Essential oil


If my compound comprises 12% of my essential oil,


How much compound is there in 10mL, in milligrams?

Be more specific, what compound, what essential oil? Without this information we can only give a very rough guess. Based on your information, I would say at most 1 gram, but more accuracy cannot be given.

it contains x mg

x = 10 * (oil density) * 12 / 100 * 1000

oil density is 0.8 to 0.9

Knowing that about say 12% of the essential oil is the myristicin

Hopefully m/m% %m/v is nonsense, and should be avoided, especially in non-aqueous mixtures.

%m/v may look gross from a pedantic perspective, but it is very useful! It’s far more practical than m/m or v/v when it comes to making stock solutions of reagents, since you’ll know exactly how much mass of the diluted reagent you have in an easily measurable volume of solution. No fussing about with densities or weighing out liquids. Of course, most of the time, a molar solution is even more practical, but %m/v and M can be easily interconverted.

% should be always by weight so measure out 10 ml, weigh it and multiply by 0,12 and you have the weight of your mystery oil fraction.

I think the % of myristicin i nutmeg essential oil varies quite a bit for batch and different suppliers.
I have seen many papers where the amount has been different i all of them.
So unless you have a measurement of this specific batch from the supplier the best would be to do a fractional vacuum distillation and see what you get.
If there isnt any other fractions with similar boiling points, then you have to get creative to isolate it.
