  Background & Aim: Fruits from the jujube plant (Ziziphus jujuba) possess health-promoting effects and medicinal properties. Jujube has a long history of usage as a remedy in Iranian traditional medicine and is recommended for the treatment of some diseases. This study investigated the variations in antioxidant capacities (AOX), total phenol (TPH), total flavonoid (TF) and total anthocyanin (TA) contents of fruit extracts among 29 jujube accessions originating from 7 provinces of Iran. Experimental: The fruits from 29 accessions were extracted with methanol (85%). DPPH assay were performed for determination of antioxidant capacity of each extract. The total phenols were measured by Folin-Ciocalteu method and total flavonoids evaluated using the aluminum chloride colorimetric procedure while total anthocyanins were determined by pH-differential method. Results & Discussion: The results from the analysis of variance (ANOVA) revealed that the examined accessions of Z. jujuba were highly variable in all evaluated phytochemical traits (P <0.01). Principal component analysis (PCA) based on four phytochemical characters confirmed this broad variation and also identified three distinct group among the accessions. The accessions Hamidabad (Mazandaran), Bayaziyeh (Isfahan) and kuhpayeh2 (Isfahan) can considered by their high values for the TPH, TF, and TA values, respectively. On the other hand, accessions Ardestan (Isfahan), Ghaziolya (Ghom) and Maroon (Ghom) showed high AOX. No correlation was found between total phenol content and antioxidant activity. Industrial and practical recommendations: These findings suggest the importance of genotype and origin for determining antioxidant potential and phenolic contents of jujube plants. The knowledge of the diversities, found in this study, will allow a better plant exploitation related to pharmaceutical uses and also a better conduction of breeding programs for Ziziphus jujubaecotypes.

  Background & Aim: Saffron is one of the expensive spices known since antiquity for its color, flavor and medicinal properties. Saffron is the dried stigma of crocus sativus plant. The three basic components of the stigma on which the qualitative characteristics of Saffron depend are crocin (color), picrocrocin (taste), and safranal (aroma). The quality of saffron is a function of climatic conditions, soil type, as well as method of drying, packaging, and storage. Experimental: In this research, the saffron growing in different regions of Iran including Kerman, Shiraz, Arak, Natanz, Ghaen, Shahrekord, and Dolatabad has been studied with regard to its humidity, ash, phenolic compounds, crocin, safranal, and picrocrocin for its classification. Results & Discussion: The saffron of Shiraz and that of Kerman showed the maximum and minimum amount for ash with a value of 8.02% and 5.38%, respectively. With a view to moisture content, Natanz and Shahrekord saffron showed the highest and the lowest moisture content with a value of 11.97% and 9.7%, respectively. The phenolic compounds were determined by spectrophotometry and ranged from 17.43 mg gallic acid/g dry weight of saffron in Kerman sample to 8.87mg gallic acid/g dry weight in Dolatabad saffron. The highest level of safranal, crocin, and picrocrocin belonged to Shahrekord, Dolatabad, and Shahrekord saffron with a rate of 84.43, 234.4 and 38.4 (strength/ g dry matter) based on the most absorption over three wavelengths of 257, 440, and 330nm, respectively. Industrial and practical recommendations: With regard to variable applications of saffron as flavoring and coloring in food industry, the results of this study can be used for appropriate usage of saffron cultivated in different regions according to their specifications.
