Objective: To study the influence of growth years and environment factors on the quality of Alpiniae Officinarum Rhizoma.The galangin content of 53 representative samples from Guangdon province and Hainan province was determined by HPLC. Method: With the method of HPLC
ODS-C18 column (4.6 mm×250 mm
5 μm) was used
the mobile phase was as methanol-0.2% phosphorice acid(55:45)
the detection wavelength was at 266 nm
the flow rate was at 1 mL·min-1
the column temperature was at 30℃. Result: The average galangin content of samples from Hainan province was obviously higher than that from Guangdong province. And the galangin content of 4-year-old samples was highest among the samples planted 2 to 5 years old. What is more
the galangin content of 4-year-old smaples harvested in the early spring was clearly higher than that harvested in the late summer and early fall. Conclusion: The quality of cultivated samples from Hainan province was higher than that from Guangdong province.The best harvest period of Alpiniae Officinarum Rhizoma was in the fourth year of late summer and early fall.
