Feverfew (Tanacetum parthenium) is a medicinal herb that has long enjoyed traditional use as a remedy for migraine headache pain. The aerial parts of Feverfew (flowers, leaves and stems) contain parthenolide (a sesquiterpene lactone) which is believed to be responsible for the plant's biological activity. Dried feverfew aerial parts should contain approximately 0.2-0.5 wt.% parthenolide and adu...

In our current study, phytochemical analysis and antibacterial activity of leaf extracts T. parthenium were assessed. Qualitative screening was carried using standard procedures quantitative for estimation total phenolic content (TPC) determined by spectrophotometric method. The accomplished disc diffusion assay, determination minimum inhibitory concentration (MIC) bactericidal (MBC) against tw...

Background & Aim: Tanacetum is a member of Asteraceae family and its twelve species such as Tanacetum walteri are endemic to Iran. In this investigation, chemical compounds and antimicrobial activity of essential oils of Tanacetum turcomanicum (Krash.) and Tanacetum walteri (C.Winkl.) were studied. Experimental: The pla...

Mechanisms that allow for the coexistence of two competing species that share a trophic level can be broadly divided into those that prevent competitive exclusion of one species within a local area, and those that allow for coexistence only at a regional level. While the presence of aphid-tending ants can change the distribution of aphids among host plants, the role of mutualistic ants has not ...

Parthenium (Parthenium hysterophorus L.), a major weed causing economic, environmental, and human and animal health problems in Australia and several countries in Asia, Africa, and the PaciÞc, has been a target for biological control in Australia since the mid-1970s. Nine species of insects and two rust fungi have been introduced as biological control agents into Australia. These include Carmen...
