Abstract:

Background: Spathe of date palm (which is called Tarooneh by Persian folk) and its aroma water is widely used in Persian traditional medicine but according to best of our knowledge lack is done on its chemical composition or standardization of the herb for its quality control in herbal market. Methods and material: In this study microscopical and preliminary pharmacognostic properties of fractions obtained from date palm spathe (Tarooneh) were screened by thin layer chromatography. In addition, essential oils of the spathe were analyzed by GCeMS spectroscopy. Results: Different fractions of the spathe contain steroids, triterpene steroids, oils and flavonoids in different amount. Fourteen compounds accounting for 93% of the oil were identified by GCeMS analysis. Oxygen containing monoterpenes were the main class of components (73%) with carvacrol (37%), linalool (24%) and thymol (10%) as major constituents of the oil. Conclusion: Volatile constituents and preliminary pharmacognostic evaluation of Tarooneh can give some useful data for further phytochemical analysis, quality control and standardization of Tarooneh.

Key words: Date palm, GCeMS, Phytochemical screening, Spathe, Volatile oil.
