[ Method] L. clethroides was extracted by three methods, including water extraction, water extraction-alcohol precipitation and 75% ethanol extraction, to determine the effec- tive components of extracts, and contents of calcium, phosphorus and Vc were calculated. [ Result] L. clezhreides contained calcium salt, chlorine, VB1, VB2, Vc and phosphate, but did not contain citrate, sulfate, carbonate or bicarbonate, acetate, lactate, VA , VD and Vs ; the contents of calcium and phosphorus in water extract were 150 and 3.34 mg/g, respectively, greatly exceeding their contents in water extraction-alcohol precipitation and ethanol extraction, while the difference in Vc content was not significant. [ CondusionJ The paper provides a reference for practical application of L. clethroides as an additive.展开更多
