A novel anti-Tobacco mosaic virus(TMV) protein designated as gynostemmin was isolated from Gynostemma pentaphyllum. Its molecular mass was 27 kD and the N-terminal 19 amino acid residues were DINFSLAGADGQTYNTFIA(SWISS-PROT accession number P83206).

• 以半叶法测定抗烟草花叶病毒(Tobaccomosaicvirus,TMV)活性为监控手段,采用(NH4)2SO4分级沉淀、阳离子交换及亲和层析等方法,从绞股蓝(Gynostemmapentaphyllum)中分离到一种抗TMV蛋白,其分子量约为27kD,N端19个氨基酸残基为DINFSLAGADGQTYNTFIA(SWISS-PROT登录号为P83206)。
