Resveratrol and its derivatives are natural stilbenes associated with many health benefits that include those conferred by their antioxidant and anticancer properties. While stilbenes can be recovered as an extract from a selected number of plants, these products are not suitable for many applications in the food/pharmaceutical sectors due to high levels of impurities as well as the overall low...

This research was designed to determine what components of Gardenia jasminoides play a major role in inhibiting the enzymes related antidepressant activity of this plant. In our previous research, the ethyl acetate fraction of G. jasminosides fruits inhibited the activities of both monoamine oxidase-A (MAO-A) and monoamine oxidase-B (MAO-B), and oral administration of the ethanolic extract slig...

Phytochemical and bioactivity studies of the flowers of Melastoma malabathricum L. (Melastomataceae) have been carried out. The ethyl acetate extract yielded three compounds, identified as naringenin, kaempferol and kaempferol-3-O-d-glucoside, and methanol extract gave kaempferol-3-O-(2′′,6′′-di-O-p-trans-coumaroyl)glucoside and kaempferol-3-O-d-glucoside. The crude extracts and isolated compou...

The potential energy surface of acetylsalicylic acid, aspirin, has been explored at the RHF/6-31G* and B3LYP/6-31G* levels, and single-point calculations were performed at levels up to B3LYP/6-311G**//B3LYP/6-31G*. All conformational isomers have been located, the thermochemical functions have been computed, and relative energies and free enthalpies were determined. The conformational space of ...

The methanolic leaf extract of Artemisia parviflora (APLE) tested against Anopheles stephensi larvae and pupae and recorded the mortality rate, LC 50 and LC 90 values. This investigation revealed that this leaf extract possess higher toxicity against Anopheles stephensi. The biological activity of the plant extract might be due to the presence of active compounds âCaryophyllene, germacrene D, C...

The demand for Ceylon cinnamon (Cinnamomum verum syn. C. zeylanicum ) is consistent due to its superior characteristics. Besides that, Sri Lanka home seven other wild species: Cinnamomum capparu-coronde, citriodorum, dubium, litseifolium, ovalifolium, rivulorum, and sinharajaense. Since bark contains more than seventy bioactive compounds, it possesses various pharmacological health benefits, in...

In the hydrated title complex, [Mn(C(8)H(6)N(3)O(2))(CH(3)CO(2))(C(12)H(8)N(2))(H(2)O)(2)]·2H(2)O, the Mn(II) atom is coordinated by two N atoms from a 1,10-phenanthroline ligand, two water O atoms, a monodentate acetate anion and an O-monodentate 2-(1H-benzotriazol-1-yl)acetate ligand, resulting in a distorted cis-MnN(2)O(4) octa-hedral coordination geometry. The water O atoms are in a trans a...
