主　　题：Phenolics Flavonoids Kaempferia parviflora Extraction 

摘      要：Kaempferia parviflora plants derived from in vitro culture were grown in the glasshouse. A comparison of the yield of total phenolics and total flavonoids under varying extraction conditions from rhizomes harvested from plants of different ages was undertaken. The results showed that phenolic and flavonoid contents in the rhizomes were highest 8 months after planting. Another study found that 2 g rhizomes extracted in 50 ml of water at 90°C for 120 minutes gave the best yield of phenolics and flavonoids. Under these conditions, an average of 210 mg GAE/g dry weight of total phenolics and 81 μg QCE/g dry weight of total flavonoids were obtained.
