Introduction Gambang lant secondary metabolites present chemicals and pharmaceutical Malaysia PP properties interesting for human health compounds belonging to the terpenoids, alkaloids and flavanoids are currently used as drug or as dietary supplements to cure or prevent various chronic and acute diseases (Raskin et al., 2002). Many thousands of wild have great economic and cultural importance, providing food, medicine, fuel, and clothing around the world. Plants also play a key role in maintaining the earth’s environmental balance and ecosystem stability. They also provide habitats for the world’s animal and insect life (Ahmed et al., 2001). Memecylon edule (Melastomateceae) are growing as small shrubs or trees in tropical and sub tropical regions in the various part of India, Malaysia (clausing G. et al., 2001). M.edule from india is mostly found in Karnataka, Andhra Pradesh and Tamil Nadu (Ranjit Daniels RJ et al., 2007). The plant is well known for its use as a mordant in silk dyeing in the Northeast of Thailand. Memecylon edule trees are not only beautiful but also

useful. It provides hard timber used for building house boat and walking s l a c

sticks. Phytochemical screened for alkaloids saponins, steroid components, i d o essential oils, glycosides and hydrogen cyanide in families i r

Discussion 23.275, squalene rt 24.253, Hexa tri contane rt 26.148, In earlier phytochemicals explore of whole Hexa decane rt 28.092 respectively. (Table 2). Memecylon edule genus evidenced the presence of 13 fattyacids, 12 methyl tetradeconate, glucose, aminoacids, carotenoids, glycosides and saponins (stephan L., 1981). The strongest antibacterial effect was found in chloroform extract of seed extract of Memecylon edule against Bacillus subtilis and the weekest activity against Vibrio chlorae. In case the anti bacterial studies have shown that the chloroform and ethyl acetate extract against werte less than ampicillin (Tamizhamudu elavazhagan et al.,2010).Memecylon malabaricum (Malestomataceae) shown antibacterial agent (Kiran kumar Hullatti et al., 2004).

5. Conclusion The present work was explored the bioactive Table - 2. GC-MS results obtained from Memecylon compounds in methanolic extract of Memecylon edule edule methanolic crude extract and antibacterial activity against harmful human pathogens. The crude extract os Memecylon edule GC- On the basis of the FT-IR Spectra analysis of Memecylon MS result was showed the presence of long chain fatty edule crude extract the maximum peak value 3413.51 acids, steroids and saponins. In that compounds are and minimum peak value is 761.49 cm-1. (Fig.2) the responsible for inhibit growth of disease causative agents. From the study conclude methanolic extract of Memecylon edule act as good antimicrobial agents and novel pharmacological product development plant resources.
