Chemosystematic studies of Nitraria retusa and selected taxa of Zygophyllaceae in Egypt

Flavonoid constituents of Dobera glabra leaves: amelioration impact against CCl 4 -induced changes in the genetic materials in male rats

“…Their structures were elucidated by chemical and spectroscopic techniques (Mabry et al 1970;Agrawal & Bansal 1989;Markham & Geiger 1994), and identified as isorhamnetin-3-O-b-glucopyranoside-7-O-a-rhamnopyranoside (1), isorhamnetin-3-O-a-rhamnopyranoside-7-Ob-glucopyranoside (2), kaempferol-3,7-di-O-a-rhamnopyranoside (3), isorhamnetin-3-O-b-glucopyranoside (4), kaempferol-3-Ob-glucopyranoside (5), isorhamnetin (6) and kaempferol (7). Spectral data of the isolated flavonoids were consistent with those previously published (Beninger et al 1998;Hussein et al 2009Hussein et al , 2011Yi et al 2011).…”

Comparative floral structure and development of Nitrariaceae (Sapindales) and systematic implications

“…In Tetradiclis , the fl owers are always completely isomerous (and therefore completely polysymmetric), independently of whether they are tetramerous or (more rarely) trimerous, and they have a single whorl of (antesepalous) stamens and antepetalous carpels (this study ;Engler, 1931 ). In contrast, in Nitraria and in Peganum , the fl owers have a pentamerous perianth and androecium, with fi fteen stamens and a trimerous gynoecium (this study ;Payer, 1857 ;Baillon, 1873 ;Eichler, 1878 ;Engler, 1931 ;Nair and Nathawat, 1958 ;Kapil and Ahluwalia, 1963 ;Ronse De Craene and Smets, 1991 ;Hussein et al, 2009 ). Most notably, in both genera the 15 stamens are not arranged in two whorls as described by some earlier authors, but they form fi ve triplets with a primary antesepalous stamen fl anked by two secondary stamens.…”

“…Earlier comparative studies also indicated that these four genera, especially Nitraria and also Peganum (with Malacocarpus ), were more distinct from the remainder of Zygophyllaceae than previously suggested (for vegetative anatomy , see Sheahan and Chase, 1993 ; for palynology, see Erdtman, 1952 ;Agababyan, 1964 ;Perveen and Qaiser, 2006 ; for embryology, see Mauritzon, 1934 ;Sou è ges, 1953 ;Kapil and Ahluwalia, 1963 ;Kamelina, 1985Kamelina, , 1994Li and Tu, 1994 ; for fl oral structure, see Baillon, 1873 ;Nair and Nathawat, 1958 ;Ronse De Craene and Smets, 1991 ; ; for chemistry, see Hussein et al, 2009 ). In contrast to most of the current Zygophyllaceae, which have pentamerous, isomerous and obdiplostemonous fl owers, the fl owers in Tetradiclis are tetramerous, isomerous and haplostemonous , while in Nitraria and Peganum (+ Malacocarpus ), the fl owers have a pentamerous perianth and androecium, conspicuous antepetalous stamen pairs and a tricarpellate gynoecium (Payer, 1857 ;Baillon, 1873 ;Engler, 1896aEngler, , b , 1931Ronse De Craene and Smets, 1991 ;.…”

Ethnobotanical study and phytochemical screening of six medicinal plants used in traditional medicine in the Northeastern Sahara of Algeria (area of Ouargla)

“…retusa (Zygophyllaceae) known locally as "Ghardaq" in folkloric medicine of Ouargla was used by the traditional healers as decoction (48.04 %) or powder (39, 22 %) preparation to treat skin (F C = 37.24%) and digestive (F C = 22.76%) diseases. Chemicl study on N. restusa have shown the presence of O-glycosides of flavones and flavonols compounds in addition to flafones c-glycosides which exhibits a notable activity in protecting against oxidative stress (Hussein et al, 2009). Belkadhar (1997) indicated that a decoction of fresh leaves of N. retusa was used in Morocco in case of poisoning, stomach upset, ulcers, gastritis, enteritis, heartburn, colitis, and colonic abdominal pain.…”
