Phytochemical investigation of Manitoba plants. I. A new indole alkaloid and associated alkaloids from Phalaris arundinacea

Abstract

Hordenine, gramine, and an unknown con~pound assigned the structure of 2,9-dimethyl-6-methoxy-1,2,3,4-tetrahydro-a-carboline and n-octacosanol were isolated from Phalaris arundinacea Var. Ottawa Synthetic C grown in Manitoba. The compounds were separated by a counter current distribution method followed by column chromatography on Woelm basic alumina, and were characterized by the use of infrared, ultraviolet, mass, and nuclear magnetic resonance spectroscopy.

Comparison of some commercial waxes by gas liquid chromatography

“…The free acids (Table III) were similar in content and composition to those reported by Miet et al (7), and Products 16 18 20 22 24 26 28 30 32 34 Acids 2 1 12 4 1 1 7 32 33 7 Alcohols ------5 ---3 9 65 15 3 octacosanol was the major free alcohol as has been found for leaf waxes of other members of the grass family (23,24). Acids obtained on methanolysis ranged from C 16 to C34, making allowance for the C28-C34 acids contributed by the free acids; the combined acids would be similar to those reported before (7).…”

Palatability of Reed Canary Grass Pasture

“…Good agreement was found between these methods. Our own experience (unpublished), and that of others (Audette et al 1969(Audette et al , 1970Wilkinson 1958) …”

A review of phytoconstituents and biological activities of genus Phalaris

“…Gramine ( 11) is a common indole alkaloid in Poaceae family and was isolated from P. arundinacea and root of P. aquatic and other gramine derivatives (12)(13)(14) were isolated from P. aquatic In addition of two oxindoles alkaloids and one furanobisindole type (20)(21)(22) were found in P. coerulescens, together with tryptamine derivatives (16-19) from P. arundinacea and P. tuberosa. Finally two other classes of alkaloids, phenethyl amine and tetrahydro-β-carboline, (15,23) were found in P. arundinacea [14][15][16][17][18][19][20][21].…”

“…One carbohydrate; inulin (36) was isolated from root of P. arundinacea [24], additionally a fatty alcohol; n-octacosanol (37) was obtained from whole plant of P. arundinacea [16]. β-Sitosterol (38) was found in P. canariensis [25].…”
