[Discussion on traditional Chinese medicine properties of Myrtus communis leaves based on literature analysis and Chinese medicine theory].

Myrtus communis is a traditional medicinal aromatic plant in the Mediterranean. At present, the plant has been introduced and cultivated in the southern part of China, and it is mostly used for ornamental or cosmetic purposes. Based on literature analysis and the theory of Chinese medicine, we discussed the medicinal parts and properties of M. communis in this paper to provide a theoretical basis for exploring the medicinal value of M. communis and its compatibility with traditional Chinese medicines. Literatures were searched from Web of Science(core collection), PubMed, CNKI, VIP and Wanfang by using the set conditions as key words. Then the obtained literatures were screened and classified. Finally, a total of 376 articles were included, consisting of 44 reviews, 54 germplasm resources, 78 chemical researches, 48 studies on application, extraction, or quality, 18 human trials, 132 pharmacological studies, and 2 safety studies. Based on literature analysis and theories of Chinese medicine, the leaves of M. communis were finally selected as the medicinal part of Chinese medicine, and the traditional Chinese medicine properties of M. communis leaves were deduced as pungent, bitter, and cool. The channel tropisms of M. communis leaves included lung, liver, and large intestine, with functions of detoxifying, resolving a mass, and insecticide. It was used for mouth sores, vaginal itching, hemorrhoids and warts, etc.; appropriate amount shall be applied for external use, and the decoction form shall be used for washing the affected parts; 3-12 g equivalent product shall be used in decoction, and this herb shall be put into the decoction in a later stage. The clarification of the medicinal parts of M. communis, and the determination of the Chinese medicine properties of M. communis leaves would lay a theoretical foundation for its compatibility and application with Chinese medicines, and can do more contribution to the medical and healthcare industry in our country.

[Research progress and discussion on traditional Chinese medicine properties of Kaempferia parviflora].

Kaempferiae Parviflorae Rhizoma is the dried rhizome of Kaempferia parviflora in Zingiberaceae. It is originated and widely distributed in Thailand and other tropical and subtropical regions, where it has been used as food and medicine for thousands of years. K. parviflora is also planted in Yunnan and other places of China, but its traditional Chinese medicine properties are not clear, which greatly limits its compatibility with traditional Chinese medicines. In this article, the English and Chinese literatures of K. parviflora were searched from Web of Science, PubMed, Scopus, CNKI, Wanfang, and VIP databases for research and analysis. The medicinal properties of K. parviflora were preliminarily discussed based on the theory of traditional Chinese medicine under the guidance of clinical application and research literatures. The traditional Chinese medicine properties of K. parviflora were inferred as follows: flat, acrid, sweet. The channel tropisms of K. parviflora included kidney, spleen, stomach, and liver. The function of K. parviflora included tonifying kidney to strengthen essence, tonifying Qi and invigorating spleen, soothing liver and relieving depression. K. parviflora was clinically applied for the diseases such as syndrome of kidney essence deficiency, sex apathy, deficiency of spleen Qi, lassitude and asthenia, a weary spirit, obesity, diabetes, liver Qi stagnation, depression, and restless. The equivalent of dry power is 1.5 g·d~(-1) and the equivalent of decoction is 1.5-6 g·d~(-1). The determination of traditional Chinese medicine properties of K. parviflora has indeed laid a theoretical foundation for its application in the field of traditional Chinese medicine and enriched traditional Chinese medicine resources.

[Study on HPLC fingerprint of Herba Lysimachiae].

OBJECTIVE: To establish the chromatographic fingerprint for Herba Lysimachiae by RP-HPLC. METHODS: The sample solutions were prepared by extracting material with boiling water,followed by extracting with BuOH from the aqueous extract and analyzed by RP-HPLC with a Phenomenex C18 column (4.6 mm x 150 mm, 5 microm), gradiently eluted with A (acetonitrile containing 0.5% of acetic acid)-B (water containing 0.5% of acetic acid) at 30 degrees C, and monitored with UV detector at 255 nm. The flow rate was 1.0 mL/min, and sample volume injected was 20 microL. The chromatograms of different batches of Herba Lysimachiae were compared by the software of Similarity Evaluation System for Chromatographic Fingerprint of TCM (Version 2004A). RESULTS: HPLC Fingerprint of Herba Lysimachiae was established with Rutin as the reference compound. 13 common peaks were selected as the fingerprint peaks of Herba Lysimachiae. CONCLUSION: The established HPLC fingerprint of Herba Lysimachiae has desirable precision, reproducibility, and can be applied to routine quality control of Herba Lysimachiae.
