fifty-nine samples of washed and unwashed leaves of 4 species of plants in tehran and 24 similar samples of the suburb (as control) were analyzed for pb content. a significant difference was seen between pb contents of washed and unwashed urban samples, while no significant difference was observed between the control samples. the mean pb contents of the urban suburb samples were also significan...

this study documents the flavonoid constituents of seven salvia species in iran namely s.atropatana bunge, s. limbata c. a. mey, s. sclarea l., s. ceratophylla l., s. multicaulis vahl.,s. hydrangea dc. ex benth., and s. eremophila boiss. the studied species were collected fromtheir natural habitats in iran and were analyzed for their flavonoid constituents using twodimensionalthin layer chromat...

background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...

the dried aerial parts of scutellaria lateriflora l. (family labiatae), have been used for many years as a domestic remedy for epilepsy, hysteria, and nervous tension states. although several phytochemical investigations have been made regarding the constituents present in this species (i. e. flavonoids, iridoids), none has been recorded concerning the cuticular wax. using thin-layer chromatogr...

Living systems, whether organs or entire organisms, display various forms of morphological invariance. Why? These phenomena are studied here from the Proto-Cognitive perspective, according to which evolution proceeds by processing information about the environment. The evolution of constancy, uniformity and symmetry is studied in detail. The study later focuses on the invariances of the plant's...
