The Study of the Use of Some Morus alba Linn. Extract Against Fungi Isolated From Durian Leaves.

Abstract

This research was conducted to investigate the efficiency of crude extracts from different parts of mulberry that can inhibit the growth of the fungi extracted from durian leaves. Two species of fungi extracted from durian leaves were selected, namely, Phyllosticta sp. and Colletotrichum sp. Leaves, fruits, roots and stems of mulberry were extracted by 95% ethanol and hexane. The average dry weight of the extract with 95% ethanol were 17.45, 21.53, 5.52 and 5.51 g, respectively, while the average dried weight from hexane-extracted solutions were of 18.35, 29.29, 4.67 and 4.67 g, respectively. The effectiveness of the extracts were determined by using Paper Disc Diffusion at 300, 600 and 900 milligrams per milliliter.  It was found that the extracts from Mulberry fruit, root, and stem by 95% ethanol could inhibit Phyllosticta sp. at the concentration of 600 mg/ml. The diameter of clear bands were 1.29 ± 1.13, 1.86 ± 0.49 and 2.87 ± 0.29 mm. respectively with the best inhibition percentage of 35.07 - 82.09. Mulberry root and stem extracted with 95 percent ethanol were tested on Colletotrichum sp. at a concentration of 600 mg per milliliter, the diameter of the clear band was 2.37 ± 0.73 and 1.86 ± 1.03 mm, respectively. The highest percentage of inhibition was 10.10 - 24.24. The extracts from mulberry leaves did not inhibit the fungus. The solutions extracted with hexane solvent did not inhibit both fungi.
