Vegetative plants of Xanthium strumarium L. grown in long days were induced to flower by exposure to one or several 16-hour dark periods. The distribution of male and female inflorescences on the flowering shoot was described, and a scoring system was designed to assess the development of the female inflorescences. The time of movement of the floral stimulus out of the induced leaf and the timi...

The medicinal plant Xanthium strumarium L. (X. strumarium) is covered with glandular trichomes, which are the sites for synthesizing pharmacologically active terpenoids such as xanthatin. MicroRNAs (miRNAs) are a class of 21-24 nucleotide (nt) non-coding RNAs, most of which are identified as regulators of plant growth development. Identification of miRNAs involved in the biosynthesis of plant s...

Phytoextraction is gaining great attention as an alternative technique for remediation of heavy metal contaminated soils. A greenhouse study was conducted to assess heavy metal (Cd, Pb, and Zn) accumulation in three weed species viz., Avena sterils, Isatis tinctoria and Xanthium strumarium. A range of phytoavailable Cd, Pb and Zn concentrations in soils was created by applications of five diffe...

BACKGROUND The androgen comprises a group of hormones that play roles in male reproductive activity as well as personal characteristics. OBJECTIVE We investigated the androgenic activity of various herbal medicines in human prostate cancer 22Rv1 cells. MATERIALS AND METHODS Herbal extracts of Trichosanthes kirilowii (TK), Asarum sieboldii (AS), Sanguisorba officinalis (SO), and Xanthium str...

in order to investigate the environmental factors including temperature, moisture, and plant hormones on dormancy breaking of seeds of xanthium strumarium l. a number of experiments were conducted. x. strumarium seeds were dormant soon after being harvested. seed germination of cocklebur increased through a combination of cooling, temperature fluctuations following ripening. most seed germinati...

Xanthium strumarium L. is a globally successful invasive herb that has had significant negative ecological, economic and social impacts in many world regions. The present study was therefore conducted to evaluate the potential spatial distribution patterns of X. heavily invaded plant communities semiarid regions northern Pakistan. Investigations were based on data from 20 plants grown Herbarium...

Phytochemical investigation of the natural products from Xanthium strumarium led to the isolation of fourteen compounds including seven caffeoylquinic acid (CQA) derivatives. The individual compounds were screened for inhibition of α-glucosidase, protein tyrosine phosphatase 1β (PTP1β), advanced glycation end products (AGEs), and ABTS⁺ radical scavenging activity using in vitro assays. Among th...
