Unformatted text preview: nly an organic extract showed antiproliferative effects against A549, C33A and MCF-7 cancer cells, giving IC50 equal to 17.0, 6.0 and 23.0 µg/mL respectively. In conclusion, findings of this study revealed that S. hermanii as a promising source of natural antioxidants and anticancer products. 1 POSTER PRESENTATION (NATURAL PRODUCT) NAT-P1 CHEMICAL CONSTITUENTS OF THE LEAF OF ALPINIA MUTICA 1 Nor Akmalazura Jani and Hasnah Mohd. Sirat 2 1 Faculty of Applied Science, Universiti Teknologi MARA Negeri Sembilan, Kampus Kuala Pilah, Beting, 72000 Kuala Pilah, Negeri Sembilan, Malaysia 2 Department of Chemistry, Faculty of Science, Universiti Teknologi Malaysia, 81310 Skudai, Johor, Malaysia E-mail: norakmalazura@ns.uitm.edu.my Alpinia mutica is a perennial herb belonging to the Zingiberaceae family. The n-hexane extract of the dried leaf of this species yielded three compounds, consists of two phenolics and one amide. Their structures were elucidated spectroscopically as 5,6-dehydrokawain, aniba dimer A and auranamide. The essential oil obtained by hydrodistillation from the fresh leaf was an alyzed by capillary GC and GC/MS. This leaf gave 0.005 % oil with β-sesquiphellandrene (13.2 %), β-bisabolene (9.0 %) and δ-cadinene (7.4 %) as the main components. 170 3rd ICYC 2010 Universiti Sains Malaysia NAT-P2 23rd-25th June 2010 SECONDARY METABOLITIES AND BIOACTIVITY STUDIES OF (Garcinia griffithii) 1 Tara Kamal, Muhhamed Nor, Deny Susanti and Muhhamed Taher 2 3 4 Department of Biotechnology, Faculty of Science, International Islamic University Malaysia, Jalan Istana, 25200 Kuantan, Pahang, Malaysia 2 Depatement of Biotechnology, Faculty of Science, International Islamic University Malaysia, Jalan Istana, 25200 Kuantan ,Pahang, Malaysia 3 Department of Biomedical, Faculty of Science, International Islamic University Malaysia, Jalan Istana, 25200 Kuantan,Pahang, Malaysia 4 Department ,of Pharmacetical Technology, Faculty of Pharmacy, International Islamic University Malaysia, Jalan Istana,25200 Kuantan, Pahang, Malaysia E-mail: tarakamal111@hotmail.com Nowadays, researchers are focussing their attention towards folk medicine for developing better drugs against microbial infections.
