RESUMEN
Objective:To compare the total daily doses of 16 active components in big honeyed pills, concentrated pills and tablets of Fuzi Lizhongwan. Method:Three dosage forms of Fuzi Lizhongwan were prepared according to the process described in the literature. RRLC-QqQ-MS was employed to analyze the contents of 16 active ingredients with mobile phase of 0.1%formic acid aqueous solution-0.1%formic acid acetonitrile solution for gradient elution,the separation was performed on a Accucore RP-MS column(2.1 mm×100 mm, 2.6 μm) with a flow rate of 0.3 mL·min-1 and the column temperature at 30℃, the mass spectrometry condition was electrospray ion source, positive and negative ion switching mode for detection, multi-reaction monitoring mode(MRM) for scanning. The contents of 16 active ingredients were calculated, and the normalization arithmetic method was used for comparing the total daily doses of these active ingredients in three dosage forms of Fuzi Lizhongwan. Result:Processed products of Aconiti Lateralis Radix Praeparata were used as raw powder in preparation process of the three dosage forms, so there was no significant difference in the contents of six alkaloids in the three dosage forms, while the contents of other 10 active ingredients from Zingiberis Rhizoma, Codonopsis Radix, Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle were significantly higher in big honeyed pills than those in concentrated pills or tablets(PConclusion:The total daily doses of 16 active ingredients in the three dosage forms of Fuzi Lizhongwan are significantly different caused by preparation process, prescription and dosage.
RESUMEN
Objective To comparative analyze the contents of 20 active ingredients in two dosage forms of Zhizhu Pills (ZP) and Zhizhu Granules (ZG). Methods Three batches of raw materials were used for the preparation of ZP and ZG according to the preparation process of China Pharmacopoeia (2015 Editon). Twenty active ingredients in the two dosage forms were detected simultaneously using high-performance liquid chromatography-triple quadrupole mass spectrometry (HPLC-QqQ-MS). The separation was performed on a Poroshell 120 SB-C18 (100 mm × 4.6 mm, 2.7 μm) column with a flow rate of 0.5 mL/min. Mobile phase consisted of 0.1% formic acid in water (A)-0.1% formic acid in acetonitrile (B). The column temperature was set at 30 ℃. The gradient elution conditions: 0-7 min, 23% B; 7-17 min, 23%-80% B; 17-20 min, 80%-100% B, 20-30 min, 100% B; flow rate was 0.5 mL/min. Results The contents of 20 active ingredients in the pills were 1.48-13.37 times that of the granules, the total difference of them perday were 493.02-615.08 mg. Conclusion There were significant differences in the content of active components in the two dosage forms of ZP and ZG, especially those components with poor solubility in water and thermal instability.
