Henna (dye)

[Captain_America]

I've been searching but couldn't find any information about the quantitative composition of the OTC dye henna. It is very interesting as it should bee 2-Hydroxy-1,4-naphthoquinone according to an old book, but I have no idea if the OTC product is a pure compound or some mixture. As you can see it is excellent precursor for the making of 2-methoxy analogue of 2C-G-N, it should bee active, don't you think so?

Well, I don't know if the information on 2-Hydroxy-1,4-naphthoquinone is correct, but henna is a brown-red plant material that my girlfriend usess to dye her hairs with. It is therefore not a pure compound, but if the concentration is high enough I guess you could extract the quinone, but it might bee difficult to purify.
