Dillenia indica

New lupanes include lup-20(29)-en-2a,3a-diol (83) from the bark of Pterocarpus santalinus62 and 3/3-hydroxylupane-13/3,28-lactone (84) from Dillenia indica,63... 

Pityrogramma triangularis (fern) (Adiantaceae), Betulaceae, Baccharis spp. (Asteraceae), Salicaceae, Prunus spp. (Rosaceae), Linaria dalmatia (Scrophulariaceae), Alpinia galanga (Zingiberaceae) glycoside in Dillenia indica (Dilleniaceae)... 

Dry ozonization of 3/3,28-diacetoxylupane afforded 19/S-hydroxy-3/3,28-diacetoxylupane (123). During the course of this work the lactone (124) was prepared. The physical properties of this lactone differ from these reported for a compound from Dillenia indica which was assigned the structure (124). This... 

An L-arabino-D-galactan, in 2% yield, has been isolated from the fruits of Dillenia indica. From the results of partial acid hydrolysis and methylation analyses, when 2,6-di-O-methyl-D-galactose, 2,3,6-tri-O-methyl-D-galactose, 2,3,4,6-tetra-(9-methyl-D-galactose, and 2,3,5-tri-O-methyl-L-arabinose residues in the molar ratio 7 3 1 8 were identified, it was concluded that the polysaccharide was a (1- 4)-j3-D-galactan that contained L-arabinofuranose residues linked at 0-3 of some of the D-galactose residues in the main chain. 

Dillenia indica (family Dilleniaceae) The common name is elephant apple. It is distributed in the humid tropical region of South and South-...
