Crude venom preparations obtained by drying the contents of paratid glands sea snakes, Laticauda semifasciata (Reinwardt) and laticaudata (Linnaeus), showed strong neurotoxic activity. One hundred pergram percent lethal dose to mice intramuscular injection was 0.5 μg. 0.3μg. per gram body weight mouse for L. laticaudata, respectively. The toxic component in non-dialyzable. It stable when dialyzed against saline, but inactivated water. completely heating at 100°C 15 minutes. treatment with...
Four new alkaloids, alstiphyllanines A−D (1−4), were isolated from Alstonia macrophylla, and their structures determined by MS 2D NMR analyses. Alkaloids 1−4 showed moderate antiplasmodial activity against Plasmodium falciparum vasorelaxant phenylephrine-induced contraction of rat aorta.
A phytochemical study on the bark of Neisosperma oppositifolia (Apocynaceae) yielded two new β-carboline indole alkaloids, oppositinines (1) and B (2), together with five known isoreserpiline, isocarapanaubine, vobasine, 10-methoxydihydrocorynantheol-N-oxide, ochropposinine oxindole. Structural elucidation 1 2 was performed using 2D NMR methods. Oppositinines (2) showed potent vasorelaxant effects rat aorta.
A new diterpenoid alkaloid, sharwuphinine (1) was isolated from the aerial part of Delphinium sharwurense and structure possessing a lycoctonine-type C 19 -diterpenoid alkaloid with nitrone functionality elucidated by spectroscopic analysis.Sharwuphinine showed moderate vasorelaxant activity on rat aorta.Delphinium species have been employed in analgesic balms, sedatives, emetics, antihelminthics folk medicine. 1About twenty are distributed Xinjiang Uygur autonomous region, People's Republic...
The binding ratio of palmitic acid (PA) at the sn-2 position triacylglycerols in infant formulas is lower than that breast milk, resulting higher levels fecal PA. Even if increased to 40–50%, PA formula-fed infants remain those breast–fed infants. In Japan, with 50% or more bound (high milk) are commercially available; however, their effects on excretion have not been investigated. Therefore, this observational study aimed preliminarily evaluate whether feeding volume high milk significantly...
