HPLC law determines content of medicine of calcic raw material of rice Glenn Nai and concerned material HPLC Determination Of The Concentrations Of Mitiglinide And Its Related Substances
Purpose: 肏 PLC law determines the content of medicine of calcic raw material of rice Glenn Nai reachs his to concern material, the content of medicine of calcic raw material of Nai of the Glenn that it is rice determines with concerned material offer detect method, make control a standard character. Method: Meng sends of Chinese torreya of hazel a kind of apple blind a surname why raiseds paths between fields Mei? with phosphoric acid of 0.1 mol · L-1 salt of amortize of 2 hydrogen ammonium (methanol of PH=3.0)- of phosphoric acid adjustment - second nitrile (25:35:40) detects as; of photograph of going from place to place wavelengh is 210 nm; column lukewarm velocity of flow of 30 ℃ ; is 1.0mL · Min-1 about. Result: Honest of be angry of arsine of tan Yi farring away the chroma that plum of history Qian shrimp casts? MiG lists Nai calcium is in sexual relationship of planted agent of limits of ML-1 of · of 14-350/ μ G is good, correlation coefficient is 0.9993. Conclusion: Plum Ji scrupulously and respectfully ⒆ already? of courtyard of sell of two ⒆ ㄊ can use Yumigelienai the content of medicine of calcic raw material reachs concerned material determine.
