ABSTRACT

Indonesia has numerous indigenous vegetables that potential as medicinal plants. Unfortunately, those have not been optimally utilized since lack of explorations of their nutritional   compounds   and   functional  properties that can provide beneficial for  human health. Concerning  the circumstances, Southeast Asian Food & Agricultural Science & Technology (SEAFAST) Center, IPB, has preliminary initiative to study in depth the nutritional   aspects   and   functional properties of several medicinal plants as models namely waterleaf (Talinum trianqulare Jacq Wild) and turkey berry (Solanum torvum Swartz). The aim  of this research is to investigate waterleaf (Talinum trianqulare Jacq Wild)  as a  source of soluble dietary fiber and turkey berry (Solanum torvum Swartz) as an antimicrobial compound. The research is carried out in order to  strengthen the indigenous potency of medicinal plants in Indonesia towards positive health benefits when ingested.

The  research  on  waterleaf (Talinum trianqulare Jacq  Wild)  consists  of three main work  stages,   i.e.   (1)  organic  and  inorganic  cultivation  of  waterleaf (Talinum trianqulare  Jacq  Wild)  plants;  (2)  sample  preparations  of  wet  and  dry sample methods;  and  (3)  physicochemical  analysis  that  covers  moisture  content, total dietary fiber, soluble and insoluble fiber, pectic substances and profile of oligosaccharides. Meanwhile,  the  work  stages  on  turkey  berry  (Solanum  torvum Swartz) research consists of (1) organic and inorganic cultivation of turkey berry (Solanum  torvum Swartz); (2)  sample  preparation  and  extractions  using  organic solvent; (3) qualitative and quantitative  analysis of bioactive  compounds of various turkey berry (Solanum torvum Swartz) extracts, and (4) antimicrobial activity test of turkey berry (Solanum torvum Swartz) extracts against some pathogens using well diffusion  method. Moreover, the metabolomics analysis of turkey berry (Solanum torvum Swartz) is also done. The research on both vegetables is still ongoing and is expected to be accomplished in 2 years.
