The plants of the genus Salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. Eleven Salvia species including S. aegyptiaca, S. aethiopis, S. atropatana, S. eremophila, S. hypoleuca, S. limbata, S. nemorosa, S. santolinifolia, S. sclarea, S. syriaca, and S. xanthocheila ...

eight salvia l. species including s. spinosa l., s. reuterana boiss., s. macrosiphon boiss., s. syriaca l., s. nemorosa l., s. virgata jacq., s. sharifii rech. f. & esfand. and s. mirzayanii rech. f. & esfand. were studied for flavonoid compounds. these constituents were analyzed using two-dimensional maps on silica gel 60f thin layer chromatography. the flavonoid compounds of each spec...

—After defoliation occurs leaf photosynthetic rate (Pn) can increase, decrease or remain unchanged relative to control uninjured leaves depending on the plant species. With common milkweed Asclepias syriaca (Asclepiadaceae) we conducted 27 experiments with insect herbivory or mechanical tissue removal to examine whether A. syriaca leaf Pn reductions were correlated with the occurrence of gross ...

1. Plant-mediated interactions between co-occurring herbivores play an important role in insect herbivore communities. Although induced resistance pathways associated with jasmonic acid and salicylic acid are often implicated in such plant-mediated interactions, there are few examples from non-model systems involving specialized herbivores that regularly interact in nature. 2. Here, we tested r...

In eastern North America, the field milkweed, Asclepias syriaca L. (Asclepiadaceae), is used in planting schemes to promote biodiversity conservation for numerous insects including the endangered monarch butterfly, Danaus plexippus (Linnaeus) (Nymphalidae). Less is known about its pollinators, and especially in urban habitats where it is planted often despite being under increasing pressure fro...

A wide variety of questions of Harmonic Analysis arise naturally in various contexts of Analytic Number Theory; in what follows we consider a number of examples of this type. The author is grateful to Dr. Ulrike Vorhauer for advice and assistance at all stages of preparation of this paper.
