Abstract
The invention discloses an extractive of camellia oleifera flowers and an application of the extractive in preparation of health-care drink. The extractive of the camellia oleifera flowers is prepared by extracting smashed raw material fresh camellia oleifera flowers or dried camellia oleifera flowers by extraction solvent water. A health-care drink prepared from the extractive of the camellia oleifera flowers has the wonderful color, aroma and taste, contains rich polysaccharide, polyphenol, flavone and procyanidine, and has good antioxidant activity, and by using the extractive, the removal rate of O2<-1>., OH. and DPPH. can be over 80%.
