Content of metals in the seeds of Xanthium spinosum and Xanthium italicum
Fitoterapia, 2003The quantitative analysis of metallic cations in the seeds of Xanthium spinosum L. and Xanthium italicum Moretti was performed. The differences for the two species reflect the different presence of some organic compounds having a ligand character.

The properties of the oil of Xanthium spinosum*
Journal of the American Pharmaceutical Association (Scientific ed.), 1949Some chemical and physical properties of the oil obtained from Xanthium spinosum are reported. Preliminary studies on toxicity and on blood pressure response indicate that the oil is pharmacodynamically inert.

Xanthanolides from Xanthium spinosum
Phytochemistry, 1984Abstract The aerial parts of Xanthium spinosum afforded in addition to known xanthanolides three new ones. The structures were elucidated by spectroscopic methods and by partial synthesis. Furthermore one lactone was transformed to a known derivative.

Xanthium spinosum L. - Bathurst burr
2012Bathurst burr, Xanthium spinosum (Asteraceae), is a widespread summer annual weed in rangeland, pastures and crops in eastern Australia. Possibilities for both the inundative (bioherbicide) and classical biocontrol of Bathurst burr have been explored. In the 1980s–90s, the anthracnose fungus Colletotrichum orbiculare that naturally occurs on Bathurst ...

Possible control of Xanthium spinosum by a fungus
Agriculture, Ecosystems & Environment, 1988Abstract Xanthium spinosum L. is among the world's worst weeds and is particularly important in Australia. Although susceptible to 2,4-D it often occurs near crops where the herbicide cannot be used. The fungus, Colletotrichum orbiculare (Berk. et Mont.) v.

Sesquiterpene and diterpene glycosides from Xanthium spinosum
Phytochemistry, 1996Abstract Two new sesquiterpene lactone glycosides and three new kaurene glycosides closely related to carboxyatractyloside and atractyloside, together with the 3′, 4′-didesulphated-carboxyatractyloside and 3′, 4′-didesulphated-atractyloside, were isolated from the aerial parts of Xanthium spinosum . Their structures were established by spectroscopic

Emergence and flowering in Xanthium spinosum
Agriculture, Ecosystems & Environment, 1993Abstract Xanthium spinosum , Bathurst burr or spiny clotburr is an introduced widespread annual weed in eastern Australia and several other countries. Experiments and field observations were made to contribute to understanding the species' success. Seed dormancy varied between sites and was not affected by partial fruit coat removal. Seeds in fruits

Anthracnose of Xanthium Spinosum - Quantitative Disease Assessment and Analysis.
Australasian Plant Pathology, 1988A sensitive disease assessment and analysis technique was developed for anthracnose of the weed Xanthium spinosum caused by Colletotrichum orbiculare. Time to plant death was used to discriminate between treatments. The disease rating scale reflected disease progression patterns rather than static symptoms. The mean daily rating in all treatments up to

Sclerotinia Minor - a Pathogen of Bathurst Burr (Xanthium Spinosum).
Australasian Plant Pathology, 1993A stem rot, similar to that caused by Sclerotinia minor on sunflower (Helianthus annuus), was observed on the weed, Bathurst Burr (Xanthium spinosum), in a sunflower field trial at Numurkah, in north-central Victoria. It was confirmed that the fungus causing the stem rot on the Bathurst Burr was S. minor.
