ABSTRACT
As a traditional Chinese medicinal material， Citri Sarcodactylis Fructus is often used as medicine after steaming to reduce its pungency and give full play to its medicinal effects. By consulting the relevant literature， this paper intends to sort out the related researches on the processing history， modern processing standard records， flavor and meridian tropism， efficacy， processing and taking methods， processing technology， chemical composition， pharmacological effects and quality analysis of Citri Sarcodactylis Fructus. It is found that the processing methods of Citri Sarcodactylis Fructus in the past dynasties are mainly roasting， distilled into dew， aging， frying， salting and steaming， of which steaming is the most common. In modern times， steaming is mainly used in Guangdong and Sichuan. The descriptions of flavor and meridian tropism and efficacy of Citri Sarcodactylis Fructus in the past dynasties are basically consistent with the modern descriptions. Its taste is pungent， bitter and acidic， and it is warm in nature. It belongs to the liver， spleen， stomach and lung meridians. Citri Sarcodactylis Fructus contains volatile oil， flavonoids and their glycosides， coumarins and limonins and other compounds. In recent years， high performance liquid chromatography （HPLC）， gas chromatography-mass spectrometry （GC-MS） and ultra performance liquid chromatography-mass spectrometry （UPLC-MS） and other methods are commonly used for the chemical composition analysis. Citri Sarcodactylis Fructus has the activities of relieving cough， reducing phlegm， relieving asthma， anti-inflammation， anti-bacteria and anti-oxidation， etc. After processing， its volatile and non-volatile components， and pharmacological effects all have a certain change. However， the current research on processing of Citri Sarcodactylis Fructus is not in-depth enough. It is necessary to further analyze the material basis of steaming to reduce dryness， explore its dryness medicinal substances and dryness-effect quantitative correlation， so as to clarify its processing mechanism， and provide basis for the subsequent processing research， resource development and comprehensive application of Citri Sarcodactylis Fructus in the future.

ABSTRACT
Citri Sarcodactylis Fructus, a traditional Chinese medicine with dual-purpose of drug and food, has a long history of cultivation and application, showing high medicinal, dietetic, ornamental and economic values. Many modern researches have been conducted on the extraction technology, chemical constituents, quality standards and biological activities, but the herbal textual researches were relatively insufficient. The related records of Citri Sarcodactylis Fructus in the ancient Chinese medicinal classics were ambiguous and confusing. By referring to ancient Chinese medicinal classics and modern books, the textual researches of Citri Sarcodactylis Fructus, including the names, plant morphology, origin, medicinal properties, efficiency and application were systematically reviewed and analyzed in this paper, in order to provide the basis for the confirmation of original source of Citri Sarcodactylis Fructus. The results showed that Citri Sarcodactylis Fructus was usually recorded as ‘Xiangyuan’ ‘Juyuan’ ‘Ganyuan’ ‘Xiangyuan’ ‘Foshougan’ etc. in ancient books. After the Ming and Qing dynasties, it became clear that ‘Xiangyuan’ was equivalent to ‘Juyuan’, but different from ‘Foshougan’. Therefore, these two species were recorded separately. From the ancient times to the present day, Citri Sarcodactylis Fructus was always mainly distributed in south of the Yangtze River, such as Fujian, Guangdong, Guangxi, and Jiangxi provinces. Ancient records and modern reports basically have the same understanding on properties, efficacies and indications of Citri Sarcodactylis Fructus, considering it was warm in nature with the effectiveness of soothing liver, relieving pain, eliminating dampness and resolving phlegm. ‘Baking it into powder on new tiles’ and ‘steaming’ were the traditional processing methods. The description of ‘The longer of storage period, the better of the effect’ was occasionally recorded. These results provide theoretical references for the further study, resource development and comprehensive application of Citri Sarcodactylis Fructus.
