The aim of the present study was to evaluate the potential anticancer action of extracts prepared from german chamomile (Matricaria recutita L.)and pot marigold (Calendula officinalis L.) to human melanoma and epidermoid carcinoma cells. Sulforhodamine B assay was used to measure the cytotoxic activity of methanolic extracts from flowers of chamomile and marigold. The cytotoxic activity of extr...

Water scarcity is an important obstacle to the development and expansion of urban landscape in the arid and semi-arid regions of the world. Nowadays organic and artificial materials can be used to reducing water consumption without reducing the quality and quantity of urban landscape. In order to study of the effect of some mulch type on the reduce of irrigation interval on a popular seasonal p...

BACKGROUND Natural products made from plant sources have been used in a variety of cosmetic applications as a source of nutrition and as a whitening agent. The flowers of Cassia fistula L, family Fabaceae, have been used as a traditional medicine for skin diseases and wound healing and have been reported to possess anti-oxidant properties. The anti-aging effect of C. fistula flower extract on h...

Marigold oil is a product of great industrial interest thanks to its wide range medicinal and wound-healing properties. In this work, supercritical carbon dioxide was used recover marigold essential from the hexane solvent extract flowers, floral “concrete”. This starting material mixed with synthetic paraffinic waxes heighten melting point viscosity, thus, improving processability. Supercritic...

The antibacterial activity of the crude methanol extract of Woodfordia fruticosa Kurz. flower was evaluated at two different concentrations by the agar well diffusion method. The methanol extract of the flower exhibited antibacterial activity at varied levels except against Bacillus subtilis and Micrococcus flavus. The methanol extract was most active against Pseudomonas pseudoalcaligenes. The ...

The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of medicinally important plant Taraxacum officinale in its aqueous and methanol extract of root, stem and flower. Saponins, flavonoids, alkaloids, phenols were highly concentrated in the stem, root and flower, with the higher concentration of flavonoids in the flower extracts. Phenols an...

Although marigold (Tagetes patula) is known to produce allelopathic compounds toxic to plant-parasitic nematodes, suppression of Meloidogyne incognita can be inconsistent. Two greenhouse experiments were conducted to test whether marigold is more effective in suppressing Meloidogyne spp. when it is active rather than dormant. Soils infested with Meloidogyne spp. were collected and conditioned i...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

Both earthworms and symbiotic arbuscular mycorrhizal fungi (AMF) often co-occurr in ecosystems, however very little is known on their interrelationships. Here we tested to what extent earthworms (Annelida) or AMF (Glomales) separately or in combination affect the growth of the pharmaceutical plant species, pot marigold (Calendula officinalis, Asteraceae). We conducted a greenhouse experiment us...
