Surgical silk suture is usually kept at ward after removal of fatty substances and sterilization. We obtained the waxy substances (0.06w/w%) through extracting silk suture with ether, and this is the main crccedure for remcval of fatty substances. The waxy substances are roughly separated into five components by TLC.
We mention the components in order of the Rf value (Up to down)
Spot 1. Normal paraff ins from C16 to C29 were confirmd.
Spot 2. It is presumed to be an ester but that is not confirmd.
Spot 3. It was confirmd that the main component is hexacosylacetate. Besides, acetylyzed compounds of C24∼and C23∼alcohol exist.
Spot 4. Hexacosylalcohol as a main components and the small amounts of C24-and C28-alcohols were confirmd.
Spot 5. It was confirmd that palmitic acid and stearic acid are main components. Besides, fatty aci ds from C20 to C28 are exist.
