摘      要：Currently,there is a strong focus on industrial production of chlorophyll as a natural *** factors are required in the economically feasible process to make chlorophyll production:material with high pigment content and efficient extraction *** this work,extraction of chlorophyll from harvested black locust(Robinia pseudoacacia)leaves,Scots pine(Pinus sylvestris)needles,field sow thistle(Sonchus arvensis)leaves,and green microalga(Chlorella sp.)was *** highest pigment content was detected in Chlorella cells(4.46%)followed by black locust leaves(1.63%),sow thistle leaves(1.48%)and pine needles(0.38%).The chlorophyll extraction rate was the highest for black locust leaves(k=3.59 h^(-1)),sow thistle leaves(k=2.90 h^(-1))and Chlorella cells(k=2.80 h^(-1))with the use of methanol as a *** investigated materials,needles showed higher resistance for chlorophyll extraction(k=0.93 h^(-1))when compared to leaves and *** of extraction kinetic constant were much lower for all materials(0.22-1.12 h^(-1))in the case of using ethanol as a *** locust leaves and Chlorella cells were proved to be the most attractive materials for chlorophyll production.
