The present invention relates to a strong base-initiated N-carboxyanhydride rapid ring-opening polymerisation method. Specifically, the method comprises steps of: performing a polymerisation reaction with one or more amino acid N-carboxyanhydride monomers in an organic solvent in the presence of an initiator, so as to form an amino acid polymer, wherein the initiator is selected from the following group: LiHMDS, NaHMDS, KHMDS, or a combination thereof. The method significantly increases the speed of traditional NCA polymerisation and prepares a long-chain polymer, and the prepared amino acid polymer may be used as an anti-bacterial material, an anti-tumour material, a tissue engineering scaffold or a self-assembling material.

Preparation and application of line leafflower lactone A for treating myocarditis having a structure of The compound shows positive therapeutic activity against Coxsackie virus and significant dose dependent correlation. The line leafflower lactone A prevents disease in mouse models of experimental autoimmune myocarditis and onset of the process by intraperitoneal injection of a dose of 20 mg/kg/d. When increased to 100 mg/kg/d, the line leafflower lactone A shows positive therapeutic effect on EAM. Line leafflower lactone A is used as the sole active ingredient and combined with a conventional pharmaceutical carrier in a drug for treating myocarditis, and the pharmaceutical composition may be in the form of tablets, dispersible tablets, mouth collapse tablets, retard tablets, capsule, soft capsule, dropping pill, granules, injection, powder injection, or aerosol.

A method for preparing dehydrocavidine, dehydroapocavidine and their respective composition is provided. The composition is first prepared by isolating and purifying the quaternary ammonium alkaloid components from the medicinal plant 'Yan Huang Lian' (Bunting) through the processes of solvent extraction, water-phase organic extraction, crystallization and recrystallization, and then drying to obtain said composition containing dehydrocavidine and dehydroapocavine. When necessary, the composition or their crude extracts can be separated by chromatography to obtain dehydrocavidine or dehydroapocavidine. Dehydrocavidine, dehydroapocavidine or their respective composition can be used in manufacturing medicines for treating viral hepatitis, hepatic injury, influenza, AIDS, tumors or arrhythmia.
