ABSTRACT
OBJECTIVE:
To establish quality standard for Zhuang medicine Homalocladium platycladum.METHODS:
TLC method was used for qualitative identification. HPLC method was used to determine the content of quercetrin in samplesAgilent Zorbax SB-C18 column,mobile phase consisted of acetonitrile-0.1% acetic acid(2080,V/V),flow rate of 1.0 mL/min,detection wavelength of 360 nm,column temperature of 30 ℃,injection volume of 10 μL. The contents of moisture,total ash and extract in samples were determined. referring to Chinese Pharmacopiea(2015 edition).RESULTS:
TLC spots of H. platycladum were clear and well-separated without interference from negative control. The linear range of quercetin were 0.023-0.46 mg/mL(r=0.9991). RSDs of precision,stability and repeatability tests were all lower than 2.0%. The average recoveries were 98.01%-103.05%(RSD=1.71%,n=6). The contents of moisture,total ash,extract and quercetrin in samples were 6.39%-9.78%,2.82%-8.07%, 0.02%-0.27%,14.14%-28.45%,0.09%-0.50% respectively.CONCLUSIONS:
Established trial can be used for quality control of Zhuang medicine H. platycladum.
