Comparative Morphological and Anatomical Study of Onosma caucasica Levin. ex M. Pop. and Onosma sericea Willd. (Boraginaceae Juss.)

Abstract

Introduction: Finding sources of drugs among the species of genus Onosma of the local fl ora is actual direction. Many of the species of genus Onosma are weeds, some live exclusively on dry sandy or rocky slopes. Many of the species of genus Onosma have used in ethnopharmacology as anti-infl ammatory, analgesic, and wound health remedies. The purpose of this research is morphological and anatomical study of herbs of Onosma caucasica Levin. ex M. Pop. and Onosma sericea Willd. (Boraginaceae). Materials and Methods: The objects of the study were collected in North Caucasus (Russia) in June 2011. Materials morphological study herbarium specimens were stored in the herbarium fund the Department of Botany (acronym PGFA). Materials micromorphological study were temporary slides are the leaf, stem and fl owers. Results: The morphological results were compared with the Flora of the USSR. Anatomical characters of leaves and stems of the species were observed to be similar to the usual features of Boraginaceae anatomy. All results are supported by photographs. The nature of trichomes on the leaf blade has a major diagnostic value in determining the authenticity of herbs the studied species. Conclusion: The severity of downy leaf blade and the corolla, and the structure of the hair can reliably identify this type of raw material and serve as the basis for the development of the regulatory documentation for its standardization.

Pollen morphology and systematic significance of some Onosma L. species (Boraginaceae) distributed in pan Himalayan regions

“…Many species of the Onosma L. have been used in ethnopharmacology and the ethanol extract of some species has been reported to have anti-inflammatory and analgesic properties. Some are used for other health remedies, treatment of wounds, as herb, traditional medicine and dyes (Özgen et al, 2003;2004;Naz et al, 2006;Tosun et al, 2008, Kumar et al, 2013Daironas et al, 2014;Imran et al, 2018). The floral parts of some species are edible and taken as vegetables (Öztürk & Özçelik, 1991).…”

“…Different studies related to morphological, micromorphological, anatomical, ecological, karyological, molecular and palynological characteristics of Onosma species have been carried out (Teppener, 1971;Azizian et al, 2000;Vauillamoz, 2001;Bigazzi & Selvi, 2000;Akçin & Engin, 2001;2005;Akçin, 2004;2007a;2007b;2009;Martonfi et al, 2008;Peruzzi & Passalacqua, 2008;Kolarcik et al, 2010;Akcin & Binzet, 2010;2011;Binzet & Akçin, 2009;Binzet & Orcan, 2003a;2003b;2009;Binzet, 2011;Rajanbar & Almasi, 2013;Arabmeri et al, 2014;Daironas et al, 2014;Kolarcik et al, 2014;Mehrabian et al, 2014;Almasi & Rajanbar, 2015;Teke & Binzet, 2014;Mehrabian et al, 2017 andBinzet et al, 2018). However, the systematics of Onosma still has not been fully resolved and needs more attention.…”
