collection of the same plant from Templer Park, a new
alkalo id (desmethoxyzanthophyll i ne) and f 1 i nders i ne
have also been isolated. A similar study on the bark
of another species, G. rupestris, collected from
Langkawi Island afforded
m e t h o xyg lyc o m a u r i n) ,
a new alkaloid (7-
g l yc o m a u r i n , d e s-N-
methylacronycine and stigmast-7-enol, while the leaves
of the plant gave an unidentified compound.
The antifungal activities of these plant extracts
were evaluated using the poison food and spore
germination techniques. The plant extracts exhibited
varying degree of fungitoxic response on the growth of
the fungal pathogens of chilli (Capsicum annuum L.).
The chloroform extract of G. calcicola collected from
Templer Park has been shown to be most effective in
inhibiting the mycelial growth, sporulation and spore
germination of Chaonephora cucurbi tarium,
Col1etotrichum capsici and C. gloeosporioides.
The antifungal compounds in this extract were
identified using TLC bioassay technique against
Aspergillus flavus. The results indicated that the
activity of the extract is due to the presence of its
major components: f lin d e r s i n e a n d
desmethoxyzanthophylline.

di Templer Park, satu alkaloid baru
(desmetoksizantofilina) dan flindersina telah berjaya
dipencilkan . Kajian yang serupa ke atas kulit batang
spesis yang lain, G. rupestris, yang dikumpulkan dari
Pulau Langkawi telah member ikan satu alkaloid baru ( 7 -
metoksiglikomaurin), glikomaurin, des-N
metilakronisin dan stigmast- 7-enol, manakala daunnya
pula member ikan satu sebatian yang belum dikenal
pasti .
Akti vi ti antikulat ekstrak tumbuhan tersebut
telah dikaji dengan menggunakan teknik 'poison food'
dan pereambahan spora. Ekstrak tumbuhan yang dikaji
menunjukkan aktiviti antikulat yang berbeza terhadap
pertumbuhan kulat patogen eili (Capsicum annuum L.).
Ekstrak klorofom G. calcicola yang dikumpulkan dari
Templer Park didapati paling berkesan mereneat
pertumbuhan misellum, pensporalan dan percambahan
spora Chaon ephora cucurbitarium, Colletotrichum
capsici dan C. gloeosporioides.
Sebatian antikulat dalam ekstrak ini telah dapat
dikenal pasti dengan menggunakan kaedah biocerakinan
TLC terhadap Aspergi 11 us f 1avus. Keputusannya
menunjukkan bahawa aktiviti ekstrak tersebut adalah
disebabkan oleh kehadiran komponen utamanya:
flindersina dan desmetoksizantofilina.
