Abstract

The invention relates to a method for determining content of sterol and / or derivatives thereof by utilizing a quantitative nuclear magnetic resonance technology. The method comprises the following steps: adopting a nuclear magnetic resonance internal standard method, selecting a specific quantitative peak of sterol and / or derivatives thereof, and accurately determining (total) content of the sterol and / or derivatives thereof. The method provided by the invention has the advantage that extracts of animals, plants and / or microorganisms, food, medicines or the content of sterol and / or derivatives thereof in cosmetics can be accurately determined.

Description

technical field

[0001] The invention provides a method for determining the content of sterols and / or derivatives thereof by using hydrogen nuclear magnetic resonance spectroscopy. Background technique

[0002] Sterols and their derivatives include natural and synthetic sterols and their derivatives. Natural sterols and their derivatives include plant and animal sterols and their derivatives. Among them, phytosterols (plant sterols) are a class of natural alcohol compounds with cyclopentane perhydrophenanthrene (steroid nucleus) as the skeleton, and are one of the components of cell membranes in plants. The structure of this type of compound is similar to that of cholesterol, and has the functions of lowering cholesterol and preventing and treating cardiovascular diseases. It is a kind of safe and effective natural phytochemicals. In 1999, the U.S. Food and Drug Administration (FDA) has approved the use of "healthy" labels for foods added with phytosterols. In 2000, the U....
