The stems and roots of the semiarid shrub guayule, Parthenium argentatum, contain a significant amount of natural rubber. Rubber accumulates in guayule when plants are vegetatively and reproductively dormant, complicating the relationship between growth/reproduction and product synthesis. To evaluate the factors regulating the partitioning of carbon to rubber, carbon assimilation and partitioni...

Objectives Tanacetum species are traditionally used as insecticide, and externally wound healer as well as for anti-inflammatory and antihistaminic properties. The in vivo wound-healing and anti-inflammatory potential of four Tanacetum species, Tanacetum argenteum (Lam.) Willd. subsp. argenteum (TA), Tanacetum heterotomum (Bornm.) Grierson (TH), Tanacetum densum (Lab.) Schultz Bip. subsp. sivas...

Parthenium hysterophorus L., compositae, also known as congress weed, carrot weed, star weed, reaching a height of 2 m in weeks of germination, is believed to have entered India accidentally in the mid 1950's and is now available abundantly all over the India. Leaves are traditionally used in the treatment of asthma and allergy, leavas of the plant were extracted successively using aqueous and ...

BACKGROUND Feverfew (Tanacetum parthenium L.), magnesium and coenzyme Q10 are frequently used for migraine prophylaxis. Supplementation with a fixed combination of these three agents (Antemig®, PiLeJe) was investigated in an observational study. METHODS Adult patients suffering from migraine according to the criteria of the International Headache Society were enrolled by general practitioners...

Parthenium (Parthenium hysterophorus L.) has become an invasive woody plant in recent times in many part of the world affecting the agricultural productivity. Hence we carried out to evaluate the effect of P. hysterophorus on germination and elongation of Onion (Allium cepa) and Bean (Phaseolus vulgaris). The plant extract prepared by the extractions of 1,2,4,8, and 16 gram powder in a 400ml of...

This paper describes the development of a normal-phase liquid chromatography ultraviolet-diode array detection method for the simultaneous quantification of parthenin and coronopilin in the leaves and flowers of Parthenium hysterophorous. The compounds were analyzed on a Merck Si60 silica column (5 µm, 250 × 4 mm) using an isocratic 15:85 mixture of isopropyl alcohol and hexane. The calibration...
