Abstract

The invention discloses a method for determining squalene content of pandanus amaryllifolius Roxb. volatile compositions. HPLC is employed for determination. The mobile phase is methanol, the flow velocity is 0.8-1.2 mL / min, the detection wavelength is 204 nm, the column temperature is 25-35 DEG C, the detection time is 30 min, and the sample size is 10 mu L. By using the method for determining squalene content from pandanus amaryllifolius Roxb. volatile compositions, the sample size and the peak area integral value show a good linear relation, the sample stability, the instrument precision, the method reappearance and the method specificity all accord with requirements, and a basis is established for rapid and accurate quantification of squalene.

Description

technical field [0001] The invention relates to the technical field of chemical analysis, in particular to a method for determining the content of squalene from the volatile components of the pandanus. Background technique [0002] Pandanus leaves are the fresh leaves of Pandanus amaryllifolius Roxb (Pandanus amaryllifolius Roxb). Xiangludou is an evergreen herb, the leaves are about 30cm long and 1.5cm wide, with occasional thorns on the leaf margins, slightly dense thorns on the leaf tips, slightly thorns on the apex of the back of the leaves, a narrow white film on the leaf sheath, and no flowers and fruits. The origin is Maggulu Islands, Indonesia. Studies have found that Pandanus is suitable for the acidic red soil in southern my country, but due to temperature restrictions, it is only suitable for growing in the southern subtropical zone to the tropical region of my country. [0003] Carrageenan is a natural chain triterpene compound and an important natural active s...
