 Seeds and carpels of the Japanese star anise contain a convulsant (toxic) principle, [[http://en.wikipedia.org/wiki/Anisatin|anisatin]]. \\

+"The oil of the Japanese star anise tree, Illiciumanisatum Linn., was analyzed by gas-liquid chromatography. The major constituents were found to be cineole (18.1%), linalool (10.1%), methyleugenol (9.8%), α-terpinyl acetate (6.8%), safrole (6.6%), and a sesquiterpene hydrocarbon of unknown constitution (7.2%). The composition of this oil differs widely from that of the commercially used star anise oil obtained from Illiciumverum Hooker. The most striking difference between the two oils is found in the anethole content, which constitutes 88% of the commercial oil but only 1.2% of the oil here investigated." \\

+"Four phenolic compounds were isolated from the leaf oil of Illicium anisatum L. Spectroscopic and synthetic studies showed that they were 1-allyl-2-methoxy-4,5-methylenedioxybenzene [myristicin], 4-allyl-2,6-dimethoxyphenol [6-methoxyeugenol], 1-allyl-3-methoxy-4-(3-methylbut-2-enyloxy) benzene and 1-allyl-3,5-dimethoxy-4-(3-methylbut-2-enyloxy) benzene." \\

-"The essential oil of air-dried Illicium anisatum (Illiciaceae), obtained by hydrodistillation was analyzed by gas chromatography-mass spectrometry (GC-MS). Fifty-two components were identified in the essential oil and the main component was eucalyptol (21.8 %)." \\
+"The essential oil of air-dried Illicium anisatum (Illiciaceae), obtained by hydrodistillation was analyzed by gas chromatography-mass spectrometry (GC-MS)... Eucalyptol (cineole, 21.8 %), sabinene (5.3 %), α-terpinyl acetate (4.9 %), kaurene (4.5 %), isopimaradiene (3.2 %), safrole (2.7 %), linalool (2.6 %), δ-cadinene (2.2 %), α-cadinol (2.2), and terpinene-4-ol (1.9 %) were the main constituents of the essential oil of I. anisatum. In contrast, the main compounds identified by Cook and Howard were cineole (18.1 %), linalool (10.1 %), methyleugenol (9.8 %), α-terpinyl acetate (6.8 %), and safrole (6.6 %). This difference in the main components may be due to the provenance of the plant, harvest time or development stage, extraction technique, or the use of fresh or dried plant material. All of these factors influence the chemical composition and biological activity." \\

+"The volatile compounds from the pericarps of Illicium anisatum L., Illicium brevistylum A.C.Sm., Illicium griffithii Hook.f. & Thomson, Illicium henryi Diels, Illicium lanceolatum A.C.Sm., Illicium majus Hook.f. & Thomson, Illicium micranthum Dunn, and Illicium verum Hook.f. were examined by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The volatiles desorbed from the pericarps of I. verum (Chinese star anise), the species traded for culinary purposes, were generally characterized by a high proportion of (E)-anethole (57.6-77.1%) and the presence of foeniculin; the latter was otherwise only detected in the pericarps of I. lanceolatum. In the pericarps of all other species analyzed, the percentage composition of (E)-anethole was comparatively lower (<or=16.0%). The volatiles desorbed from the pericarps of the toxic I. anisatum (Japanese star anise) were characterized by the presence of asaricin, methoxyeugenol, and two other eugenol derivatives, none of which were detected in any of the other species examined." \\
