Antifungal properties of rabbit antiserum prepared by immunization are reported. The immunization was done by a chemically prepared conjugate consisting of Candida albicans (serotype A) surface mannan and human serum albumin. Addition of rabbit antiserum to d-glucose medium inoculated with C. albicans effectively inhibited its growth. Moreover, C. ...

Bacopa monnieri (L.) Wettst. was studied for shoot induction and regeneration on Murashige and Skoog (MS) medium supplemented with different plant growth regulators. Stem explants cultured on medium containing 0.1 mg/l thidiazuron (TDZ) resulted in the highest number of shoots (117 shoots/explant). Regenerated plants from medium with 0.5 mg/l TDZ c...

The variability of sorbicillin derivatives production by marine Trichoderma sp., isolated from the sponge Agelas dispar J., was studied using six different culture media to find a good medium for biomass production, particularly of trichodimerol, bislongiquinolide and bisvertinol. A simple and rapid convenient method for identification, quantificat...

Seven flavonoids were isolated from the butanol fraction of the methanolic extract of the aerial parts of Cynanchum acutum L. (Asclepiadaceae). All of which have been isolated for the first time from the genus Cynanchum. Their structures were established as quercetin 3-O-β-galacturonopyranoside (1), quercetin 7-O-β-glucopyranoside (2), tamarixtin 3...

The present study describes the cytotoxic properties of a series of 15 cyclic imides observed against different endothelial cells and K562 leukemic cells. Initially, eight structurally unrelated compounds were evaluated against cultured bone marrow endothelial cells (BMEC) and human umbilical vein endothelial cells (HUVEC). Only two imides showed c...

Calia secundiflora (Ortega) Yakovlev (Fabaceae) is considered a medicinal plant in Mexico but has scarcely been used because of the toxicity of its quinolizidine alkaloids. Several quinolizidine alkaloids have shown bactericidal, nematicidal, and fungicidal activities. The purpose of this study was to identify the alkaloids in the seeds and evaluat...

A cell suspension culture of sunflower (Helianthus annuus), a producer of immunologically active polysaccharides, was cultivated in a 5-L stirred tank bioreactor, operated in batch mode. After some changes in the internal bioreactor design a stable growth of Helianthus cells was achieved and the accumulated biomass reached 15.2 g/L (only ~5% lower ...

In electroantennographic tests isosafrol, methyl salicylate, (±)-lavandulol, geraniol, (E)-anethol, and β-ionone evoked the largest responses from antennae of female or male Oxythyrea funesta (Coleoptera: Scarabaeidae, Cetoniinae) adult beetles. In field trapping tests in Hungary the 1: 1 blend of (±)-lavandulol and 2-phenylethanol attracted signif...
