c<strong>on</strong>stituent is the isoquinoline alkaloid, magnocurarine (0.15–0.23%).<br />
The presence of liriodendrine has also been reported. The bark also c<strong>on</strong>tains<br />
an essential oil, the major c<strong>on</strong>stituents of which are cadinol (14%),<br />
1,4-cineole (6%), p-cymene (8%), and -eudesmol (17%) and geraniol<br />
(9%), am<strong>on</strong>g others (8, 15–18). The st<strong>ru</strong>ctures of magnolol, h<strong>on</strong>okiol and<br />
magnocurarine are presented below.<br />

Medicinal uses<br />
Uses supported by clinical data<br />
No informati<strong>on</strong> was found.<br />
Uses described in pharmacopoeias and well established documents<br />
Used orally for the treatment of gastrointestinal disorders such as c<strong>on</strong>stipati<strong>on</strong>,<br />
dyspepsia, gastritis, nausea and vomiting. Also used orally to treat<br />
anxiety, coughs and shortness of breath (2).<br />

Treatment of allergic rhinitis, headache, lack of appetite, respiratory c<strong>on</strong>gesti<strong>on</strong>,<br />
neurosis and fever, and as a uterine stimulant (6, 8, 19, 20).<br />
Pharmacology<br />
Experimental pharmacology<br />
Since no clinical studies have directly evaluated Cortex Magnoliae for any<br />
therapeutic c<strong>on</strong>diti<strong>on</strong> and very few pharmacological studies have been<br />
c<strong>on</strong>ducted <strong>on</strong> extracts of the bark, most of this secti<strong>on</strong> describes the pharmacology<br />
and clinical studies of the major chemical c<strong>on</strong>stituents, particularly<br />
magnolol. The correlati<strong>on</strong> of these data to the c<strong>ru</strong>de d<strong>ru</strong>g or its extracts<br />
requires further investigati<strong>on</strong>.<br />
Anti-allergic activity<br />
Oral administrati<strong>on</strong> of 0.01–1.0 g/kg body weight (bw) of an aqueous<br />
extract of the bark dose-dependently inhibited compound 48/80-induced<br />
systemic anaphylaxis in rats (21). At the same dose, the aqueous extract<br />
