Abstract:
Green peel of Juglans mandshurica was used as raw material，the optimal extraction method of the total alkaloid，and its antioxidant and antibacterial properties was studied by ultrasonic assisted and ultraviolet spectrophotometry in order to supply reference for using alkaloids of green peel of Juglans mandshurica.The results showed that the optimum extraction conditions generated by orthogonal tests were as follows,volume fraction of ethanol of 80%，solid-liquid ratio of 1∶10 g?mL-1，ultrasonic temperature of 40 ℃，and ultrasonic time of 40 minutes.In addition，the antioxidant tests showed that the total alkaloids of green peel of Juglans mandshurica had scavenging effect on hydroxyl radicals，nitrite ions and superoxide anion.The IC50 values calculated by linear-regression analysis were 0.030 g?L-1(?OH)，0.029 g?L-1(NO2-)，and 0.033 g?L-1(O?[TX-*4]2).The results of antibacterial tests showed that total alkaloids could control the growth of wood-rotting fungi of both Gloeophyllum trabeum and Coriolus versicolor.
