[Study on the use of ultrasound technique in extraction of polysaccharides from Loquat leaf].
In order to gain the optimal extract condition of extraction polysaccharides in Loquate leaf by ultrasound technique, the single factor and the orthogonal experiments were carried. The results showed that the optimal condition turned out to be ultrasound extraction time 35 min, ultrasound power 120W, extraction temperature 60 degrees C and the liquid-to-solid ratio 12: 1. In contrast to conventional extraction method, the ultrasound technique could be a better method for extracting the polysaccharides from Loquat leaf with a higher yield and shorter time.
