7-O-methylaloeresin A--a new chromone glycoside from Commiphora socotrana
Nat Prod Lett 2001;15(1):27-33.PMID:11547420DOI:10.1080/10575630108041254.
A new 5-methylchromone glycoside, named 7-O-Methylaloeresin A (2-acetonyl-8-C-beta-D[2'-O-(E)-4-hydroxycinnamoyl]glucopyranosyl-7- methoxy-5-methylchromone, 1), was isolated from Commiphora socotrana (Burseraceae). Its structure was elucidated by spectroscopic data (MS, UV, 1H- and 13C-NMR).
Chromones and anthrones from Aloe marlothii and Aloe rupestris
Phytochemistry 2000 Dec;55(8):949-52.PMID:11140530DOI:10.1016/s0031-9422(00)00328-9.
A phytochemical investigation of the leaf exudate of Aloe marlothii has resulted in the isolation of a new chromone (7-O-Methylaloeresin A) and a new anthrone (5-hydroxyaloin A 6'-O-acetate). Furthermore 7-O-methylaloesin was isolated as a natural product for the first time from the leaf exudate of Aloe rupestris. The structure elucidation of these compounds was based on spectral data including 2D NMR. The chemotaxonomic value of 7-O-methylaloesin in Aloe series Asperifoliae and section Pachydendron is discussed.
In vitro antimicrobial and antioxidant activities of anthrone and chromone from the latex of Aloe harlana Reynolds
Phytother Res 2011 Dec;25(12):1756-60.PMID:21452374DOI:10.1002/ptr.3482.
In the search for new antimicrobial and antioxidant compounds from plants, the latex of the medicinal plant Aloe harlana Reynolds from Ethiopia was subjected to bioassay-guided fractionation, which led to the isolation of two known compounds, anthrone (aloin) and chromone (7-O-Methylaloeresin A). The latex and its two constituents were assessed for their possible antimicrobial activities against 23 bacterial and four fungal strains using the disc diffusion method and their antioxidant activity by two complementary test systems, namely 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2-deoxyribose degradation assay methods. The isolated compounds showed promising results against various pathogenic bacterial and fungal strains in comparison with standard drugs. Moreover, 7-O-Methylaloeresin A exhibited good activity against multiple drug resistant Staphylococcus aureus (NCTC 11994) and Salmonella typhimurium (ATCC 1255) with MIC values of 0.72 and 0.18 mm, respectively. Among the fungal strains tested, Candida albicans (ATCC 10231) was the most susceptible organism to the latex and the two isolated compounds. The latex and isolated compounds also showed significant activities on both antioxidant assays with the highest activity being observed for 7-O-Methylaloeresin A, which gave IC(50) values of 0.026 mm and 0.021 mm for DPPH and 2-deoxyribose degradation assay, respectively. These findings support the traditional uses of the plant for the treatment of various infectious and inflammatory diseases.
Comprehensive Identification of Chemical Fingerprint and Screening of Potential Quality Markers of Aloe vera (L.) Burm. f. from Different Geographical Origins via Ultra-High-Performance Liquid Chromatography Hyphenated with Quadrupole-Orbitrap-High-Resolution Mass Spectrometry Combined with Chemometrics
J Chromatogr Sci 2023 Mar 9;bmad009.PMID:36892173DOI:10.1093/chromsci/bmad009.
An integrated strategy was developed for the systematic chemical fingerprint and chemometrics analysis for the quality assessment of Aloe vera (L.) Burm. f. The ultra-performance liquid chromatography fingerprint was established, and all common peaks were tentatively identified by using ultra-high-performance liquid chromatography hyphenated with quadrupole-orbitrap-high-resolution mass spectrometry. Afterwards, the datasets of common peaks were subjected to hierarchical cluster analysis, principal component analysis and partial least squares discriminant analysis to holistically compare the differences. The results revealed that the samples were predicted to fall into four clusters, which were related to four different geographical locations. Using the proposed strategy, aloesin, aloin A, aloin B, aloeresin D and 7-O-Methylaloeresin A were rapidly determined to be the potential characteristic quality markers. Finally, five screened compounds in 20 batches of samples were simultaneously quantified, and their total contents were ranked as follows: Sichuan province > Hainan province > Guangdong province > Guangxi province, which suggests that geographical origins may be an important factor affecting the quality of A. vera (L.) Burm. f. This new strategy can not only be used to explore possibly the latent active substance candidates for pharmacodynamic studies, but it is also an efficient analytical strategy for other complex traditional Chinese medicine systems.
[Active constituents from Aloe arborescens as BACE inhibitors]
Yao Xue Xue Bao 2006 Oct;41(10):1000-3.PMID:17184120doi
Aim: To seek for new components as BACE inhibitors from Aloe arborescens. Methods: The chemical constituents were isolated by chromatographic methods and their structures were elucidated on the basis of spectral analysis. Results: Eight compounds were isolated and their structures identified as 6'-O-isobutyryl aloenin A (1), aloenin A (2), aloe-emodin (3), (E)-2-acetonyl-8-(2'-O-feruloxyl)-beta-D-glucopyranosyl-7-methoxy-5-methyl-chromone (4), 7-O-Methylaloeresin A (5), babarloin A (6), elgonica-dimer A (7), and elgonica-dimer B (8), separately. Conclusion: Compound 1 is a new compound, and compound 4 was isolated from A. arborescens for the first time. Pharmacological tests indicated that 2, 4, 5 and 6 have moderate inhibitory active on BACE.
