Abstract. In recent years, natural fibers have acquired a fundamental role in the industry because, besides being available in great abundance, they are bio-renewable. These are mainly composed of lignin, cellulose and hemicellulose, which are natural polymers that shape the cellular wall of plants. In Peru, there is a great variety of natural resources with great potential where fibers can be extracted from or used like such, one of them is the “Ichu”, a type of straw that grows abundantly in highland areas, it was used as food for camelids for many years and now, it is simply burned to recover areas. For industrial applications, especially for composite materials, it is important to know the mechanical resistance of these fibers, which is directly related to the cellulose content, because of this it is necessary to characterize them chemically. Therefore, an efficient methodology, based on technical standards TAPPI, has been applied and validated to determine the percentage content of lignin, cellulose and hemicellulose, as well as moisture, ash and extractives of the fibers in order to determine how their performance would be for different applications. For that purpose, the species Jarava ichu from Cusco (3400 masl) and Huancavelica (4100 masl) have been analyzed and compared. The results show that geographic and climatic variations influence the chemical composition, hence higher altitude means the plant had a higher percentage content of lignin and lower content of cellulose.
