I have a lab manual out. I wrote it because I got tired of teaching labs that were dangerous and generated hazardous waste. It includes labs that can find the L-dopa in Velvet Bean, the alcohol in Orange Extract, the dyes in Kool-Aid, and the Henna in hair dye. (I can now spot henna dyed hair from a great distance.) I have my wonderful research team to thank for their help with this project. It can be viewed and purchased here.here.
