SUMMARY— By means of thin‐layer chromatography, gas‐liquid chromatography and chemical analyses the following substances were identified in dried Iceberg lettuce ( Lactztca sativ L.): ceryl alcohol, β‐sitosterol, stigmasterol, campesterol and the glycosides of the latter three sterols. An unidentified substance, probably a sterol, was detected by gas‐liquid chromatography. A mixture of triterpenes identified as containing β‐amyrin, ã‐amyrin and Ψtaraxasterol was also found.
