Cinerarin, the anthocyanin isolated from the blue flowers of garden cineraria, S. cruentus by Yoshitama et al. [1, 2], was identified as dicaffeylated delphinidin 3,7,3'-triglucoside on the basis of the chemical evidences and its extraordinary sta­ bility in a neutral aqueous solution was also point­ ed out. Goto et al. [3] established its complete structure as malonyltricaffeyl delphinidin-tet...

Alkaloid profiles of two Egyptian Senecio species (Senecio aegyptius var. discoideus and S. desfontainei) in addition to a cultivated species (S. cineraria) were studied using capillary GLC and GLC-mass spectrometry with respect to pyrrolizidine alkaloids (PAs). Four alkaloids were identified in S. aegyptius var. discoideus, 8 in S. desfontainei and 13 in S. cineraria. Some of these alkaloids h...

Due to rapid industrialization and urbanization, environmental pollution has become a significant concern in developing countries; therefore, the main objective of the current study is to determine some of the heavy metal (HM) concentrations in the leaves of dusty miller (Cineraria maritima) and purstane (Mesembryanthemum cordifolium) in different general bus terminal along with the green space...

Centaurea solstitialis, commonly known as yellow starthistle, is an invasive plant listed as a noxious weed in the western areas of North America and is the target of classical biological control, which involves release of herbivores known to be specific to this plant. These insects often choose their host plant on the basis of the volatile organic compounds (VOCs) emitted. Accordingly, volatil...

Alnus maritima and Alnus serrulata are riparian shrubs that occur in similar habitats in the southern and eastern United States.Alnus serrulata is abundant throughout this range, but A. maritima is rare, occurring only in small populations in Oklahoma and Georgia and on the Delmarva Peninsula. Alnus maritima is more resistant than A. serrulata to water and temperature stresses, but the degree t...
