Seed flavonoids profile of Calligonum L. in Sothern Khorasan Provine , Iran

Introduction: Calligonum L. (Calligoneae -Polygonaceae), with about ۸۰ species in the world and ۲۳ recorded species in Iran. It is a novel report and presents flavonoids profile of nine Calligonum species (C. bungei Boiss, C. comosum L.Her., C. crinitum Boiss., C. junecum Fisch et Mey. C. microcarpum Borszcz., C. microcarpum Borszcz., C. paletzkianum Litw., C. persicum Boiss & C. turkestanicum Korov.) from Southern Khorasan Province, Iran for understanding these compounds roles as biological active compounds present in plants used for food and medicine. Materials and methods: All samples were examined to practice flavonoid detection, isolation and identification by ۲-dimensional paper chromatography (۲-DPC), thin layer chromatography (TLC), UV spectroscopy and available references. Voucher specimens were prepared for reference as herbarium voucher that kept in Arak University Herbarium. Results and Discussion: Results showed all examined taxa contain flavones C and C-/O glycosides, kaempferol and quercetin. All of them exceptional C. microcarpum had aglycones. Flavonoid sulphates found in ۵ species and hesperidin was just in C. crinitum. Narangenin and morin were not found in any of the species. Conclusion: This study showed that the number, type and variety of seed flavonoid compounds are valuable in the diagnosis and separation of taxa.
