Abstract

Abstract:

The compounds in lavender (Lavandula angustifoli) flowers in Xinjiang were extracted with supercritical CO2 extraction, isolated by various column chromatography and identified by spectroscopic methods. Finally nine compounds were isolated and further identified as betulinic acid (Ⅰ),β-sitosterol (Ⅱ),β-daucosterol (Ⅲ), cholesterol (Ⅳ), scopoletin (Ⅴ), linalool (Ⅵ), linalyl acetate (Ⅶ), steraric acid (Ⅷ), methyl stearate (Ⅸ). Especially compound Ⅳ was firstly isolated from Labiate, and compounds Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅷ and Ⅸ were firstly isolated from lavender.

Key words: lavender, supercritical fluid extraction, coumarin, steroid, triterpene
