Effect of drying methods on functional compounds in methanol extracts of Centella asiatica
Abstract
Centella asiatica is a pre-historically utilized medicinal herb well recognized as a traditional phytotherapeutic substance for treating various diseases. Centella asiatica possesses pharmacological value due to the presence of phytochemicals like flavonoids and terpenoids, mainly asiatic acid, asiaticoside, and madecassoside. Its role as a functional component in developing various processed food products and packaging films is continuously being explored. The present study is focused on the effect of drying methods (shade drying, cabinet drying and hot air oven drying) on functional compounds in methanol extracts of Centella asiatica. The Centella asiatica leaves were dried through shade drying (28ºC), hot air oven and cabinet drier at three different temperatures (40ºC, 50ºC, and 60ºC). The methanol was used for the extraction of the bioactive compounds. The total yield and functional compound were identified viz., FTIR in all the dried powders and methanol extracts of Centella asiatica respectively. The result of extracts revealed that shade dried obtained a maximum yield than the cabinet and hot air oven-drying methods. The FTIR study reveals the presence of alkanes, amines, aldehydes, carboxylic acids, aromatic compounds, nitro compounds, esters, and alkyl halides, in all the methanol extracts of Centella asiatica. Centella asiatica is a medicinal herb that has been used for centuries to treat a variety of health conditions. It is known for its wound healing, anti-inflammatory, and antioxidant properties. The identified compounds may be responsible for health, including wound healing, skin health, and cognitive function.
