As a result of human activity, longleaf pine (Pinus palustris Miller) forests in the southern United States have been lost or drastically altered. Many of the plant species that historically occupied those forests now persist only as remnants and are classified as threatened or endangered. In order to safeguard such species, a better understanding of their pollination ecology is needed. We iden...

Abstract Narciclasine is a 7-hydroxy derivative of lycorisidine. It was the first alkaloid isolated from stem narcissus (Amaryllidaceae) in 1967. Six mice were given narciclasine (5 mg/kg) by intravenous administration. A UPLC-MS/MS method developed to determine mouse blood. Tectorigenin (internal standard, IS) and gradient eluted mobile phase methanol 0.1% formic acid BEH C18 column. The multi...

Background: Crinum purpurascens is a herbaceous plant belonging to the Amaryllidaceae family. We aimed to evaluate the antisalmonellal properties of the leaf extracts and fractions of C. purpurascens, and the toxicity of the most active extract. Methods: Three extracts and three fractions were prepared from the leaves of Crinum purpurascens Herb. (Amaryllidaceae) and tested for their antisalmon...
