IIT Guwahati researchers have developed a low-cost membrane technology to produce psychoactive drugs and anti-aging compounds from wide range of agricultural resources like camellia sinensis, citrus fruits and peels especially orange peels, berries, ginkgo biloba, parsley, pulses, tea, sea buckthorn and onions. The technology was patented and developed by Prof Mihir Kumar Purkait, Head, Centre for the Environment, and Professor, Department of Chemical Engineering along with his MTech student V.L. Dhadge. This process doesn’t require any organic solvents as used commercially in the industry and so, can cut down the production cost and price drastically. Because of medicinal applications, anti-aging compounds have gained popularity as ingredients in pharmaceutical industry. These are also found in smaller amount in bamboo leaves, grapes, apples, and other natural sources.
