Abstract

 An experiment was conducted for phytochemical analysis of the compounds of RHEUM RIBES weedat the PHONOLOGICAL STAGE OF FLOWERING in Weed Science Laboratory of Gonbad-e Qabus University in 2015. Plant samples of RHEUM RIBES were collected from heights of Karizak Village of Kashmar. After identifying the Rheum species, various ORGANS of stem, leaf, and inflorescence were separated from each other, dried and finally powdered. Chemical compounds like the organic matter, ash, CRUD PROTEIN, ADF, NDF, starch, SOLUBLE CARBOHYDRATES, and TOTAL PHENOLS contents of the ORGANS under study and a combination of ORGANS were measured using the standardized phytochemical methods. Results of the variance analysis showed that there were significant differences in the phytochemical traits among various ORGANS of RHEUM RIBES. Findings suggest that the highest percentage of organic matter, ash, CRUD PROTEIN, NDF, and ADF were obtained in the inflorescence, both the stem and leaf, leaf and inflorescence, and stem and inflorescence, respectively. The study also recorded the highest levels of TOTAL PHENOLS in both in floresvence and combination of the ORGANS while the lowest phenols contents were observed in the stem. Results generally showed variations in the content of phytochemical compounds under study in RHEUM RIBES ORGANS. Therefore, regarding high productivity of RHEUM RIBES biomass and the role of phenolic compounds as well as suitable content of some primary metabolites, optimization of suitable method to extract these compounds is necessary.
