Abstract：To build the basis for its development and utilization, several kinds of plants that grow in tidal mudflats of yellow river have been selected and researched on their lipid classes with quantitative analysis. Compared with other methods, the testing method of lipid classes’ content that is commonly used in the Ramie Criteria at present is limited when it is applied directly to other natural plants, as some materials’ lipid classes have gained weight during the process of dissolving and extracting. Therefore a new method that can be widely used is proposed. First, wrap the crushed plants in the bolting cloth with #200 mesh screen, after extracting them with Carbon tetrachloride & alcohol in Soxhletsextractor, distill the extracting liquid, then have the residue dried and weighed. The result gained from this is more accurate.
