Haematomma ventosum

Two naphthofurandiones, namely the 2-ethyl derivative of 84 and 89, were isolated from heartwood of P. peroba, in addition to lapachol, lapachone, and benzochromendiones (68N38). Related quinones 90 (mixtures of enantiomers) were isolated from wood of Rademachera sinica (81JCS(P1)2764). Helicquinone (91) was isolated from Helicteres angustifolia (87P578) and haemoventosin (92), a colored compound, was isolated from a lichen, Haematomma ventosum (71ACS483). [Pg.57]

Figure 9 In situ analysis of the pigment haemoventosin in the apothecia of a microlichen Haematomma ventosum using FT-LMMS. The structural assignment of the anions of major diagnostic interest is based on the high accuracy m/z data in Table 1.

Haemoventosin (202), isolated from Haematomma ventosum (34), was assigned this structure on the basis of the spectroscopic evidence. The position of the ester group, which could not be assigned by spectrometric means, was deduced from biosynthetic considerations. [Pg.142]

Bruun and Motzfeld (35) isolated the novel peroxyergosteryl divari-catinate (525) from the lichen Haematomma ventosum. This product is the only known example of a steryl ester of an aromatic polyketide derived acid. The depside divaricatic acid (234) also present in this lichen contains the same A-ring component and it is possible that the ester formation in both of these metabolites is effected by the same enzyme. [Pg.214]
