Donkey oil? What's that???
I found this:
The roots of Angelica sinsensis contain between 0.4% to 0.7% volatile oils and includes;
n-valeropheneone-O-carboxylic acid, carvacrol, safrole, butylidene phthalide, sesquiterpenes,
n-butylphalid, dodecanol, tetradecanol, nicotinic acid, myristic acid, folinic acid and ligustilide.A better answer might be in this ref:
Fang HJ, Lu RM, Liu GS, Liu TC.
[Studies on the components of essential oils. II. Comparison of the major
constituents of the essential oil from two species of Dang gui (Angelica sinensis
(Oliv.) Diels and Levisticum officinale Koch (author's transl)].
Yao Xue Xue Bao. 1979;14(10):617-23.
Chinese. No abstract available.Or maybe
Lin M, Zhu GD, Sun QM, et al, "Chemical Studies of
Angelica sinensis," Yao Hsueh Hsueh Pao, 1979,
14(9): 529-34.
Sorry. Best I could find.
