Phlebic acid

A further hopane constituent of the lichen Peltigera aphthosa is phlebic acid B (125). " Woodwardic acid, from Woodwardia orientalis, is 3jff-hydroxy-21y5H-hop-22(29)-ene-23-carboxylic acid (126). Mollugogenol E (127), from Mollugo hirta, has been correlated with niollugogenol A. [Pg.176]

Phlebic acid A, which co-occurs in the lichen Peltigera aphthosa with 15a-acetoxy-22-hydroxyhopane (dustanin monoacetate) is 28-acetoxy-22-hydroxy-hopan-23-oic acid (216). Mollugogenol B and C, new saponins from Mollugo... [Pg.195]

Leucotylic acid (98), phlebic acid A (99), and phlebic acid B (100) are hopane derivatives with a 23-carboxylic acid from Parmelia leucotyliza yl., P. entotheiochroa Hue, and Peltigera aphthosa (L.) Willd. Diacetyl pyxinol (101), known from Pyxine endochrysina yX., possesses adammaran skeleton from X-ray analysis of 3/3, 12/3-di-/ -bromobenzoyl pyxinol. [Pg.515]

The stucture of phlebic acid D was determined by X-ray crystallography as 7p-acetoxy-22-hydroxyhopan-27-oic acid (581). Its conversion to phlebic acid C (see Scheme 181) established the structure of the latter as 22-hydroxyhopan-27-oic acid (580) 24). [Pg.206]
