Isolation of the isopropanol extract components of the leaves of Ailanthus glandulosa by a new method

Abstract

The leaves of Ailanthus glandulosa were extracted with the Soxhlet apparatus using isopropanol. A new method was used to separate and isolate eleven chemical compounds present in the leaves of bird's tongue. The separation was carried out by column chromatography using displacement solvents (petroleum ether, chloroform, dichloromethane, methanol) and four eluates were obtained. The four eluates were treated with a number of solvents, yielding thirty-four compounds. The chemical content of the mordants was determined using GC/MS technology. The samples tested contained six ester compounds, three aldehyde compounds, three ketone compounds, two alcoholic compounds, eight carboxylic acid compounds, five silicone compounds, five aromatic compounds and one phosphate compound.Eleven compounds were isolated, the most important of which are: 2-naphthoxyacetic acid, 2,6-bis (1,1-dimethylethyl)-4-ethylphenol, 2,5-tert-butylnitrobenzene, 5-hexyl-2-furaldehyde, 16-nitrobicyclo [10.4.0] hexadecan-1-ol-13-one, cyclooctasiloxan hexadecamethyl.
