Abstract

Background: Castor bean (Ricinus communis L.) is one of the most important medicinal plants that used in pharmaceutical, cosmetics and hygienic industries in most of developed countries. The versatile application of castor oil in different industry and recently in food science because of its unique physicochemical properties has led castor oil to be the focus of abundant research projects. Objective: The purpose of this study was to determine, the impact of 7 different climatic conditions in Iran on the castor oil production by castor bean from the standpoints of the quality, oil content and physicochemical properties of castor oil. Methods: Seeds were harvested after ripening and were transferred to laboratory for measurement of physicochemical properties. Tests were included, measurement of either chlorophyll content by spectrophotometer, or refractive index by refractometer, or moisture oil, saponification value, acid value, peroxide value and iodine value by AOCS standards. Results: The results showed that climatic factors had significant effects on oil content, moisture content, acid value, peroxide value, iodine value, chlorophyll content and saponification value. With the analyzed oil samples, oil content, humidity, refractive index, chlorophyll content, saponification value, iodine value, acid value, and peroxide value were respectively determined as 35% - 51%, 0.3% - 1.14%, 1.404 - 1.426, 0.16 - 0.4 mg Phenophytin/ kg Oil, 164 – 1/79 mg KOH/g Oil, 75 - 86 g I2/100 g Oil, 0.29 - 0.6 mg NaOH/g Oil, 0 - 0.5 meq O2/kg oil. Conclusion: Results showed that Urmia, Nazarlu and Marand can be considered for medicinal castor bean plant cultivation for high quality of oil.

Abstract

Anaesthetic effects of essence, water and water-alcohol extractions of clove oil were studied in rainbow trout (Oncorhynchus mykiss), common carp (Cyprinus carpio), Persian sturgeon (Acipenser persicus) and Penaeus semisulcatus under various water quality conditions consisting of water temperature, pH and salinity. The obtained results showed that both water and water alcohol extractions had no anaesthetic effect at concentration upto 2000 mg/L whilst, essence could aet as a suitable anaesthesia at >50 mg/L. The most suitable anaesthic effect by essence in rainbow trout was 250 mg/L provided at 5 C and pH 7. Also, clove oil essence showed the best anaesthetic effect in carp under water quality conditions consiting of water temperature at 25 C and pH 7-8 or water temperature at 30 C and pH 9. In addition, clove oil essence at 75 mg/l and 12 mg/L gave the best anaesthetic and sedation effects in Persian sturgeon provided at 21-23 C and pH 8.3, respectively. Furthermore, clove oil essence at concentrations above 50 mg/L was able to act as an anaesthesia in P. semisulcatus. However, the best anaesthetic concentration was depended on water quality conditions consiting of water temperature, pH and salinity. Iranian Fisheries Science Research Institute Published

Abstract

Background - Damask roses (Rosa damascena Mill.) are mainly used for essential oil production. Previous studies have indicated that all production material in Bulgaria and Turkey consists of only one genotype. Nine polymorphic microsatellite markers were used to analyze the genetic diversity of 40 accessions of R. damascena collected across major and minor rose oil production areas in Iran. Results - All microsatellite markers showed a high level of polymorphism (5-15 alleles per microsatellite marker, with an average of 9.11 alleles per locus). Cluster analysis of genetic similarities revealed that these microsatellites identified a total of nine different genotypes. The genotype from Isfahan province, which is the major production area, was by far the most common genotype (27/40 accessions). It was identical to the Bulgarian genotype. Other genotypes (each represented by 1-4 accessions) were collected from minor production areas in several provinces, notably in the mountainous Northwest of Iran. Conclusions - This is the first study that uncovered genetic diversity within Damask rose. Our results will guide new collection activities to establish larger collections and manage the Iranian Damask rose genetic resources. The genotypes identified here may be directly useful for breeding.
