The invention relates to a process for the isolation of components from plant material of Miscanthus. The process comprises three subsequent extractions. The first extraction yields an extract comprising one or more compounds selected from the group of antioxidants， polyphenols， proteins， sterols， acids， alcohols， ketones， aldehydes and aromatic compounds. Thereafter， the plant material is subjected to two extractions with a metal hydroxide (e.g. NaOH)， the first performed at a lower pH than the second. These steps yield a sugar fraction and a Iignin fraction， respectively. Finally， from the residue after the third extraction， cellulose is isolated.
