The present application relates to extracting a plurality of compounds from a traditional Chinese medicine, or synthesizing a compound capable of promoting nucleic acid delivery, and utilizing the extracted compound, or a plurality of combinations to promote absorption and entry of a nucleic acid such as sRNA into a target cell, and to facilitate the entry of a nucleic acid into a target site in a subject in need thereof.

Disclosed are preparation of zinc linolenate, and application thereof in preparing an anti-Helicobacter pylori drug. Zinc chloride is dissolved in sterile water, and the zinc chloride solution is heated and activated in a reactor kettle, and then naturally cooled to room temperature; 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, N-hydroxysulfosuccinimide sodium salt and linolenic acid are dissolved in an EMS solvent and activated in nitrogen gas; the activated zinc chloride and the activated linolenic acid are heated and reacted, then left for standing after the reaction is finished; a dialysis bag is used to perform dialysis in pure water until the pure water is clear and transparent; and a vacuum freeze dryer is used to perform drying, and zinc linolenate is obtained. The present invention successfully prepares zinc linolenate, with high yield, and the zinc linolenate has a good Helicobacter pylori inhibiting effect.

Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.
