During the past several years, various species of Cousinia (Asteraceae) have been authenticated in Iran. However, data concerning their biological activities remain limited. The main purpose of this research was to assess potential cytotoxicity and matrix metalloproteinases (MMP) inhibitory effects of seven ethanol extracts of Cousinia using a cell line model (FibrosarcomaWEHI 164). We further ...

During the study of plant specimens in the Central herbarium Academy of Sciences of Uzbekistan Institute of the gene pool of plants and animals (TASH) one new record for the flora of Uzbekistan (Cousinia waldheimiana) was identified. This species is the fourth member of Cousinia sect. Jurineopsis collected in the Uzbek part of the Northern Alay range.

The antileishmanial and antimalarial activities of different fractions of Vincetoxicum stocksii, Carum copticum, Gentiana olivierii and Zygophyllum fabago were determined. Amongst these, V. stocksii and C. copticum showed moderate to good antimalarial activity. The ethyl acetate fractions of C. copticum and hexane fraction of V. stocksii showed 94 % and 52% inhibition of Plasmodium falciparum (...

Environmentally and technologically sulphur is a deleterious constitute in coal which makes it unsuitable for use in metallurgical industries unless the sulphur level can be reduced to the tolerable limit. Characterization of the various forms of sulphur and their associations in coal is an essential issue to find and propose a suitable desulphurization method. In this research, to evaluate sul...

Limonium stocksii (Boiss.) Kuntze (Plumbaginaceae) is a perennial, woody shrub distributed at Hawks Bay, Karachi, Pakistan. Experiments were carried out to investigate seed germination responses of L. stocksii at different salinities (0, 100, 200, 300, 400, and 500 mmol/L NaCl) and under different temperature regimes (10:20, 15:25, 20:30, and 25:35 °C), both in a 12 h dark : 12 h light photoper...

Salinity causes oxidative stress in plants by enhancing production of reactive oxygen species, so that an efficient antioxidant system, of which ascorbic acid (AsA) is a key component, is an essential requirement of tolerance. However, antioxidant responses of plants to salinity vary considerably among species. Limonium stocksii is a sub-tropical halophyte found in the coastal marshes from Guja...

The xanthippe group of species of the genus Urophora Robineau-Desvoidy, 1830 is revised and keyed. It contains seven species with a yellow area on the scutum medial to the notopleuron: Urophora bakhtiari new species (from flowerheads of Cousinia archibaldii), Urophora dirlbeki new species (from flowerheads of Onopordum acanthium), U. iani Korneyev & Merz 1998, U. impicta (Hering 1942) (= Uropho...
