Isolation of stigmasterol and β-sitosterol from Ocimum tenuiflorum L. (Lamiaceace)

Tóm tắt

Abstract: Some of the extracts were got from Ocimum tenuiflorum L. (Lamiaceace) by soaking and liquid-phase extraction such as n-hexane, chloroform, ethyl acetate and methanol extracts. The aim of this study is to isolation the compound in n-hexane extract from the aerial parts of the plant and then identify and characterize its structure. The isolation and purification afforded white needle-like crystals which were characterized on the basis of spectral data (IR, ¹H‐NMR, ¹³C‐NMR and HSQC) and in comparison with literature data. The compound was concluded as a mixture of stigmasterol and β‐sitosterol.

Keywords: Ocimum tenuiflorum L., stigmasterol, β‐sitosterol, extracts.
