Structure Identification:
Chinese Traditional & Herbal Drugs, 2015 , 46 (10) :1426-30.
Chemical constituents from roots of Ailanthus altissima[Reference: WebLink]
To study the chemical constituents from the roots of Ailanthus altissima.
METHODS AND RESULTS:
Compounds were isolated and purified by silica gel column chromatography and HPLC, and their structures were identified by spectral analysis. Fourteen compounds were isolated and identified as 20-hydroxydammar-24-en-3-one (1), β-sitosterol (2), ocotillone (3), 5,6,7,8-Tetramethoxycoumarin (4), niloticin (5), isofouquierone peroxide (6), 20S,24S-dihydroxydammar-25-en-3-one (7), piscidinol A (8), eichlerianic acid (9), dihydroniloticin (10), dammar-24-ene-12β,20β-diol-3-one (11), canthin-6-one (12), 12β-hydroxy ocotillone (13), and 20S,25-epoxy-24R-hydroxy-3-dammaranne (14).
CONCLUSIONS:
Compounds 3, 4, 6, 9, 10, and 13 are isolated from this plant for the first time.
