Larvae cause enormous damage to brinjal pods and shoots and the population management is normally done with frequent application of insecticides.Item Lipase inhibition effects of four pure compounds isolated from an endolichenic fungus Xylaria psidii(Institute of Chemistry Ceylon, 2018-05) Sinthujah,S; Maduranga, H A K; Attanayake,R.N; Weerakoon,G; Paranagama,P.AObesity caused by long-term energy imbalance is an epidemic disease in developed and developing countries. T he prevalence of obesity is increasing at an alarming rate, but, unfortunately, only a few medications are currently on the market.Item Molecular identification and screening of anti-obesity activity and antidiabetes property of selected endolichenic fungi in mangrove ecosystem of Puttalam lagoon(Institute of Chemistry Ceylon, 2018-05) Maduranga,H .A. K; Attanayake,R .N; Weerakoon,G; Paranagama,P.ANatural products based drug development has become an attractive area of research since there are limited options available to treat certain non-infectious diseases such as diabetes and obesity. Among these natural products, it has been reported that secondary metabolites of fungi, especially of endolichenic fungi (ELF) have the ability to produce promising bioactive compounds.
