The leaf and bark extracts of Salix subserrata showed
promising antibacterial, antifungal, and antialgal activities. The bio-guided study of the
chemical constituents of the bark and leaves of Salix subserrata (Salicaceae) has resulted in the
isolation and characterization of eight compounds. These six compounds were identified as (+)
catechin (1), 1,2-benzenedicarboxylic acid, bis (2-ethylhexyl) ester (2), saligenin (3), methyl
1-hydroxy-6-oxocyclohex-2-enecarboxylate (4), catechol (5), propyl acetate (6), beta-sitosterol
(7), and beta-sitosterol glucopyranoside (8), were isolated for the first time from Salix
subserrata. The above compounds were individually identified by spectroscopic analyses and
comparisons with reported data. Preliminary studies indicated that compound 1, mixture of
compounds 3/4, and 7 showed good antibacterial, fungicidal, and algicidal properties.
