A process for the extraction of Vitamin E from annatto plant matter is disclosed wherein annatto seed matter is subjected, before extraction, to acidification using amla fruit matter. After the acidification, the mixture of the two plant matters is extracted by water. The acidification converts the vitamin E compounds in the plant matter into more water-soluble forms, thus enhancing the vitamin yield. More of the vitamin is obtained in the ester form than in the form of vitamin alcohols. Processing time is reduced.
