ABSTRACT
The effect
of season on yield and quality of organic solvent extracts from Gracilaria changii was determined. The
sustainability of the bioactive compound of G. changii from Malaysia was investigated by using the TLC and FTIR standards
methods. Studies was carried out to examine the sustainability of the bioactive
compound in the various extract obtained from G. changii collected from Pantai Morib, Beach Selangor
Malaysia on bimonthly for a period of one year in 2003. This study revealed
that the bioactive compounds was present all over the
year but with different quantities. In general the variation in yield or
quantities of bioactive compound was related to environment. G. changii can be considered a candidate for drug development
since it retained the number of bioactive compound.
Keywords: Gracilaria changii; effects of season
ABSTRAK
Dalam kajian ini kesan musim terhadap hasil dan kualiti ekstrak daripada Gracilaria changii dengan menggunakan larutan organik telah dikaji. Kelestarian bahan bioaktif G. changii dari Malaysia telah dikaji dengan menggunakan kaedah piawai TLC dan FTIR. Kajian telah dijalankan untuk menilai kelestarian bahan bioaktif dalam pelbagai penyediaan ekstrak daripada G. changii yang disampelkan dari Pantai Morib, Selangor, Malaysia setiap dua bulan selama satu tahun pada 2003. Keputusan kajian menunjukkan bahawa komponen bahan bioaktif hadir sepanjang tahun tetapi dengan kuantiti yang berlainan. Pada umumnya didapati variasi dalam hasil atau kuantiti komponen bahan bioaktif berkaitan dengan keadaan persekitaran. G. changii mungkin boleh dijadikan calon untuk pembangunan dadah semula jadi kerana ia mengekalkan bilangan komponen bahan bioaktifnya.
Kata kunci: Gracilaria changii; kesan musim
