| 520 | |a Syzygium is regularly misidentified in ecological inventories which caused serious problems for biodiversity management. Although Syzygium polyanthum is one of the favourite Ulam consumed for ages in Peninsular Malaysia, but its written traditional knowledge is lacking. However, the species is substituted with other species due to their extreme similarity in morphology, aroma and flavor. The medicinal property of serai kayu hutan was highlighted by the local traditional healers but not yet ascertained scientifically. The aim of this study is to document traditional medicinal knowledge, morpho-anatomical features, biological activity and chemical composition of S. polyanthum (serai kayu and serai kayu hutan). Ethnobotany was carried out through oral interviews. Light and scanning electron microscopes were used to determine anatomical features. Phenetic analysis using parsimony (P AUP). FTIR coupled with chemometrics was employed to discriminate the cultivars. DPPH radical scavenging activities, 0.glucosidase, ferric reducing antioxidant power (FRAP), antimicrobial activities using disk, agar well methods and lethal dosage were determined. Essential oil composition was determined using gas chromatography mass spectrometry. Mineral elemental analysis through inductively coupled plasma-mass spectrometry and neutron activation analysis. Ethnobotany documented fourty six medicinal plants; serai kayu hutan reportedly used by Malays in treating endometriosis, HIV and diabetes while serai kayu has the highest used value, relative frequency citation and fidelity level % at 0.068, 0.872 and 100 respectively. Highest jaccard index (JI) was 17.4. Morphology revealed less variation between the cultivars. However, they varied anatomically in terms of stomata, presenceof druses, oil secretion gland, and vascular tissue shapes. Dendrogram revealed variation among cultivars. Chemometrics showed relationships existed. High DPPH, a-glucosidase and FRAP with ICso of 2.34, 19.66 ug/ml. and 36.94 mmollg were found in serai kayu hutan leaves respectively. Moderate zone of inhibition was recorded (4-28mm) similar to the ampicillin used excepts in Listeria monocytogen no inhibition. No mortality at 2000 mg/kg. Oil analysis revealed 40 and 29 compounds amounting to 70.29 and 90.9.3 % in serai kayu and serai kayu hutan respectively. Essential oil distinct difference is the presence of methyl citronellate in serai kayu hutan. Cu, Ni, Zn, K, Na, Fe, Cr, and V were found in the leaves, bark and root of both cultivars; and are known to be very important in maintaining the good health of human. Ethnobotany reported serai kayu hutan for the first time ever. Diagnostic characters from morpho anatomy, chemometric and chemical composition would serve as markers for identification of the species. Cultivars were found to be vulnerable species; therefore, proven documented biological activity and explored essential oil of the cultivars should be utilised for product development to avoid future over-sampling and extinction. The study recommended immediate conservation of the cultivars. | ||
