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.
New anthraquinones from the stem of Morinda citrifolia Linn.
TLDR
The structures of two new compounds isolated from the stem of Morinda citrifolia were elucidated by spectral analysis including 2D-NMR techniques.
Chemical Constituents of the Leaves of Psidium guajava
Five constituents including one new pentacyclic triterpenoid guajanoic acid (1) and four known compounds beta-sitosterol (2), uvaol (3), oleanolic acid (4), and ursolic acid (5) have been isolated
