An important process in the technology of plant oil production by mechanical pressing is wet–heat treatment crushed oilseeds, which oilseed (compressed seed) exposed to saturated vapor and a conductive heat supply. Optimal mode selection based on detailed study physical processes taking place compressed seed increases release, improves its quality indicators, decreases energy consumption. Mathe...

The efficacy of five native botanicals viz., neem, castor, akondo, basok and ata against the seed associated fungi in controlling leaf spot disease black mustard was evaluated. In blotter method, maximum reduction (85.91%) observed seeds treated with (1:1) while neem (1:1), (1:2) castor gave 83.52, 82.59 82.39%, respectively over control. Maximum germination (93%) akondo where supported 92, 92 ...

in this study theeffect ofdrought stress was investigated on grain yield and oil rate and protein percentage of four varieties of castor in the climatic conditions of damghan. the experiment was done in the research farm of damghan islamic azad university(iran)in 2011 assplit plots in a randomized complete block design with three replications. the main plots of drought stress were 5, 10 and15 d...

Studies of the composition vegetable oils are expedient in order to achieve quality product modelling. The goal this research was determine fatty acids using gas chromatography (GC) and antioxidant activity DPPH ABTS spectrophotometric methods. Analysed were castor seed, sunflower sesame fibrous hemp black radish seed olive oils. Different classes determined: polyunsaturated, monounsaturated sa...

Castor bean has not been well studied in different genotypes and geographic zones despite its application industry medicine. Recently, the use of castor beans as biodiesel makes this plant a point interest for researchers. However, more studies are needed evaluating from ecologies. The effect climatic zones, Adana Mersin, on fatty acid profile chaster seed oils was investigated. It found that l...

1. Ricinoleic acid is shown to be synthesized in the immature castor bean seed only after 3-4 weeks from the time of fertilization. 2. Synthesis occurs both in the isolated embryo and the endosperm. 3. Linoleic acid does not act as precursor of ricinoleic acid in the isolated bean embryo. 4. Oleic acid is shown to be the direct precursor of ricinoleic acid. 5. The reaction does not use molecula...

The study was carried out to ascertain the antibacterial properties inherent in fermented seed extracts of Ricinus communis. Dry seeds of R. communis (Castor oil plant) were deshelled, grounded to powder, fermented, and then extracted both with alcohol and water using Soxhlet machine. Different concentrations of the extracts were tested against selected bacteria using diffusion method of suscep...

Medicinal plants have always played a vital role for the healthy human life. The family Euphorbiaceous is a family of flowering plants and contains nearly about 300 genera and 7,500 species. Amongst all, the species Ricinus communis or castor plant has high traditional and modern medicinal values. The individual parts of the plant like the seed, seed oil, leaves and the roots showed their impor...
