Brit.

/mɛnɪˈanθɪn/, U.S.

/mɛnɪˈænθ(ə)n/

Forms: 1800s menyanthine, 1800s– menyanthin.

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin Menyanthes , -in suffix¹.

Etymology: < scientific Latin Menyanthes, the name of the genus of plants including the buckbean (J. Pitton de Tournefort Inst. Rei Herbariæ (1700) I. 117; see below) + -in suffix¹. Compare French ményanthine (1842).Post-classical Latin menyanthes is condemned as erroneous in a 1557 edition of a Latin translation of Nicander; it is < Hellenistic Greek μινυανθές , the name of a different trifoliate plant, the pitch trefoil, Psoralea bituminosa (use as noun of μινυανθής blooming a short time < ancient Greek μινυ- , base of μινύθειν to diminish (see minor adj.) + ἄνθος flower: see anthos n.), with men- representing μιν-, perhaps as a result of confusion with Hellenistic Greek μηνάνθος dwarf water lily, Limnanthemum nymphoides. Compare French menianthes (1615).

Chemistry.

A bitter glycoside, C₃₃H₅₀O₁₄, contained in the leaves of the buckbean, Menyanthes trifoliata.

1850 J. Ogilvie Imperial Dict. at Menyanthes It contains an extractive called menyanthine.

1897 Naturalist 45 The most palpable ingredient of the plant is a bitter principle menyanthin.

1931 M. Grieve Mod. Herbal I. 117/2 The chief constituents are a small quantity of volatile oil and a bitter principle, a glucoside called Menyanthin.

1964 Jrnl. Ecol. 52 729 Grazing by sheep and cattle has been noted..when other feed is in short supply; it is not taken at other times perhaps because of the glucoside (menyanthin) the plant contains.
