: So what are all these different "terps" and why don't certain oils

: darkening henna? Help!

I think the trick is to find out exactly which terpene works.
Different elements do different things. Frankincense (and others, I'm
certain) has particular terpenes (mono, di and whatnot) that possibly
act upon the henna in a different manner.

Here's some info:

<<Terpenes- A group of unsaturated hydrocarbons present in plants
(see essential oil). Terpenes consist of isoprene units, CH2:C(CH3)
CH:CH2. Monoterpenes have two units, C10H16, sesquiterpenes three
units, C15H24, diterpenes four units, C20H32, etc. Terpenoids, which
are derivatives of terpenes, include abscisic acid and gibberellin
(plant growth substances) and the carotenoid and chlorophyll
pigments.>>

<<Brief Introduction to Essential Oil Chemistry
Essential oils are made up of many chemical constituents. No two oils
are alike in their structure or their effects. Below is a list of
some of the main constituents found in essential oils:
· Alcohols
· Aldehydes
· Esters
· Ethers
· Ketones
· Phenols
· Terpenes

Each of these can be broken down into numerous smaller units. Take
terpenes, for example. This classification includes monoterpenes,
sesquiterpenes, sesquiterpene lactones, Di-terpenes, etc.>>

<<TERPENES : Any of a group of hydrocarbons that are made up of
building blocks of isoprene (C5H8) or similar five- carbon units,
with a monoterpene made up of two units (example: limonene and
pinene), a sesquiterpene made up of three units (example: humulene, a
Hops aromatic), and a diterpene made up of four units.>>

<<Terpenes
Terpenes are widespread in nature, mainly in plants as constituents
of essential oils. Many terpenes are hydrocarbons, but oxygen-
containing compounds such as alcohols, aldehydes or ketones
(terpenoids) are also found. Their building block is the hydrocarbon
isoprene, CH2=C(CH3)-CH=CH2 (isoprene rule, Wallach 1887). Terpene
hydrocarbons therefore have molecular formulas (C5H8)n, they are
classified according to the number of isoprene units:

number of isoprene units
monoterpenes 2
sesquiterpenes 3
diterpenes 4
triterpenes 6
tetraterpenes 8

Examples of monoterpenes are: pinene, nerol, citral, camphor,
menthol, limonene. Examples of sesquiterpenes are: nerolidol,
farnesol. Examples of diterpenes are: phytol, vitamin A1. Squalene is
an example of a triterpene, and carotene (provitamin A1) is a
tetraterpene.>>

<<Terpenes: An enormous group of plant hydrocarbons formed by the
polymerization of 5-carbon isoprene (C5H8) subunits. Terpenes are one
of the largest and most varied group of plant chemicals. They may
contain carbon chains and rings in different structural forms called
isomers. They may also be reduced and oxidized into a vast array of
compounds, including alcohols, ketones, acids and fragrant aldehydes.
There are five main types of terpenes, including 10-carbon
monoterpenes (2 isoprenes), 15-carbon sesquiterpenes (3 isoprenes),
20-carbon diterpenes (4 isoprenes), 30-carbon triterpenes (6
isoprenes) and 40 carbon tetraterpenes (8 isoprenes). >>

This site http://shell.rmi.net/~grymntl/bos/herb/essenc.html gives an
interesting tech data summary. And this site
http://dspace.dial.pipex.com/town/avenue/as07/chemistry.htm gives
some very good basic info and drawings and is aimed at aromatherapy.
Kind of a nicer focus than industrial grade cleaning supplies!

Lastly, this site
http://orbital.chem.utas.edu.au/teaching/KRA305/biosynthesis/ubstpfile
s/ubstpall.htm gives more info that I can summarise!
A 'pop' quiz will follow!
