[Determination of paracetmol caffeine and ephedrine hydrochloride in likeshu capsules].
Paracetamol (P), caffeine (C) and ephedrine hydrochloride (EH) are there physiological active component in Likeshu capsules. We have proposed the determination method of these three components using extractive separation-spectrophotometry. Only one amount weighed of sample is required to determine them. The recoveries of P, C and EH were 97.51 +/- 0.64% (n = 9), 98.24 +/- 1.04% (n = 8) and 98.58 +/- 1.09% (n = 9) respectively. The results of determination of samples agreed with those of the HPLC method. This method is sensitive, accurate and simple. The other ingredients of Likeshu capsules do not interfere.
