Optimization of Green Synthesis of Silver Nanoparticles from Leaf Extracts of Pimenta dioica (Allspice)

Production of silver nanoparticles from the leaf extracts of Pimenta dioica is reported for the first time in this paper. Three different sets of leaves were utilized for the synthesis of nanoparticles-fresh, hot-air oven dried, and sun-dried. These nanoparticles were characterized using UV-Vis spectroscopy and AFM. The results were diverse in that different sizes were seen for different leaf c...

Anticancer and antioxidant tannins from Pimenta dioica leaves.

Two galloylglucosides, 6-hydroxy-eugenol 4-O-(6'-O-galloyl)-beta-D-4C1-glucopyranoside (4) and 3-(4-hydroxy-3-methoxyphenyl)-propane-1,2-diol-2-O-(2',6'-di-O-galloyl)-beta-D -4C1-glucopyranoside (7), and two C-glycosidic tannins, vascalaginone (10) and grandininol (14), together with fourteen known metabolites, gallic acid (1), methyl gallate (2), nilocitin (3), 1-O-galloyl-4,6-(S)-hexahydroxyd...

Pharmacognostic Standardisation of the Leaves of Pimenta Dioica Linn

Pimenta dioica commonly known as Allspice was used by early Central American civilizations as a flavoring for chocolate and found to have good anti-microbial action. The current study was therefore carried out to provide requisite pharmacognostic details about the plant. The results of the study could be useful in setting some diagnostic indices for the identification and preparation of a monog...

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...
