Study on quality transfer law of Magnoliae Officinalis Cortex in processing based on nine components determination / 中草药

Objective: To reveal the scientific connotation of ginger-processed Magnoliae Officinalis Cortex (MOC), and standardize the production process and offer the theoretical base for clinical medication. Methods: This paper studied on quality transfer law of MOC in processing based on the determination of nine chemical components, including syringing, magnocurarine, magnolin B, magnoflorine, magnolin A, honokiol, magnolol, piperitylmagnolol, and β-eudesmol, through controlling factors such as part of sample collection, processing technology, personnel, equipment and environment. Results: The results showed that the content of phenolic components was increased slightly, the content of alkaloids was decreased significantly, and the content of glycosides was decreased, and the content of magnoloside B was decreased significantly in the process of preparation for MOC and ginger-processed MOC. Moreover, there was no significant difference in the content of magnoloside A, syringin, and volatile oil represented by β-eudesmol. Conclusion: This study preliminarily explored the quality transfer law of multi-components in the processing of MOC, and provided reference for the establishment of the quality control system of the crude drug processing technology and improvement of the quality of products.

Chemical constituents of Caulophyllum robustum and its antitumor activities / 中草药

Objective To study the chemical constituents of Caulophyllum robustum and its antitumor activities. Methods The chemical constituents were isolated and purified with silica gel column chromatography, dextran gel Sephadex LH-20, and other chromatographic methods. Their structures were determined by physicochemical and spectral analysis. Furthermore, the cytotoxicity of these chemical components against the NSCLC A549 cell line was measured by CCK-8 method. Results Eleven compounds were isolated and identified as collinsogenin (1), hederagenin (2), eechinocystic acid 3-O-α-L-arabinopyranoside (3), magnolamide (4), (-)-magnocurarine (5), columbamine (6), 4,4’-diphenylmethane-bis (methyl) carbamate (7), (-)-8,8’-dimethoxy-L-O-(β-D- glucopyranosyl) secoisolariciresinol (8), asechipuroside A (9), 2-[4-(3-hydroxy-1-propenyl)-2-methoxyphenoxy]-1,3-propanediol (10), and 1-linoleoylglycerol (11). Conclusion Compounds 1-2 and 4-11 are isolated from Caulophyllum robustum genus for the first time. Compounds 1 and 2 show moderate inhibited effect on the proliferation of NSCLC A549 cell line.

Identification of Chemical Constituents in Magnoliae Officinalis Cortex by UFLC-Triple TOF-MS/MS / 中国药学杂志

OBJECTIVE: To qualitatively analyze the major chemical constituents of Magnoliae Officinalis Cortex by UFLC-Triple TOF-MS/MS. METHODS: The analysis was carried out on an Agilent ZORBAX SB-C18 column(4.6 mm ×250 mm, 5 μm)with gradient elution of 0.1% formic acid-acetonitrile under both positive and negative ionization modes of ESI, respectively. The chemical components of Magnoliae Officinalis Cortex were identified by analyzing the accurate mass of molecular and product ions provided by UFLC-Triple TOF-MS/MS, comparison with reference standards and the literature data. RESULTS: A total of 24 compounds were identified or tentative presumed in Magnolia Officinalis Cortex, including 12 lignans, 9 alkaloids, and 3 phenylpropanoid glycosides. CONCLUSION: This study provides the foundation and support for study on material foundation of efficacy and the overall assessment of quality of Magnoliae Officinalis Cortex.
