Since 2016, a number of studies have been published on standard decoctions used in Chinese medicine. However, there is little research on statistical issues related to establishing the quality standards for standard decoctions. In view of the currently established quality standard methods for standard decoctions, an improvement scheme is proposed from a statistical perspective. This review explores the requirements for dry matter yield rate data and index component transfer data for the application of two methods specified in “Technical Requirements for Quality Control and Standard Establishment of Chinese Medicine Formula Granules,” which include the average value plus or minus three times the standard deviation (X-±3SD) or 70% to 130% of the average value (X-±30%X-). The square-root arcsine transformation method is used as an approach to solve the problem of unreasonable standard ranges of standard decoctions. This review also proposes the use of merged data to establish a standard. A method to judge whether multiple sets of standard decoction data can be merged is also provided. When multiple sets of data have a similar central tendency and a similar discrete tendency, they can be merged to establish a more reliable quality standard. Assuming that the dry matter yield rate and transfer rate conform to a binomial distribution, the number of batches of prepared slices that are needed to establish the standard decoction quality standard is estimated. It is recommended that no less than 30 batches of prepared slices should be used for the establishment of standard decoction quality standards.

Objective:There were 92 kinds of compound preparations containing Ophiopogonis Radix in the 2015 edition of Chinese Pharmacopoeia， but there was no effective method to identify these compound preparations. Because Ophiopogonis Radix and Liriopes Radix are similar in appearance， it is easy to be confused in application. The aim of this study was to set up a thin layer chromatography （TLC） to identify compound preparations containing Ophiopogonis Radix and distinguish Ophiopogonis Radix and Liriopes Radix in the forms of decoction pieces and standard decoction. Method:In this study， decoction pieces of Ophiopogonis Radix and Liriopes Radix were collected and separately prepared as standard decoction. TLC was used to qualitatively identify decoction pieces and standard decoction of Ophiopogonis Radix and Liriopes Radix， and compound preparations containing Ophiopogonis Radix. In the TLC， the lower solution of chloroform-methanol-water （65∶35∶10） was selected as the developing agent and 10% sulfuric acid ethanol solution as the chromogenic agent. Result:The resolution of this TLC was good. Decoction pieces， standard decoction and preparations of Ophiopogonis Radix had the same characteristic strips， which were two bright white fluorescent strips under ultraviolet lamp （365 nm）. But these two characteristic strips were not existed in the TLC of decoction pieces and standard decoction of Liriopes Radix. The corresponding components of both of these two strips were identified as mixture containing saponins by LC-MSn， including ophiopogonin Ra， Tb， ophiopogonin D'， borneol glycoside， ophiopogonin C and Liriope muscari baily saponins C. Conclusion:The established TLC method， which has significant advantages such as high specificity and sensitivity， can be applied to the characteristic identification of decoction pieces and standard decoction of Ophiopogonis Radix， the identification of compound preparations containing Ophiopogonis Radix， and the distinction of Ophiopogonis Radix and Liriopes Radix， thus serving as an effective method to qualitatively identify Ophiopogonis Radix and its compound preparations.

OBJECTIVE: To prepare Cinnamomi Ramulus standard decoction according to the traditional decoction method, and study the preparation process and quality control of Cinnamomi Ramulus formula granules. METHODS: The standard decoctions of 16 batches of Cinnamomi Ramulus were prepared using decocting pot. The extracting rate, contents and transfer rates of cinnamic acid and cinnamaldehyde were calculated. The preparation process of Cinnamomi Ramulus dispensing granules was improved based on the parameters of standard decoction. The volatile oil was collected while extracting, and the β-cyclodextrin inclusion technology was applied in the granulation process. Based on the parameters of standard decoction, the quality standard of Cinnamomi Ramulus formula granules was established. RESULTS: The extracting rate of Cinnamomi Ramulus standard decoction was 3.58%-6.10%; the cinnamic acid content was 0.99%-2.59% and the transfer rate was 39.56%-62.28%; while the cinnamaldehyde content was 1.95%-4.69% and the transfer rate was 4.76%-7.85%. According to the standard decoction, 1 g of Cinnamomi Ramulus formula granules was equivalent to 14 g of pieces, containing cinnamic acid (0.50%-1.43%) and cinnamaldehyde (0.98%-3.50%). Six characteristic peaks in specific spectra were confirmed, including protocatechuic acid (1), coumarin (2), cinnamic acid (3), 2-methoxycinnamic acid (4), cinnamaldehyde (5) and 2-methoxycinnamaldehyde (6). CONCLUSION: In this study, the quality parameters of Cinnamomi Ramulus standard decoction are determined by traditional decocting pot. The strategy of establishing the preparation process and quality standard of Cinnamomi Ramulus formula granules based on standard decoction is proposed. It can provide reference for the research of Cinnamomi Ramulus dispensing granules and other Chinese medicine preparations containing volatile oil.
Résumé
The quality evaluation method for standard decoction of Chinese herbal slices is the basis for the quality evaluation of granules and preparations of classical formula(decoction)of traditional Chinese medicine. This study aimed to establish a method for the determination of quercetin-3-O-glucuronic acid in Nelumbinis Folium(NF)and its standard decoction, so as to provide reference for the quality control of NF and its standard decoction. Fifteen batches of representative NF were collected to prepare standard decoction, and the parameters of dry extract rate, transfer rate of index component, and pH value were calculated. HPLC was used to establish the content determination method for quercetin-3-O-glucuronic acid in NF and its standard decoction. The concentration range of quercetin-3-O-glucuronic acid in the standard decoction of NF was 1.09-3.06 g·L~(-1), while the concentration range of nuciferine was 0.01-0.17 g·L~(-1). The average extraction rate of NF standard decoction was(14.4±2.6)%, the average transfer rate of quercetin-3-O-glucuronic acid was(70.7±18.6)%, and the average transfer rate of nuciferine was(9.6±5.4)%. Compared with Nuciferine, quercetin-3-O-glucuronic acid had a high content and stable transfer rate in standard decoction, and was recommended to be the quality control marker for NF and its standard decoction. This paper establishes a quality evaluation method for NF standard decoction, and can provide reference for the quality control of all preparations derived from NF and its decoction.
