since nerol is a valuable constituent of ** synthetic rose oil," the oil of
helicbrysam should prove a valuable commercial source of this. Nerol
has a rose-like odor, and has been found, in small quantities only, in the
oils of neroli, petit-grain, rose and lignaloe. To obtain pure nerol, the
saponified oil is treated with phthalic anhydride or the anhydride of a
dibasic acid, with which it forms acid esters. These are either separated
by saponification and shaking out with immiscible solvents, or by fraction-
ation in vacuo; or the nerol is converted into Purchase Hoodia Online the benzoic ester, and sep-
arated from the more volatile bodies which accompany it by fractional
distillation under reduced pressure. Pharm. Joum. and Pharmacist, July

In connection with the preceding it is interesting to note some observa-
tions made by Ernest J. Parry in an article on adulterated petitgrain oil
(which see), which Purchase Hoodia Online evidently refer to the adulterant mentioned by Mr.
Umney. Mr. Parry says that manufacturers of terpineol appear Purchase Hoodia Online to accumu-
late a large amount of residues which contain the oxidation and other
alteration products of turpentine formed during the course of terpineol-
mannfacture. This oil can be obtained for a few pence per lb., and is a
Tiscons oil, containing a fair amount of free alcoholic substances, of high
specific gravity (up to 0.930) and various hydrocarbons. It has not yet
