PRELIMINARY AND SHORT REPORT AMOUNT OF ASCORBIC ACID IN NORMAL EPIDERMIS* JOSEPH 0. PRIE5TLEY, M.D.t AND RoscoE C. FOSTER, B.S.t

In undertaking investigations of the function of

grams of skin (wet weight). At that time no satisfactory method was available for separating epidermis from corium without some chemical alteration (1).

ascorbic acid in the skin no reference could be found in the literature concerning the amount of ascorbic acid in epidermis. Jensen and Poulsen in 1942 made an extensive study of the concentration of ascorbic acid in 181 specimens of skin obtained by punch biopsy from 72 persons. They extracted the tissue with 8% mctaphosphoric acid solution

Since then Van Scott has demonstrated that epidermis can be stripped from tbe corium after the skin has been stretched (2). METHOD

Using the same methods described above, ascorbic acid determinations were done in 10 specimens Ascorbic Acid, mg.

Subcutaneous tissue was removed from the corium

by dissection, and the epidermis was separated from the corium by the Van Scott stretch method.

Each specimen of tissue was extracted with 8% metaphosphoric acid solution, the liquid portion decanted and centrifuged, and the supernatant titrated with a standardized solution of 2, 6-dichlorophenol indophcnol.

The amount of ascorbic acid found in the epi-

dermis and corium specimens are listed in Table I.

The amount of ascorbic acid in the epidermis and corium of ten specimens of normal skin was determined. The amount of ascorbic acid found in

and titrated this extract with a solution of 2,6-

dichlorophcnol indophcnol which had been standardized with an aqueous solution of ascorbic acid of known concentration. In 95% of the specimens of normal skin they found concentrations of

the 10 specimens of normal epidermis varied from 5.41 to 13.40 mg. per 100 gm. wet weight, and all

specimens consistently showed much more ascorbic acid in the epidermis than in the corium.
