Dammar-24-ene

M7cd (47) from P. ginseng and chikusetsusaponins LT5, LTg, and LN4 from the leaves of P. japonicus The latter are 3,20-glycosides of (20S)-dammar-24-ene-3/3,20-diol-12-one (48). The full structures of hovenosides D, G, and I, saponins based on jujubogenin (49) from the root bark of Hovenia dulcis, have been elucidated. [Pg.143]

S)-Dammar-24-ene-3j8,20,26-triol (48) and isofouquierol (49) have been isolated from the resin of the buds of Elaegia utilis. The stereochemistry of the latter was confirmed by hydrogenation to (20S )-dammarane-3/3,20-diol. The full paper on the X-ray analysis of alnuserol (50) has appeared. " 3-Epiocotillol II (51) has been obtained from the pollen grains of Betula platyphylla. ... [Pg.193]

Lianqiao contains triterpenoids, including oleanolic acid (0.73-2.28%), ursolic acid, betulinic acid, amyrin acetate, isobauerenyl acetate, and 20(5)-dammar-24-ene-3P,20-diol-3-acetate forsythol, forsythosides A, C, and D (1.46-1.63%), forsythin (phillyrin, phillyroside), forsythigenin (phillygenol), caf-feic acid, sterols, and rutin (imm-3). High concentrations (ca. 4%) of an antiviral and antibacterial volatile oil have also been reported in the seeds, which is probably also present in minor amounts in the dried ripe fruit. [Pg.665]
