Biological activity of a phloroglucinol glucoside derivative from Conyza aegyptiaca.
The phloroglucinol glucoside derivative [2,4-dihydroxy-6-(beta-D-glucopyranosyloxy)phenyl]-butan-1-one (1), roseoside (2), and kaempferol-3-O-beta-D-glucopyranoside (3) were isolated from the aerial parts of Conyza aegyptiaca (L.). To the best of our knowledge, this is the first isolation of compounds 1-3 from C. aegyptiaca. Their structures were determined by spectroscopic techniques including...
متن کاملInsecticidal Properties and Chemical Composition of Conyza Aegyptiaca (L.) Oil: Studies on Two Dipterous Insect Pests
The herb, Conyza aegyptiaca L., was subjected to hydrodistillation process to extract the essential oil from the whole dry plant material. Larvae and adult stages of the mosquito, Anopheles pharoensis, and the housefly, Musca domestica, were used as test model organisms representing two dipterous insect pests of medical importance. Under standard bioassay test methods, the LC50 of the oil accou...
متن کاملA triterpene saponin from Lysimachia thyrsiflora L.
A triterpene saponoside (LTS-4) isolated from the underground parts of Lysimachia thyrsiflora L. was defined as 3-O-{beta-D-xylopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 4)-[beta-D-glucopyranosyl-(1 --> 2)]-alpha-L-arabinopyranosyl}-cyclamiretin A. Structure assignment was performed on the basis of spectroscopic data including homo- and heteronuclear 1D and 2D NMR (COSY, TOCSY, NOESY, HE...
متن کاملcalcium oxalate crystals in Conyza canadensis (l.) cronq. and Conyza bonariensis (l.) cronq. (Asteraceae: Astereae)
Calcium oxalate crystals (CaOx) are found in most organs and tissues of many plant species. In this study the morphology and distribution of CaOx crystals in Conyza canadensis (L.) Cronq. and Conyza bonariensis (L.) Cronq. belonging to Asteraceae were investigated. CaOx crystals display a similar distribution in organs and tissues of C. canadensis and C. bonariensis. For the identification of C...
