 Title    A New Cucurbitacin Glycoside from Kageneckia oblonga (Rosaceae)  
 Abstract    56(2) 2713888. E-mail: omunoz@abello.die.uehile.el A novel cucurbitacin glycoside has been isolated from aerial parts of Kageneckia oblonga R. et P. and shown to be 3ß-(ß-D-glucosyloxy)-16a,23a-epoxycucurbita-5,24-dien-ll-one. The structure was established by usual spectroscopic and two-dimensional (2D) NM R techniques. This compound has found to be nontoxic when tested in-vivo cell culture assays. In previous investigations we reported 23,24-dihydrocucurbitacin F and prunasine. This was the first re­ port on cucurbitacins from the genus Kageneckia (R osaceae).

 Title    Flavonoid-Aglyka als  
 Abstract    Drüsenprodukte der Moosrose (Rosa centifolica cv. muscosa) und der Japanischen Weinbeere (Rubus phoenicolasius) Flavonoid Aglycones as Glandular Products in Rosa centifolia cv. muscosa and in Rubus phoenicolasius The sticky lipophilic exudates produced by glands on inflorescences of Rosa centifolia cv. muscosa and Rubus phoenicolasius contain flavonoid aglycones. Ten differ­ ent flavonoids were identified from Rosa centifolia cv. muscosa, including several flavones with 6 ,8 -methoxy substitution. In R ubus phoenicolasius, the major fla­ vonoids are methyl ethers of quercetin.
