Analysis of Yield of Eleutherosides B and E inAcanthopanax divaricatusandA. koreanumGrown with Varying Cultivation Methods

An analysis of the yield of eleutherosides B and E inAcanthopanax divaricatusandA. koreanumwas performed using high performance liquid chromatography to evaluate production by different cultivation methods. InA. divaricatusandA. koreanum, the total content of eleutherosides B and E was 2.466–7.360 mg/g varying by plant section, 3.886–11.506 mg/g by pinching site, 3.655–10.083 mg/g by planting time, and 3.652–10.108 mg/g by fertilizer ratio. Thus the total content of eleutherosides B and E inA. divaricatusandA. koreanumdiffered depending on cultivation methods. These results present useful information for high eleutheroside content applications inA. divaricatusandA. koreanum. This information can affect selection of plant section and cultivation methods for nutraceutical, pharmaceutical, and cosmeceutical material development.
