D,L-赖氨匹林干粉与注射用水配套,可用作止痛、消炎和抗凝血药。本品主要作用物是乙酰水杨酸,所以分析方法的基础在于它的分光光度法。乙酰水杨酸难溶于水,易溶于乙醇。而D,L-赖氨匹林与其相反。显然,含水有机溶剂是这两种物质的共同溶剂。乙酰水杨酸、水杨酸和D,L-赖氨匹林在加有4％(体积)二乙醚缓冲液溶液中的紫外光谱与在4％(体积)乙醇缓冲液中的光谱无异。由图可见(略),乙酰水杨酸和D,L-赖氨匹林的吸收光谱相重合,而水杨酸溶液在波长
D, L-lysiprownine powder and water for injection, can be used as analgesics, anti-inflammatory and anticoagulant drugs. The main role of this product is acetylsalicylic acid, so the basis of the analytical method is its spectrophotometry. Acetylsalicylic acid insoluble in water, soluble in ethanol. And D, L-lysiparoline and the opposite. Obviously, aqueous organic solvents are common solvents for both substances. The UV spectra of acetylsalicylic acid, salicylic acid and D, L-lysipacrine in a 4% by volume diethyl ether buffer solution were the same as those in 4% by volume ethanol buffer. As can be seen from the figure (omitted), the absorption spectrum of acetylsalicylic acid and D, L-lysipatrine coincide, and the salicylic acid solution shows an absorption spectrum at the wavelength
