Objective To optimize the honey-steam processing technology of Ploygonatum odoratum.Methods The content and anti-oxidant activity of polysaccharides,saponins,flavonoids,ethanol extracts,water soluble substance,and water were taken into consideration.The effects of honey-moistening time,solid-liquid ratio,honey-steam time,and honey-steam temperature on each index were studied.The best extraction condition was optimized using the orthogonal test coupled with the multi-index comprehensive evaluation.Results Th...
