Effects of selected reed canary grass alkaloids on in vitro digestibility

Effects of selected reed canary grass alkaloids on in vitro digestibility. Coulman, B. E.; Clark, K. W.; Woods, D. L. (Dep. Plant Sci., Univ. Manitoba, Winnipeg, Manitoba, Can.). Can. J. Plant Sci., 57(3), 779-85 (English) 1977. CODEN: CPLSAY. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Section cross-reference(s): 4 A range of concns. of pure samples of the alkaloids, gramine (I) [87-52-5], hordenine [539-15-1], 5-methoxydimethyltryptamine [1019-45-0] and N-methyltryptamine [61-49-4] which are normal constituents of reed canary grass were added to in vitro rumen fluid fermns. Powd. cellulose and ground reed canary grass were used as substrates and fermn. periods were 24 and 48 h. No consistent relation was found between the concn. of any of the above alkaloids and in vitro digestion values for either of the substrates or fermn. periods. In other studies, 24- and 48-h in vitro digestions were carried out on reed canary grass clones harvested at early heading and 6-week regrowth. These clones showed a very wide range of I, hordenine and total alkaloid levels. No relation was found between the concn. and type of alkaloids in the clones and their in vitro digestibility. These findings are in keeping with earlier similar work and it was concluded that reported poor animal performance with reed canary grass is probably due to factors other than alkaloid interference with the rumen microflora.

Effect of licorine, hordenine, and hordenine monomethyl ether on the bronchi under normal conditions and during experimentally induced bronchospasm

Effect of licorine, hordenine, and hordenine monomethyl ether on the bronchi under normal conditions and during experimentally induced bronchospasm. Akbarov, Z. S.; Nabiev, A. (USSR). Farmakol. Rastit. Veshchestv, 71-5. Edited by: Sultanov, M. B. Izd. "Fan" Uzb. SSR: Tashkent, USSR. (Russian) 1976. CODEN: 38UUAL. DOCUMENT TYPE: Conference CA Section: 1 (Pharmacodynamics) Hordenine (I) [539-15-1] (0.5-1.0 mg/kg) and its methyl ether [775-33-7] (1 mg/kg) were effective bronchodilators in cats with proserine-induced bronchospasm, but had little effect on normal cats. Licorine (II) [476-28-8] (0.1-0.3 mg/kg) had little effect on proserine-induced bronchospasm, but increased the tonus of bronchial musculature in normal cats. II increased histamine-induced bronchospasm.
