Connecting Science and Technology for a brighter tomorrow

The major emphasis of Natural Products Chemistry Group, since its inception, has been on chemical investigation of selected traditionally reputed medicinal plants of the northeastern region of India for drugs, pest management agents and nutraceuticals. This department during last three decades of its existence has investigated a large number of plants and isolated a quite a few interesting molecules of different class having novel structures and published ~ 400 research papers in peer reviewed national and international journals. The department has filed a sizeable number of patents and developed several technologies and transferred to private industries, as well. The technology for chirally pure arteether has recognition from Third World Network of Scientific Organization (TWNSO), TWAS, Italy. The technology for Arteether, Artemether and Artesunate has been transferred to M/s FDC Ltd. Munbai for commercial exploitation. In the recent past, this department played a key role in developing two herbal drugs: one for treatment of rheumatoid arthritis and one for fungal infection in collaboration with Medicinal Aromatic and Economic Plants Group, Clinical Centre and Prof. Samir Bhattacharya’s group in Visva Bharati Santiniketan. Natural Products Chemistry Group also participated in important CSIR projects as well as several network projects since its inception; thereby the scientists of this department acquired unique expertise in this area. The scientists of this department bagged several awards and recognitions and also became known nationally and internationally. This department has established collaboration with few premier institutes within and outside the institute in selected areas to address the issue meaningfully, as well. The Group has gained expertise in the following aspects of Natural Products Chemistry:
  • Value addition to natural products through chemical/ microbiological routes.
  • Stereo selective total synthesis of biologically active natural products.
  • Technology development for drugs/drug intermediates.
  • Nutraceuticals & Functional food
  • Plant based pest control agents
  • Phytochemical analysis service to entrepreneurs and medicinal plant farmers
  • Herbal drug development
