Two new sesquiterpene polyol esters from the root barks of Celastrus angulatus.[Pubmed:21462033]
J Asian Nat Prod Res. 2011 Apr;13(4):304-11.
Angulatin F (1) and angulatin I (2), two new sesquiterpene polyol esters, were isolated from the root barks of Celastrus angulatus, together with six known compounds 1beta,2beta-diacetoxy-4alpha,6alpha-dihydroxy-8alpha-isobutanoyloxy-9beta-benzoyloxy-15-(alpha-methyl) butanoyloxy-beta-dihydroagrofuran (3), angulatin A (4), Angulatin B (5), celangulatin E (6), 1beta,2beta,15-triacetoxy-4alpha,6alpha-dihydroxy-8alpha-isobutanoyloxy-9beta-benzoyloxy-beta-dihydroagrofuran (7), and celangulin I (8). The structures of 1 and 2 were elucidated as 1beta,2beta,6alpha,15-tetraacetoxy-4alpha-hydroxy-8beta,9alpha-difuroyloxy-beta-dihydroagrofuran and 1beta,2beta,6alpha,8beta,15-pentaacetoxy-4alpha-hydroxy-9beta-furoyloxy-beta-dihydroagrofuran by spectroscopic means.
[Assignments of 1HNMR fingerprint of the root bark of Celastrus angulatus].[Pubmed:12585134]
Yao Xue Xue Bao. 2001 Jun;36(6):462-6.
AIM: To assign the 1HNMR finger-print of the root bark of Celastrus angulatus. METHODS: Silica gel column chromatography was used to separate the chemical constituents of CGE A of the root bark of C. angulatus. The characteristic signals of the 1HNMR finger-print were assigned after determining the structures of the compounds isolated from CGE A. RESULTS: 1HNMR finger-prints of the samples of C. angulatus collected from different regions showed highly characteristic features and reproducibility. Three compounds predominant in CGE A were isolated and their structures were determined by spectral analysis as: angulatin A (1), Angulatin B (2) and angulatin C (3). CONCLUSION: Compound 3 is a new compound. Compound 2 was isolated from C. angulatus for the first time. The 1HNMR finger-print of CGE A of the root bark of C. angulatus showed mainly the characteristic signals of the above three compounds and might be utilized for the original authentication of this plant.
