Abstract:
OBJECTIVE: To optimize the preparation technology of phloroglucinol phospholipids complex and study its physicochemical properties.METHODS: The preparation technology for phloroglucinol phospholipids complex was optimized taking the molar ratio of phloroglucinol to phospholipids(A),reaction temperature(B) and reaction time(C) as factors and complex ratio of phloroglucinol and phospholipid as index.The dissolubility and oil/water partition coefficient of the complex in different solvents were determined and compared with crude drug,and the new complex's physicochemical properties were validated by UV and IR(infrared spectra).RESULTS: The optimized preparation conditions for phloroglucinol phospholipids complex were obtained as follows: A was 1∶2;B was 60 ℃ and C was 2 h.The complex ratio remained at above 98%.Compared with phloroglucinol crude drug,the phloroglucinol phospholipids complex in water or chloroform showed increase in both dissolubility and oil/water partition coefficient.UV and IR confirmed that no new complex had been formed from phloroglucinol and phospholipids.CONCLUSION: The optimized technology greatly enhanced the dissolubility and lipotropy of the phloroglucinol phospholipids complex.
