INHmITION OF POTATO CYST NEMATODE HATCH BY LIGNANS FROM Bupleurum salicifolium (UNBELLIFERAE)
نویسندگان
چکیده
A series of lignans from Bupleurum salicifolium Soland (Umbelliferae) were tesled for nemalostatic activity on the cysts and freed secondstage juveniles of ¡he potalo cyst nematodes Globodera rostochiensis and G. pallida. None of Ihe six lignans lested-bursehemin, rnatairesinol, syringaresinol, Ihe novel produCI buplerol, guayarol. and a derivative, nortrachelogenin triacetale-showed nemalicidal activity in an in vilro analysis wilh second-stage juveniles, but significant differences were noled when Ihe Iignans were assayed for nematostatic activity as cysl hatching inhibitors. Bursehemin and matairesinol showed Ihe greatest activity, at concentrations of 50 ppm. This is Ihe first known instance of a natural product inhibiting Ihe hatch of Ihe nematode G. pallida. The HID (hatching inhibiting dosel of bursehemin was estimated, and some conc\usions were drawn about the structure-activity relationships of the Iignans under study. Key Words-Potato cyst nernatodes, Globodera rostochiensis, G. pallida, hatching inhibitors, lignans; Umbelliferae, Bupleurum salicifolium.

Biological activity of secondary metabolites from Bupleurum salicifolium (Umbelliferae).
Secondary metabolites from Bupleurum salicifolium were tested against viruses, Gram-positive and Gram-negative bacteria, the yeast Candida albicans, the nematodes Globodera pallida and G. rostochiensis, the insect Spodoptera littoralis and the crustacean Artemia salina. These compounds were also tested against tumoral and non-tumoral cell lines. The polyacetylene 8S-heptadeca-2(Z)-9(Z)-diene-4,...
متن کاملThe effect of mycorrhizal fungi on the hatch of potato cyst nematodes
In the presence of potato plants cv. Golden Wonder, Globodera pallida exhibited delayed in-soil hatch compared to that of G. rostochiensis, with significantly fewer G. pallida second-stage juvenile nematodes hatching in the first two weeks, though the difference disappeared after four weeks. Inoculation of potato plants with arbuscular mycorrhizal fungi eliminated this delay in G. pallida hatch...

In-vitro methods were developed to test fungi for production of metabolites affecting nematode egg hatch and mobility of second-stage juveniles. Separate assays were developed for two nematodes: root-knot nematode (Meloidogyne incognita) and soybean cyst nematode (Heterodera glycines). For egg hatch to be successfully assayed, eggs must first be surface-disinfested to avoid the confounding effe...

-Three tetrahydrofuran lignans [l-3} were obtained from the leaves of Bupleu17lm salici!olium, of which busaliol {l} and busalicifol {2} are novel. Their structures were determined by spectral and chemical methods. Also obtained in this investigation were a number of other lignans, coumarins, a polyacetylene, and a triterpenoid, all of known structure. Bupleurum salicifolium Sol!. ex Lowe (Umbe...

Globodera ellingtonae was detected in Oregon in 2008. In order to make decisions regarding the regulation of this nematode, knowledge of its biology is required. We determined the host status of a diversity of potato (Solanum tuberosum) varieties in soil-based experiments and identified hatching stimulants in in vitro hatching assays.
