Vitamin C Content of Wild Greens1

Hazel C. Murray and Robert Stratton

Departments of Home Economics Research and Botany, Oklahoma Agricultural and Mechanical College, Stillwater

Vitamin C assay of fresh, cooked, and frozen samples of edible wild greens showed that pokeweed, tall dock, and curly dock contained twice as much of this vitamin as spinach; poverty weed, shepherd's purse, and lamb's quarter about as much as spinach; chickweed, dandelions, and prickly lettuce considerably less than spinach. Loss of vitamin C in wild greens due to freezing or cooking was comparable to the loss sustained under similar conditions by cultivated greens. There was some indication that the vitamin C content was greater in plants exposed to full sunlight and in fertile, uncultivated soil.

1 The work reported here was carried out under a joint project of the Oklahoma Agricultural Experiment Station, and the School of Arts and Sciences of the Oklahoma Agricultural and Mechanical College.

Manuscript received 7 August 1944.
