Pharmacognostic Standardization of Cymbopogon citratus (dc.) stapf leaves

Abstract

2'-O-rhamnoside [10] and isolation of the flavonoids quercetin, kaempferol and apiginin [11] from aerial parts. The phenolic compounds elimicin, catecol, chlorogenic acid, caffeic acid and hydroquinone isolated from plant. [12] Various pharmacological activities of Cymbopogon citratus, have been reported such as Anti amoebic, [13] Antibacterial, [14-17] Antidiarrhoeal, [18] Antifungal, [19] Antimalarial, [20] Antiinflammatory [21] and Anti-anxiety. [22] Cymbopogon citrates (DC) Stapf (Graminae) (C. citratus) are an herb worldwide known as lemongrass. The tea made from its leaves is popularly used as antispasmodic, analgesic, anti-inflammatory, antipyretic, diuretic and sedative. [28] In lemongrass, antioxidant [29] , and antinociceptive [30] activities have been studied. A few ethno botanical reports on treatment of fever and headache were investigated. [23] MATERIALS AND METHODS

Absence of Renal Protection of an Aqueous Extract of Lemongrass (Cymbopogon citratus) Cultivated in Costa Rica, Using a Model of Acute Renal Failure in Wistar Rats

“…These results were also reflected in the phytochemical tests of ferric chloride, Shinoda and Wilson, as they were negative for the three cases. This coincides with previous studies where flavonoids and found and a small amount of phenols has been observed in the aqueous extract 33,34 .…”

Alteraciones histopatológicas causadas por la roya Puccinia nakanishikii (Pucciniales: Pucciniaceae) en plantas de Cymbopogon citratus (Poaceae)

“…En investigaciones previas se ha determinado que las hojas de C. citratus son principalmente hipostomáticas de simetría dorsiventral, con estomas de amplias cavidades subestomáticas formando filas paralelas a las venas, y tricomas espinosos unicelulares, así como, microtricomas bicelulares, y densas ceras epicuticulares principalmente sobre la superficie abaxial; en tanto que la superficie adaxial está formada principalmente por agrupaciones de células buliformes y células epidérmicas alargadas o cortas de contorno rectangular a cuadrado en sección trasversal y con escasos tricomas (Metcalfe, 1960;Bertea & Maffei, 2010;Eltahir & Abuereish, 2010;Shah, Kaur, Dhabiliya, & Shri, 2012;Kellogg, 2015). Estas características de las hojas descritas por estos autores son similares a lo observado en esta investigación para C. citratus, aunque con ligeras diferencias, como la presencia ocasional estomas sobre la superficie adaxial de la lámina foliar.…”

“…CB: células buliformes; EB: epidermis abaxial; ED: epidermis adaxial; ES: estomas; FL: floema; HD: haces vasculares de mayor diámetro; HM: haces vasculares de menor diámetro; OS: ostiolo; PC: paráfisis capitadas; PF: parénquima fotosintético; PI: picnidios; PIE: picnidiosporas libres; PX: protoxilema; UE: urediospora; US: urediosoro. C 4 o Kranz característico de esta gramínea y la cual es consistente con la presencia de una banda uniestratificada radial de parénquima fotosintético con cloroplastos en posición centrifuga, principalmente alrededor de los haces vasculares de menor diámetro, es congruente con lo registrado en la literatura para esta especie y otras monocotiledóneas que tienen este mismo tipo de metabolismo (Metcalfe, 1960;Bertea et al, 2003;Bertea & Maffei, 2010;Eltahir & Abuereish, 2010;Shah, Kaur, Dhabiliya, & Shri, 2012;Lundgren, Osborne, & Christin, 2014;Kellogg, 2015).…”

Molecular, Chemical and Microscopic Analysis of Medicinal Plant (<i>Cymbopogon distans</i>) from Its Adulterants

“…Previous studies have reported that microscopic assessment to be helpful for the quality control of plant species including C. citratus and discrimination from drugs and adulterants [36]. E.L. Kotina et al [37] studied the anatomical characteristics of leaves of Warburgia salutaris (Canellaceae).…”
