Specialized Metabolites

Ahmad Faizal is interested in the field of plant secondary metabolite and metabolic engineering. He developes strategies to modulate a triterpene saponin (a class of secondary metabolite) production from medicinal plants. These are including the classic tissue culture techniques, polyploidization, genetic engineering of uncommon plant species using Agrobacterium-mediated transformation, flow cytometry, and metabolic engineering.

Production of starch and protein from duckweed

These plants are very simple, lacking an obvious stem or leaves. The greater part of each plant is a small organized “thallus” or “frond” structure only a few cells thick, often with air pockets that allow it to float on or just under the water surface. Depending on the species, each plant may have no root or may have one or more simple rootlets. In this project, biomass, starch and protein content of local duckweed isolates were investigated.

Medicinal Mosses and Ferns

It is estimated that more than about 25% of modern drugs used today are derived from plants. As a part of drug discovery, we develop tool to screen and select plant that possess interesting bioactivities. Among the medicinal plants, mosses (bryophytes) and small ferns are of our interest since these groups have not been given enough attention due lack chemistry information and the quantity for analysis. Previous study reported that both moss and ferns are rich in terpenoids compounds, phenols glycosides, fatty acids, including some rare aromatic compounds.

Elucidation of saponin biosynthesis in Javanese ginseng

For centuries, people have used a plethora of plants or plant-derived products with varying success to treat and cure diseases and injuries. However, only a small fraction of the immense diversity of plant metabolites has been explored for the production of new medicines and other products important to human well-being. The continuous need for new compounds with important medicinal activities has lead to the identification and characterization of various plant-derived natural products. As a part of this program, we study the production of potential pharmaceutical compound, mainly saponin from Talinum paniculatum or widely known as Javanese ginseng.

Formation of artificial agarwood

Naturally synthesized agarwood requires a lengthy process of up to thirty years, which impede its continuous production. Therefore, recent effort has been allocated to the elucidation of agarwood formation to stimulate its process rapidly. In this study, we artificially induced agarwood formation by injection and inoculation of cultivated Aquilaria malaccensis with strains of Fusarium solani isolated from different places in Indonesia.

Rinda KiranaInteraction between Bactrocera-chili peppers

Fruit fly is one of the major pests of commercial fruits in Indonesia. Potentially, this pest causes estimated losses up to 100%. Despite many reports describing fruit fly species, only few studies has been done to elucidate their association with chili peppers.
