[Study on naphthopyrone reference extract and application on assay of Semen Cassiae].[Pubmed:29192451]
Zhongguo Zhong Yao Za Zhi. 2017 Sep;42(17):3385-3390.
A quality control method of Semen Cassiae was established by using naphthopyrone reference extract(NRE). Meanwhile, the feasibility about NRE replacing single component reference in quality control of traditional Chinese medicine was explored. After NRE of Semen Cassiae being prepared by chromatographic separation technology, we determined the three main components, cassiaside B2, rubrofusarin-6-O-beta-D-gentiobioside and Cassiaside C. In the meantime, an HPLC analytical method, based on the NRE as standard substance, was developed to determinate the contents of three main components in Semen Cassiae. T-test was used for comparison of the determination results of the two methods(single chemical component and NRE as reference substances, respectively), and the T-test result demonstrated that there was no significant difference between the two methods. The results developed scientific basis for the application of NRE of Semen Cassia in the quality control, which could be applied for the quality control of traditional Chinese medicine using reference extract substituting single chemical reference, and provide a new research model for the quality control of Chinese medicine.
Total synthesis of the antiallergic naphtho-alpha-pyrone tetraglucoside, cassiaside C(2), isolated from cassia seeds.[Pubmed:12895065]
J Org Chem. 2003 Aug 8;68(16):6309-13.
Toralactone 9-O-beta-d-glucopyranosyl-(1-->6)-beta-d-glucopyranosyl-(1-->3)-beta-d-glucopyran osyl-(1-->6)-beta-d-glucopyranoside (1, Cassiaside C(2)), isolated from Cassia obtusifolia L. and showing strong antiallergic activity, was concisely synthesized employing glycosyl trifluoroacetimidates as glycosylation agents. The unique naphtho-alpha-pyrone structure of toralactone (5) was constructed by condensation of orsellinate 8 with pyrone 9 in the presence of LDA as developed by Staunton and co-workers. The naphthol of toralactone showed minimal reactivity as an acceptor and was screened with various glycosyl donors. It is finally concluded that sacrifice of an excess amount of the trifluoroacetimidate or trichloroacetimidate donors (6f/6g, 6.0 equiv) in the presence of a catalytic amount of TMSOTf (0.05 and 0.3 equiv, respectively) afforded excellent yields of the coupling product, which was otherwise only a minor product under a variety of conditions examined.
