Anthralin, an anthrone derivative of chrysarobin, was introduced under the name dithranol in Great Britain decades ago. Chronic plaque-type and guttate psoriasis respond better than other variants to anthralin treatment. Topical anthralin, particularly with UV light, is long established as an effective approach to the treatment of psoriasis. ... 

Crysophanic Acid—ParietioAcid—Rheicacid—Rhein—CkHuO, —is a derivative of methylanthracene, which exists in the lichens Rarmelia parietina and Squamaria elegans, in senna, and in rhubarb, and obtainable to the extent of 80 per cent, from Goa jjOM7[Pg.453]

C16H12O5, Mr 284.27, orange needles, mp. 209-210 °C, uv ,a, 431 nm (C2H5OH). An octaketide that occurs in senna leaves (Cassia senna, Fabaceae), rhubarb roots, in chrysarobinum (see chrysarobin), lichens (Parmelia species), and fungi (Aspergillus and Penicillium species), as well as in glycosidically bound form in Cassia species.

Goa powder (Araroba powder, Bahia powder, Brazil powder, etc.), also called chrysarobin, was examined by D. S. Kemp, J. F. de Silva Lima, and Attfield. Attfield thought it was the same as the colouring matter of the rhubarb root (chrysophanic acid). Liebermann and P. Seidler showed that chrysarobin is methyldihydroxyanthranol. Chrysophanic acid, the yellow colouring matter of rhubarb, wall lichen, and other plants, was examined by... 

W. Jadassohn (1944) has already proved the possible protective effect of acanthosis against the toxic reaction of chrysarobine. A certain protective effect of acanthosis was demonstrated by de Weck and Brun (1957) against the primary toxic action of DNCB.
