We attempted to examine the compositions of seborrheic lipids from the scalp of the human adult males and the patints who have the seborrheic dermatitis by the ?hin layer chromatography(TLC) and the photodensitometer. The human skin surface lipids are composed of the seborrheic lipids from the sebaceous glands and epidermal lipids from the ediermis. The sebaceous lipids were known that they played the role to protect the skin and they had the pathophysiologic role in the seborrheic dermatitis and the ance. We observed that the sebacous lipids were composed of squalene, ??olestrol ester, wax ester, triglyceride, free fatty acid, and saturated hydrocabon in both the control group and the patient group. In the mean values of the ratio of the seborrheic lipids composition, the ratio of squalene and cholesterol eater were higher, and the ratio of free fatty acid and triglyceride were lower in the patient group than in the control group, and the ratio of wax ??ster which was originated from sebaceous glands was no difference between two groups. Thus, n?the seborrheic dermatitis, there was no change in the sebum secertion rate, but the lipid compositions were changed.
