhizomes are used as medicinal materials with functions of antibiosis, anti-inflammatory, and dispelling wind-cold. A. japonica is mainly distributed in northeast China, which is the genuine medicine in northeast China, and it is also a traditional medicine of Korean nationality. In this paper, the plant morphology, classification, identification of medicinal properties, chemical composition, pharmacological effects, and the cultivation techniques of A. japonica were briefly reviewed. The purpose of this paper is to provide theoretical reference for rational exploitation of Chinese material medica and sustainable utilization of resources of A. japonica.

Research of Chemical Constituents and Pharmacological Effects of Korean Medicine Atractylodes japonica / 中国药房

OBJECTIVE:To provide reference for development and application of Korean medicine Atractylodes japonica. METHODS:Using"Guancangsu""Huaxue chengfen""Yaoli zuoyong""Atractylodes japonica""Chemical constituents""Pharmacological effects"as Chinese and English key words,relevant literatures published during 1983-2017 were retrieved from CNKI, PubMed, ScienceDirect full-text database, the chemical constituents and pharmacological effects of A. japonica were reviewed. RESULTS & CONCLUSIONS:As of June 21,2017,a total of 226 literatures were collected,including 43 valid literatures. A. japonica mainly contains terpenoids,aliphatic,aromatic in volatile oil,glycosides active constituents in roots,and shows anti-inflammatory and analgesic,cardio cerebral vascular protection,contianaphylaxis,antibacterial,antiviral and anti-ulcer effects. Currently,the research of A. japonica on the chemical constituents and pharmacological effects has achieved initial results, however, reports of its toxicity are rare. Therefore, the safety evaluation should be taken into account in the study of its pharmacological effects.

The Effects of an Extract of Atractylodes Japonica Rhizome, SKI3246 on Gastrointestinal Motility in Guinea Pigs

BACKGROUND/AIMS: There are limited therapeutic options available for irritable bowel syndrome with diarrhea (IBS-D). We tested the effects of Atractylodes japonica rhizome, a perennial plant native to North Asia, on both upper and lower gastrointestinal (GI) motility in guinea pigs. METHODS: The extract of A. japonica rhizome was administered orally at different doses to test its effects on upper GI motility as determined from charcoal transit in native guinea pigs and in guinea pigs pretreated with thyrotropin-releasing hormone or mustard oil. Regarding its effect on lower GI motility, the removed guinea pig colon was suspended in a chamber containing Krebs-Henseleit solution and the transit time of artificial feces was measured with various dilutions of the extract. As for in vivo assay, weight and number of fecal pellets expelled were determined under the same drug preparation used in upper GI motility experiment. RESULTS: The extract of A. japonica rhizome had no significant effect on upper GI motility in either normal or altered physiological states. However, the extract increased colonic transit time in the in vitro model. In the fecal expulsion study, the cumulative weight and number of pellets did not differ significantly between the control group and groups treated with the extracts. In the animals pretreated in vivo with thyrotropin-releasing hormone, however, the weight and number of fecal pellets were significantly decreased in animals treated with 300 mg/kg and 600 mg/kg doses of extract. CONCLUSIONS: Our findings suggest that the extract of A. japonica rhizome can be a potential agent for IBS-D.

A Study of the Differences in the Clinical Use of Atractylodes Japonica and Atractylodes lancea in Kampo Formulas / 日本東洋医学雑誌

In the classical Oriental medical texts the “Shang Han Lun” and the “Jin Kui Yao Lue”, no clear distinction is made between Atractylodes japonica and Atractylodes lancea. Even today, no sharp critical distinction is made between the usage of these crude drugs in Kampo formulas. The authors have attempted to elucidate the differences in their clinical effect by investigating the way patients reacted when the two crude drugs were interchanged in Kampo formulas the patients were taking.<br>It was found that Atractylodes lancea was more effective than Atractylodes japonica for patients with arthralgia. Of the effective cases, 60% reported that the formula had a pleasant taste, while 9% reported it tasted bad. This suggested that taste may play a significant role in patient's responses to Kampo formulas.
