Turmeric (Curcuma longa L.) is an economically important spice and medicinal plant for production of curcuminoids, oleoresin, essential oil which are used in pharmaceutical and cosmetics industries. Presence of these contents in turmeric determine its quality. Average productivity and quality of turmeric is not satisfactory because of the poor genetic materials and non-availability of quality m...

The plant extract mixture (XT) used in the present experiment, containing carvacrol, cinnamaldehyde, and capsicum oleoresin, has previously been shown to decrease diarrhea mortality and to modify the intestinal environment of pigs after weaning. However, results obtained among experiments have not been consistent. We hypothesized that dietary protein could be a main factor determining the effec...

The challenge of finding scale-up criteria that allow reproducing laboratory data at higher scales is extremely important for the industrial supercritical fluid extraction (SFE) processes. The objective of this work is to investigate the scaleup of SFE from Capsicum frutescens pepper using supercritical CO2, and to evaluate the extraction kinetic curves of oleoresin and capsaicinoids of the lar...

The mountain pine beetle, Dendroctonus ponderosae Hopkins 1902, is found in pine forests throughout the western U.S., north to northern British Columbia and Alberta, Canada and south to Mexico. It causes high levels of pine mortality throughout its range. Hosts include many species of Pinus (Pinaceae); in northern California, D. ponderosae is a pest of pine types dominated by P. ponderosa Dougl...

Pinus roxburghii Sarg. (syn. Pinus longifolia Roxb.) (Pinaceae), found in the Himalayan region, furnishes an oleoresin which is used as insecticides, disinfectants and liver disorders. P. roxburghii are reported to have wound healing, cytotoxic, antibacterial, antifungal and spasmolytic actions. The plant also shows beneficial effects in the treatment of cough, ulceration and genito-urinary dis...

Defense-related terpenoid biosynthesis in conifers is a dynamic process closely associated with specialized anatomical structures that allows conifers to cope with attack from many potential pests and pathogens. The constitutive and inducible terpenoid defense of conifers involves several hundred different monoterpenes, sesquiterpenes and diterpenes. Changing arrays of these many compounds are ...

The conifer Picea abies (Norway spruce) defends itself against herbivores and pathogens with a terpenoid-based oleoresin composed chiefly of monoterpenes (C(10)) and diterpenes (C(20)). An important group of enzymes in oleoresin biosynthesis are the short-chain isoprenyl diphosphate synthases that produce geranyl diphosphate (C(10)), farnesyl diphosphate (C(15)), and geranylgeranyl diphosphate ...

The present work carried out to establish the necessary pharmacognostic standards, according to the WHO guidelines for evaluating the plant material of Curcuma pseudomontana J. Graham rhizome. Pharmacognostic parameters such as macroscopic, microscopic, physicochemical constituents, fluorescence analysis, nutritive value, behavior analysis of rhizome powder and TLC studies were performed. Macro...
