Extraction and Identification of Biomolecules from Lignin Alkaline Hydrolysate from Coffee Husk


Lignin has aroused great interest in the scientific and economic areas because of its aromatic and complex nature. It can be used as a raw material for obtaining aromatic aldehydes but the great potential of lignin is not satisfactorily utilized. The interest is justified by the fact that, when its structure is spun off through pre-treatment processes, it produces some phenolic compounds of important industrial interest. These are bioactive compounds that can be used to promote benefits to human health, such as reducing the incidence of degenerative diseases like cancer and diabetes, as antioxidant, ant mutagenic activities, anti allergic, anti-inflammatory and antimicrobial effects. The present work aimed to the extraction and identification by UPLC-MS of biomolecules found in alkaline lignin hydrolysate from coffee husk. These compounds were classified as terpenes with relevant biological activities which make them interesting for pharmaceutical and cosmetic industries as discussed in literature.
