 Title    Chemical Constituents of Cor chorus capsularis and C.olitorius (Jute Plant), Part IV* Isolation of Corosolic Acid, Ursolic Acid and corosin and Correlation of Corosin with Tormentic Acid  
 Abstract    Three triterpenoids have for the first time been isolated from fresh undried jute root, ursolic acid as its acetate, corosolic acid as its acetate and indicated to be urs-2a,2/?-diol-12-en-28-oic-acid and oxo-corosin isolated as its acetate-methyl-ester, C36H54O10, m.p. 160 °C, aD-15° (c 0.435%). The 24-carboxyl in corosin-anhydro-lactone-acetate has been reduced to the methyl group and the resultant lactone on acetylation indicated to be identical with tormentic acid lactone acetate.

 Title    Investigations on Hoya Species. III. Leaf Phenolics and Latex Lipids of Hoya lacunosa Bl.  
 Abstract    Hoya lacunosa leaves contain some main C-glycosylflavonoids, which were identified as: 6-C-arabinosyl 8-C-glucosylapigenin (isoschaftoside), 6-C-glucosyl 8-C-arabinosylapigenin (schaftosi-de) and 6,8-di-C-arabinosylapigenin. In the latex triterpenols were found, often both free and in ester form, of which /?-amyrin, a-amyrin, lupeol, 24-methylenecycloartanol, obtusifoliol and cyclo-eucalenol were identified in the free alcohol fraction. The esters, forming the m ajor part o f the to­ tal lipid fraction, were solely acetates o f some of the above mentioned alcohols.

 Title    Composition of Iridals, Unusual Triterpenoids from Sword-Lilies, and the Seasonal Dependence of Their Content in Various Parts of Different Iris Species  
 Abstract    The com position o f iridals, new triterpenoids from sword-lilies, and their fatty acid esters in roots, rhizomes and leaves o f I. germ anica Linn., I. pseudacorus Linn, and two different varie­ ties o f I. pallida Lam. was determined. Quantitative analysis o f their total content in the var­ ious parts o f the plants in the course o f the year showed specific seasonal changes in rhizomes and leaves. Based on these results the possible significance o f these com pounds for the plants is discussed.

 Title    New Triterpenoid from Primula denticulata  
 Abstract    From the alcoholic extract of the plant Primula denticulata four main compounds could be isolated by column chromatography: Pri-dentigenin A, B, C and D. Several spectroscopic methods and the synthesis of several derivatives allow to determine the structure of Pridenti-genin B.

 Title    Chemical Constituents of Madhuca pasquiery  
 Abstract    Four triterpenoids, the scarce nortriterpenoid platanic acid, two flavonoids and 2,4-dihy-droxy phenylacetic acid methyl ester, hitherto unknown as a natural product, were isolated from Madhuca pasquiery. The structures were established by means of mass and NMR spectroscopy.
