Determination of β-Carotene in Dried Grass

    Abstract

    AT the time when the tentative official method for the estimation of carotene in dried grass1 was drawn up, it was recognized that it gave results which included one or more pigments other than β-carotene2,3. However, at that time there seemed little chance of working out a satisfactory process for β-carotene on account of difficulties in obtaining a suitable adsorbent; and in accordance with the usual custom it was decided to return the whole of the petrol-soluble phase as 'carotene'. Although it has been shown that β-carotene predominates, yet this may account for only 70 per cent or even less of the 'crude carotene'.
