Araucaria angustifolia (Bert.) O. Kuntze (leaves) Bilobetin (3) II-7-O-methyl-robustaflavone (66) eupressuflavone (86). A Brazilian medicinal plant used for the treatment of various diseases, including dry skin, herpes disease, wounds, and sexually transmitted diseases. Bilobetin is an aetive leishmanicidal eompound. Antiviral activity antiherpes activity (Flerpes Simplex Virus type 1, HSV-1). Weniger et al., 2006[86] Freitas et al.,2009[79]. 

Araucaria angustifolia (Araucariaceae) is a Brazihan medicinal plant traditionally used for the treatment of various diseases including dry skin, wounds, shingles, and sexually transmitted diseases. The ethyl acetate (EA) and n-butanol (NB) fractions showed the best results for antiherpetic activity and further fractionation yielded 22 subfractions. Of these subfractions, 14 were active, and the most potent antiherpetic activity was obtained for the subfraction NBl-4 with a selectivity index (SI) of 57.51. Chemical analysis of NBl-4 subfractions revealed the presence of proanthocyanidins and the known biflavonoids bilobetin (l-4 -0-methylamentoflavone) (3), 11-7-0-...

All our monocentric species are in a sitnation of equilibrium and show a low ecological amplitude, which explains their restricted distribntion. Zoologists have explained the distribution of some birds and butterflies by a refuge of Quaternary forest in the Parana basin (Brown, 1982 Cracraft, 1985). The present-day distribntion of Araucaria angustifolia aadNectandra megapotamica could... 

The monocentric species (Araucaria angustifolia, Aspidospertna quebracho-bianco, Nectandra megapotamica, Schinopsis balansae and S. quebracho-colorado) are present along the axis from pole A to pole C. They are characteristic of Chacoan and Paranean poles. Because of their narrow...
