 Title    Quinolizidine Alkaloid Profiles of South American Lupins: Lupinus linearis and the Lupinus gibertianus Complex  
 Abstract    The alkaloid composition of leaves of Lupinus linearis D esr. (3 ecotypes) and L. gibertia­ nus Smith (6 ecotypes) from A rgentina and Brazil were studied by capillary gas-liquid chrom atography and GLC-mass spectrom etry (EI-M S). Both species are closely related according to morphological criteria. This view is supported by the alkaloid profiles which are very similar and share a series of new and uncom m on alkaloids. M ain alkaloids are lupanine, 13-hydroxylupanine, esters of 13-hydroxylupanine (e.g. 13-angeloyloxylupanine, 13-tigloyloxylupanine, 13-benzoyloxylupanine, 13-ci5/frans-cinnamoyloxylupanine). M inor alkaloids are: sparteine, 1 1 ,1 2 -dehydrosparteine, am m odendrine, tetrahydrorhom bifoline, angustifoline, a-isolupanine, 5,6-dehydrolupanine, 11,12-dehydrolupanine, N-formylangusti-foline, 13-ds-cinnamoyloxymultiflorine. New m inor alkaloids which have been tentatively identified by GLC-MS are 13-hydroxy-17-oxolupanine and corresponding esters (13-an-geloyloxy-17-oxolupanine, 13-tigloyloxy-17-oxolupanine, 13-benzoyloxy-17-oxolupanine, 13-cis-cinnamoyloxy-17-oxolupanine, and 13-fran.s--cinnamoyloxy-17-oxolupanine).

 Title    Species and Sex Specificity in the Odour Composition of Two Panurgine Bees (Hymenoptera, Andrenidae)  
 Abstract    From the volatile constituents of the solitary bee species Panurgus banksianus Kirby and P. calcaratus Scopuli 31 com pounds could be identified. Ih e cephalic secretion of P. banksianus is a sex specific m ulticom ponent mixture of terpenes and aliphatic carboxylic acid esters while P. cal-caratus contains m onoterpenes only. The m ajor com ponent in the D ufour's gland secretion of P. banksianus is a mac-rocyclic lactone, eicosanolide, which is absent in P. cal-caratus. In contrast, the new terpenoid ester, geranyl cit-ronellate, is present in large amounts in the D ufour's gland secretion of P. calcaratus.
