Abstract

Polysaccharides from Glechoma longituba were extracted in the present study,and four factors including p H,liquid-solid ratio,extraction temperature and time were optimized by univariate tests and response surface methodology. The results showed that the highest yield of polysaccharides extracted from Glechoma longituba reached 3.40% ±0.05% when the process was p H7.2,liquid-solid ratio 33 ∶1(m L/g),temperature 89℃ and extraction time 160 min. This research might provide a theoretical basis for the further development and utilization.
