16-O-Methylcafestol, a derivative of cafestol, is an isolate of green coffee beans.[1]

This derivative only occurs in the robusta variant of coffee (as opposed to the more expensive arabica, where only cafestol is present). Thus 16-O-Methylcafestol is used as an analytical marker for determining the robusta content of coffee blends.[2]
