(Moench), Rudbeckia fulgida var. sullivantii, Boyton et Beadle, and Rudbeckia speciosa Wenderoth show immunomodulating activity. The mice were treated in vivo for 5 days and the activity was tested for and observed on day 7. An immunostimulatory effect was observed on the phagocytic, metabolic and bactericidal activities of peritoneal macrophages. The ethanolic extracts of both Echinacea plants also increased the total weight of the spleens as compared to the effect of the Rudbeckia plants and the control group which received saline. €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€ Bukovsky M Vaverkova S Kostalova D Magnusova R [Immunomodulating activity of ethanol-water extracts of the roots of Echinacea gloriosa L., Echinacea angustifolia DC. and Rudbeckia speciosa Wenderoth tested on the immune system in C57BL6 inbred mice] Imunomodulacna aktivita etanolovo-vodnych extraktov z korennov Echinacea gloriosa L., Echinacea angustifolia DC. a Rudbeckia speciosa Wenderoth testovana na imunitnom systeme inbrednych mysi C57BL6.

The most marked immunostimulatory effect was observed on the lysosomal and peroxidal activity of peritoneal macrophages, and splenic cells after in vivo treatment with the ethanolic extract of the roots of R. speciosa Wenderoth. €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€ *****PLANTA MEDICA***** Constabel CP Towers GH The complex nature of the mechanism of toxicity of antibiotic dithiacyclohexadiene polyines (thiarubrines) from the asteraceae. In: Planta Med (1989 Feb) 55(1):35-7 ISSN: 0032-0943 Thiarubrine A, a dithiacyclohexadiene polyine from the roots of Chaenactis douglasii, and a related dithiacyclohexadiene from Rudbeckia hirta exhibit strong light-independent antibacterial and antifungal activity. This activity is enhanced by exposure to visible light. Visible light also converts the compounds to the corresponding thiophenes. These are antibiotic only when irradiated with UV-A. Dithiacyclohexadienes are the first polyines to exhibit such complex mechanisms of toxicity towards microorganisms.
