A Fraxinus excelsior seed extract that can be administered for therapeutic treatment of a subject, including a human, by blocking fat synthesis, activating PPAR-alpha, increasing hypoglycemic activity, reducing bodyweight, controlling fasting plasma insulin levels against hyperinsulinemia, and promoting insulin sensitivity and causing a beneficial acute insulinotropic effect. The Fraxinus excelsior seed extract includes, inter alia, an isolated compound (2S,3E,4S) 2H-Pyran-4-acetic acid-3-ethylidene-2-[(6-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy]-3,4-dihydro-5-(methoxycarbonyl)methyl ester, commonly called excelside A, an isolated compound (2S,3E,4S) 2H-Pyran-4-acetic acid-3-ethylidene-2-[(6-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy]-3,4-dihydro-5-(methoxycarbonyl) 2-(4-hydroxyphenyl)ethyl ester, commonly called excelside B, and the compounds GI5, GI3, nuzhenide, and oleoside dimethyl ester.

The application of the active ingredient gentiopicroside in the preparation of drugs for inhibiting hepatitis B virus. The active ingredient gentiopicroside is a compound extracted and separated from the commonly used traditional Chinese medicine Gentiana quinquefolium in my country. The active ingredient gentiopicroside is mixed with pharmaceutically acceptable carriers in preparations such as those suitable for enteral and parenteral administration. Organic or inorganic solid or liquid excipients are mixed, and the pharmaceutical preparation can be in solid form such as tablet, capsule, powder, pill, granule, or in liquid form such as injection, emulsion, etc. Gentiopicroside was prepared into injections, and the drug efficacy test showed that ducks infected with duck hepatitis B virus were treated with intramuscular injection of gentiopicroside on the 7th day after infection. The inhibitory effect of duck serum DHBV-DNA level is remarkable, and the statistical processing results have very significant and significant differences, inhibitory effect (P<0.01-0.05), and the inhibitory effect of three batches of experiments can be repeated.
