[Research progress on chemical constituents and quality control methods of Succus Bambusae].

Through the investigation of a large number of both domestic and overseas literatures and related quality standards, chemical compositions, quality evaluation system and quality control methods of Succus Bambusae were systematic summarized in this study. There were abundant chemical constituents in Succus Bambusae, mainly including volatile ingredients, amino acids, flavonoids, trace elements and vitamins, with high medicinal and edible value. The quality control methods involved traditional morphological identification, spectroscopy, chromatography and other techniques. However, the current quality standards of Succus Bambusae are relatively low, lacking safety indicators, and cannot effectively ensure its quality, seriously affecting the safety and effectiveness of its clinical use. Therefore, it is particularly important to establish a set of highly sensitive and specific quality evaluation system for Succus Bambusae. In this paper, the current research status of the chemical compositions and quality standards of Succus Bambusae were reviewed, with the purpose of providing a basis for further improvement of its quality evaluation system.

Herbal Textual Research and Modern Research Progress of Succus Bambusae / 中国实验方剂学杂志

Succus Bambusae， regarded as the holy medicine for the treatment of phlegm by traditional Chinese medicine experts， has the functions of clearing heat and resolving phlegm， resuscitating and relieving convulsions. In clinical practice， it is mainly used to treat phlegm-heat cough， phlegm yellow and shortness of breath， stroke with exuberant phlegm and other syndromes. The research of its processing procedure and quality standard is the key issue to realize the process modernization and quality standardization of this traditional medicine resource. On the basis of literature research， this paper conducted the herbal textual research on Succus Bambusae， sorted out its medicinal history， and compared the advantages and disadvantages of its traditional and modern preparation procedure. Based on the historical records， it is pointed out that there are still many problems in the traditional and modern processing procedure of Succus Bambusae， such as low-yield processing procedure and extensive production technology that cannot meet the requirements of large-scale green manufacturing. At present， there are a lot of literature on the comparative study of the origin， variety and processing procedure of Succus Bambusae， but most of them are limited to the chemical components， and lack of in-depth study on its pharmacodynamic substance basis and mechanism. Meanwhile， the pharmacological effects of Succus Bambusae are mostly limited to antitussive and expectorant， and few other pharmacological effects have been reported. Based on the above analysis， it is suggested that the follow-up research work can be carried out from these five aspects：①Clarifying the original source， enriching and perfecting the medicinal resources. ②Standardizing the processing procedure， establishing relevant quality standards. ③Clarifying the pharmacological mechanism， strengthening the basic research on the pharmacological effect and clinical application. ④Inheriting ancient processing， researching and developing special preparation equipment and standardizing production operation rules. ⑤Comprehensive utilization of the by-products in preparation process.

Determination of guaiacul in Succus Bambusae by HPCG / 中成药

Objective: To establish a new method for determination of guaiacul in Succus Bambusa. Methods: The contents of guaiacul were determined by HPCG with sequential increase of temperature on a HP 6890 gas chromatograph. Results: The calibration curve showcd good linearity over the range of 0 ng～47.808 ng(r=0.99995). The average recovery was 99.64% and the relative standard deviation was 2.1%(n=6). Conclusion: The method is simple, and accurate with a good reproducibility and can be used as quantitative analysis method for Succus Bambusae.
