In addition to the known compounds erythinasinate [1] and abyssinone V [2], two new flavonoids were isolated from the CHClj extract of the stem bark of Erythrina eriotriocha and characterized by spectroscopic techniques as 3' -ptenylnaringenin [3] and 2'-hydroxy-5'-methoxybiochanin A [4],

The major metabolic pathway for profenofos in cotton involves cleavage of the phosphorothioate ester to yield 4-bromo-2-chlorophenol followed by conjugation with sugars. This investigation found a unique sugar conjugate in cotton stalks and seed. The unique metabolite is identified as a glucosylsulfate conjugate of 4-bromo-2-chlorophenol, and its isolation and structure elucidation are reported. Keywords: Organophosphate metabolism; cotton plants; conjugation reactions; O-glucosylsulfate formation
