/ˈˌɑksiəˈkænˌθin/

Forms: 1800s oxyacanthin, 1800s– oxyacanthine.

Origin: A borrowing from German. Etymon: German Oxyacanthin.

Etymology: < German Oxyacanthin (G. Polex 1836, in Arch. der Pharm. 56 266) < post-classical Latin oxyacantha , name for Berberis vulgaris (see oxyacanthous adj.) + German -in -ine suffix⁵. Compare oxyacanthin n. N.E.D. (1904) gives the pronunciation as (ǫ:ksiˌăkæ·nþəin) /ˌɒksɪəˈkænθaɪn/.

1979 Experientia 35 1137/1 An oxyacanthine type dimer was indicated because of the lack of separation between the N-methyl peaks.

1995 Planta Medica 61 74 The benzylisoquinoline alkaloids berbamine and oxyacanthine were more potent inhibitors [of keratinocyte growth] by a factor of three.
