 Title      
 Abstract    Three samples of Brazilian geopropolis, collected by three indigenous bee species, were investigated by GC/MS. More than 50 compounds were identified, mainly terpenoids and phenolics. The chemical composition of propolis gathered by different bee species was dif­ ferent.

 Title    Chloroplast Autonomy in Acetyl-Coenzyme-A-Formation and Terpenoid Biosynthesis  
 Abstract    Isolated intact spinach chloroplasts were supplied with 14C-labeled C 0 2, phosphoglycerate, phos-phoenolpyruvate, acetate and mevalonate and the incorporation o f radioactivity into /?-carotene and plastoquinone-9 assayed. All applied substrates were capable of crossing the chloroplast envelope. Except phosphoenolpyruvate all radioactive precursors were incorporated into ß-carotene and also into plastoquinone-9. It is concluded that spinach chloroplasts are autonom in acetyl-coenzyme-A-formation and terpenoid biosynthesis. There is a direct carbon flow from intermediates of the Calvin-cycle via acetyl-coenzyme-A and mevalonic acid existing in the chlo­ roplast leading to the carotenoids and isoprenoid side-chains o f chlorophylls and quinones.

 Title    Antidorcas marsupialis  
 Abstract    Acyclic terpenoid compounds, aldehydes, ketones, hy­ droxy esters, and dimethyl sulphone were identified in the dorsal exudate of the antelope Antidorcas marsupialis. The novel diterpenes a-and /?-springene, found in this exudate, were synthesised from famesyl acetone.

 Title    Flavonoids and Terpenoids from the Leaf Resin of Pluchea odorata  
 Abstract    The chemical composition of the leaf resin of Pluchea odorata has been studied from material collected in Tamaulipas, Mexico. It mostly consists of triterpenes and phytosterols and an eudes-mane type sesquiterpene. Very small amounts of ten different flavonol aglycones occur, dissolved in this resin; most of them are 6-methoxy compounds. A comparison with previous results on material from El Salvador shows that the latter contains a lesser number of triterpenes and especially of flavonoids, but more sesquiterpenes, while the n-alkane composition varies only quantitatively between both populations.

 Title    Terpenoids from a Black Sea Bryozoan Conopeum seuratum  
 Abstract    In the Bryozoan Conopeum seuratum six esterified monoterpene alcohols, three free monoter-pene alcohols, three monoterpene ketones, two monoterpene aldehydes, four esters of diterpene acids, two diterpene acids and one triterpene acid were identified, most of them new for marine organisms. Some non-terpenoid compounds were identified too. Preliminary investigation on the terpenoids of the Black Sea sponge Halichondria panicea was performed and its terpenoid com­ position was compared with those of C. seuratum.

 Title    New Constituents of Essential Oil from Elsholtzia pilosa  
 Abstract    By means of GC and GCMS 31 constituents of the essential oil of Elsholtzia pilosa have been identified, 1.8-cineol representing the main component (50%). The oil composition with respect to its major constituents has been compared with other Elsholtzia species.

 Title    Diskriminîerungspheromone der sozialen Wüstenassel Hemilepistus reaumuri Discriminative Pheromones of the Social Desert Isopod Hemilepistus reaumuri  
 Abstract    A vital chemical communication can be observed in the Tunesian desert isopod Hemilepistus reaumuri. These crustaceans live in social units which are strictly closed to alien conspecifics. It was attempted to analyze the highly evolved family-specific recognition system by identifying their pheromonal compounds both from the extracts of surface washings of intact animals and from the exuvia.

 Title    Reversed Phase High Performance Liquid Chromatography of Essential Oils  
 Abstract    A reversed phase high performance liquid chromatographic procedure for the separation of essential oils is described. Applying water-acetonitrile elution systems on octyl and octadecyl-silane-bonded silica, complex mixtures o f sequiterpenes and oxygenated volatile constituents can be resolved, comparably to the quality o f gas chromatographic analysis. Photometrical detection at different wavelengths can be an important parameter in optimizing the separation of essential oil constituents. The application o f the described method is demonstrated with naturally occurring mixtures of terpenes from leaves of Cistus ladanifer.

 Title    Chemical Composition of the Wing Gland and Abdominal Hair Pencil Secretions of the Male African Sugarcane Borer, Eldana saccharina (Lepidoptera: Pyralidae)  
 Abstract    In addition to the previously identified wing gland lactone, eldanolide, and the tail brush components, vanillin and p-hydroxybenzaldehyde, several further terpenoid compounds, satu­ rated and unsaturated alcohols and acids, a thioalcohol, as well as two saturated macrocyclic lactones, were identified in the wing gland and tail brush secretions of the male African sugarcane borer Eldana saccharina (Walker). The stalk borer Eldana saccharina W alker is found in a large number of natural host plants in Africa [1]. Since 1970 it has becom e an increasingly serious pest in South African sugarcane fields [2] and it is also a recognized pest of m aize and other cereal crops in West and East African countries [3], Male moths of this insect, in common with other gallerines, have a gland at the base of each fore wing with a duct open­ ing towards the wing tip, as well as a pair of promi­ nent hair pencils on the eighth segm ent [4, 5]. These disseminating structures are assumed to be involved in pherom one com m unication in E. saccharina. The possible use of the synthetic pherom ones for monitoring and/or controlling the insect has led to considerable interest in the identification and syn­ thesis of the pherom one secreted by the male moth. The y-lactone, rra«5,-3 ,7-dim ethyl-6-octen-4-olide (eldanolide) was identified as a com ponent of the wing gland secretion [6 , 7] and several independent syntheses have been elaborated for the natural (3S, 4R) isom er [8—11]. It has been suggested [7, 12] that eldanolide acts as a long-range attractant of the fem ale. Vanillin and p-hydroxybenzaldehyde have been found in the abdominal hair pencil or tail brush secretion and were reported to act as an aphrodisiac [13]. In these studies extensive use was made of labo­ ratory methods for the evaluation of the biological Reprint requests to Prof. B. V. Burger.
