Isolation and structure elucidation of new nitrile and mustard oil glycosides from Moringa oleifera and their effect on blood pressure.
TLDR
This is the first report of the isolation of nitriles, an isothiocyanate, and thiocarbamates from the same plant species.
Hypotensive constituents from the pods of Moringa oleifera.
TLDR
Two new compounds, O-[2'-hydroxy-3'-(2"-heptenyloxy)]-propyl undecanoate and O-ethyl-4-[(alpha-L-rhamnosyloxy)-benzyl] carbamate along with the known substances methyl p-hydroxybenzoate and beta-sitosterol have also been isolated and showed promising hypotensive activity.
Nematicidal constituents of the aerial parts of Lantana camara.
TLDR
Two new constituents, lantanoside and lantanone and the known compounds linaroside and camarinic acid were isolated from the aerial parts of Lantana camara and structures of the new compounds were elucidated by spectroscopic and chemical techniques.
New insecticidal amides from petroleum ether extract of dried Piper nigrum L. whole fruits.
TLDR
The petroleum ether extract of dried ground whole fruits of Piper nigrum L. afforded 20 compounds including two new insecticidal amides named as pipnoohine (1), and pipyahyine (2), seven reported for the first time from this plant, and eleven known compounds, which have been identified through comparison of their spectral data with those reported in literature.
Gastrointestinal, selective airways and urinary bladder relaxant effects of Hyoscyamus niger are mediated through dual blockade of muscarinic receptors and Ca2+ channels
TLDR
Results suggest that the antispasmodic effect of H. niger is mediated through a combination of anticholinergic and Ca2+ antagonist mechanisms, which occur at much lower concentrations in the trachea and bladder.
Isolation and structure elucidation of novel hypotensive agents, niazinin A, niazinin B, niazimicin and niaziminin A + B from Moringa oleifera: the first naturally occurring thiocarbamates
Novel hypotensive principles, niazinin A 1, niazinin B 2, niazimicin 4 and niaziminin A and B 6+7, have been obtained from the ethanolic extract of the fresh leaves of Moringa oleifera, employing a
Hypotensive effect of chemical constituents from Aloe barbadensis.
TLDR
Aloeemodin has emerged as a potent hypotensive agent in current pharmacological investigations and caused 26 %, 52 %, and 79 % falls in mean arterial blood pressure at the corresponding doses of 0.5, 1, and 3 mg/kg in rats.
