Abstract:
AIM To investigate the effects of drying temperature,growing area and plucking time on hederacoside C,α-hederin from leaves of Hedera helix L..METHODS Three batches of H.helix leaves plucked in different time from two growing areas were dried in a vacuum oven to the constant weight at 60 ℃,70 ℃,80 ℃,90 ℃ and 105 ℃,respectively.Two saponins in the processed leaves were determined by HPLC.The powders of the processed H.helix leaves of different batches were mixed with proper ratios,which were determined by least squares optimization method with constraints.RESULTS The content of hederacoside C in the processed H.helix leaves of the three batches increased while that of α-hederin decreased with increasing temperature.The relative error between measured value and desired contents of hederacoside C and α-hederin in the mixed H.helix leaves was less than 5.5％.CONCLUSION The effects of three factors on the content of two saponins in the H.helix leaves are in the order of drying temperature,growing area and plucking time.Mixing processed H.helix leaves of different quality statues reasonably can control the contents of two saponins in a certain range.
