Chinese medicinal material from Fritillaria， Beimu in Chinese， is a commonly used antitussive and expectorant traditional Chinese herbal medicine， with the significant functions of clearing heat and moistening lung，resolving phlegm and relieving cough. Five kinds of Fritillaria were recorded in the 2020 edition of Chinese Pharmacopoeia， including Fritillariae Cirrhosae Bulbus， Fritillariae Ussuriensis Bulbus， Fritillariae Thunbergii Bulbus， Fritillariae Hupehensis Bulbus and Fritillariae Pallidiflorae Bulbus. At present， the reports on Fritillaria mainly focus on the pharmacological effect， chemical composition， identification of authenticity and other aspects， while there were few reports on harvesting and primary processing of original medicinal materials. Fritillaria medicines were perennial medicinal plant with various and complex varieties， their quality and curative effect were greatly affected by harvesting and processing in producing area. The processing method differed according to its variety. Fritillariae Cirrhosae Bulbus mainly from western Sichuan plateau， Fritillariae Pallidiflorae Bulbus from Xinjiang and Fritillariae Ussuriensis Bulbus from Northeast China were mostly harvested from June to July and sun dried directly or dried. But Fritillariae Thunbergii Bulbus and Fritillariae Hupehensis Bulbus from Yangtze River basin were harvested when the plants wilted at the beginning of summer， and auxiliary materials such as shell powder and lime must be added during the processing. At present， the drying methods of Fritillaria were still traditional， which is not suitable for large-scale production of cultivated products. Therefore， it is urgent to find a scientific， reasonable and efficient processing methods. Aimed at providing references for standardization production of Fritillaria， this paper made a textual research on the ancient and modern herbal literature， the Chinese Pharmacopoeia and other medicinal standards， combined with modern literature， the harvesting and processing methods of Fritillaria were sorted out and prospected.

OBJECTIVE To establish the quality standard of Clinopodium gracile. METHODS Ten batches of C. gracile were collected to perform appearance and property identification， microscopic identification and thin layer chromatography （TLC） identification. Moisture， total ash， acid-insoluble ash and dilute ethanol extract were detected， and the content of rosmarinic acid was determined by HPLC. RESULTS The stem of C. gracile was slender， square columnar， covered by white fluff， the surface was grayish green or greenish brown； epidermal cells， non-glandular hairs， cortical cells and so on were seen in the cross section of the stem. Non-glandular hairs， ducts， wood fibers， mesophyll cells and so on could be seen in the powder. Results of TLC identification showed that there were spots of the same color in the chromatographic position corresponding to the chromatographic position of buddlejasaponin Ⅳb control. The contents of water， total ash， acid-insoluble ash， dilute ethanol extract and rosmarinic acid in 10 batches of samples were 8.69%-12.33%， 5.96%-13.33%， 0.14%-3.29%， 18.57%-32.61%， 0.35%-0.82%， respectively. The average values were 10.10%， 9.73%， 1.06%， 23.54% and 0.56%， respectively. CONCLUSIONS The established method can be used for quality control of C. gracile. It is preliminarily proposed that the ash content in the herb should not exceed 12.0%， the total ash content should not exceed 12.0%， the acid-insoluble ash content should not exceed 1.5%， the dilute ethanol extract should not be less than 18.0%， and the rosmarinic acid content should not be less than 0.45%.
