Abstract

A research on effectiveness of extracts of teak (Tectona grandis L. f) leaves in inhibit the
growth of a species of fungi, Hormiscium sp. has been carried out.  The leaves used in this
research were young leaves (number 1 and 2), and old ones (number 5 and 6), with four
concentrations: 0, 2, 5, and 10 %.  The media utilised were bean sprouts agar, and the
replications was 3 times.  Qualitative tests were undertaken for the flavonoids, while alkaloid
tests were based on Culvenor Fitzgerald methods.  Qualitative tests of triterpenoids and
steroids were undertaken by utilising Lieberman – Burchard reagents (L-B reagents).
Parameters observed were colony diameters, micellium weights (dry mass), and numbers of
conidia (ml
).  Results of this research showed that extracts of teak (T. grandis) leaves were
able to inhibit the growth of Hormiscium sp.  The capability of inhibitions was increased as
the extract concentrations increased (for both, that of the young and old leaves), even
though extracts of the young provided a higher capability of inhibitions compared to the
old ones.
