- Abstract
THE prominence now being given to rose hips as a source of vitamin C has tended to obscure their value as a source of other vitamins. Svensson1 reported in 1936 that different species of Scandinavian rose hips formed a rich source of vitamin A, since they contained carotene equivalent to 6,000 to 10,000 I.U. of vitamin A per 100 gm. We have found British hips also to be a rich source of vitamin A. Using dried extracts prepared in these laboratories from several tons of ripe hips, mainly R. canina and R. dumetorum, collected in this area last autumn, we have found carotene contents equivalent to about 6,000 I.U. of vitamin A per 100 gm. Tests on samples of several other species kindly provided by Dr. Melville gave similar results, and the conclusion may be drawn that British rose hips have a vitamin A value similar to that of carrots. The carotene estimations were made by an unpublished method, of which Dr. T. Moore and Dr. Vernon Booth kindly gave us details.
