چکیده
|
Based on a previous test (fractionation) on nephrolepis biserrata, lignocellulose contains 34.27% of pectin and oligosacharides, 1.78% of hemicellulose, 20.66% of cellulose and 43.29% of lignin. the optimum time for extraction of pectin from nephrolepis biserrata leaves was investigated. extraction time of 60, 90, 120 minutes at ph 1.5 and temperature of 80°c were found to significantly affect the extraction of pectin from nephrolepis biserrata leaves. maximum pectin yield is 15.8%, which was obtained in sulphuric acid solution of ph 1.5 at 80°c for 120 minutes.
