    Description: 7-O-Methylaloeresin A shows significant antioxidant activity, it also has moderate inhibitory active on BACE. 7-O-Methylaloeresin A exhibits 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.
    Targets: BACE
    In vitro:

    In vitro antimicrobial and antioxidant activities of anthrone and chromone from the latex of Aloe harlana Reynolds.[Pubmed: 21452374]
    Anthrone (aloin) and chromone (7-O-Methylaloeresin A).
    METHODS AND RESULTS:
    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.
    CONCLUSIONS:
    These findings support the traditional uses of the plant for the treatment of various infectious and inflammatory diseases.
    7-O-Methylaloeresin A Description
    Source: The herbs of Aloe arborescens Mill.
    Solvent: DMSO, Pyridine, Methanol, Ethanol, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day.

    Active constituents from Aloe arborescens as BACE inhibitors.[Pubmed: 17184120]
    To seek for new components as BACE inhibitors from Aloe arborescens.
    METHODS AND RESULTS:
    The chemical constituents were isolated by chromatographic methods and their structures were elucidated on the basis of spectral analysis. 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.
    CONCLUSIONS:
    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.
