| Verbreitung von Iridoiden in der Gattung Verbena und einigen anderen Verbenoideae Iridoids in Verbena and Some Other Verbenoideae  | | | | Abstract
| 12 species of the genus Verbena and one Citharexylum species have been examined for iridoids. Besides the known compounds verbenaline, hastatoside, griselinoside, lamiide, ipolamiide and brasoside, two new iridoids, pulchelloside I (1) [2] and pulchelloside II (2) [3] have been isolated from Verbena species. The structures and absolute configurations of pulchelloside I and II have been determined by spectroscopical methods and some chemical reactions. Citharexylum solanaceum has been shown to contain lamiide and durantoside I. The distribution of the iridoids is in excel lent agreement with the taxonomic treatment of the genus Verbena by Schauer. The taxonomic significance of our data and some data from the literature regarding the classification of the sub family Verbenoideae is discussed. | | | |

| Accumulation of Photoassimilatory Products by Phycobiliprotein- Containing Algae with Special Reference to Cyanidium caldarium | | | | Abstract
| Representatives o f phycobiliprotein-containing algae such as Anabaena cylindrica, Anacystis ni-dulans, Gloeotrichia echinulata (Cyanophyceae), Chroomonas spec., H em iselm is rufescens, Rhodo-monas spec. (Cryptophyceae), Porphyridium cruentum, Rhodella violacea (Rhodophyceae) along with the unicellular Cyanidium caldarium (unspecified systematic status) have been investigated for their typical photoassimilatory accumulation products. While the red algal species synthesize a rather specific heteroside, 2-O-D-glycerol-ar-D-galactopyranoside (= floridoside), not encountered in the other species analyzed, blue-green algae accumulate fructose, glucose, and sucrose, while the cryptomonads accumulate only glucose and. to a lesser extent, fructose. Cyanidium synthesizes neither disaccharides, nor a heteroside, but shows rapid 14C-labelling o f fructose and glucose. These results are compared with further biochemical and structural findings and are discussed with emphasis on chemotaxonomic implications. Cyanidium caldarium is proposed as an endocya-nome consisting o f a single endocyanella providing less (apoplastidal algal?) host cell. | | | |

| Tectorigenin, a Phytoalexin of Centrosema haitiense and Other Centrosema Species | | | | Abstract
| A phytoalexin isolated from the fungus-inoculated leaflets of Centrosema haitiense, C. pubescens (3 accessions) and C. virginianum has been identified as 5,7,4'-trihydroxy-6-methoxy-isoflavone (tectorigenin). This compound is variously accompanied by other isoflavones includ ing the previously described phytoalexin, cajanin (5,2',4'-trihydroxy-7-methoxyisoflavone). Sub stantial quantities of aesculetin were obtained when C. haitiense leaves were submerged for 48 h in water or fungal spore suspensions. The taxonomic position of Centrosema within the legume tribe Phaseoleae is discussed. | | | |

| Vergleichende Untersuchungen zur Wehrchemie und Drüsenmorphologie abdominaler Abwehrdrüsen von Kurzflüglern aus dem Subtribus Philonthina (Coleoptera, Staphylinidae) Comparative Investigations on Defensive Chem istry and G land Morphology of Abdominal Defensive G lands from Rove Beetles of the Subtribe Philonthina (Coleoptera, Staphylinidae) | | | | Abstract
| Within the rove beetle subtribe Philonthina (Staphylinidae) there are found paired abdom inal defensive glands which show a bipartition and are characterized by an unique, evaginable evapo ration tissue which is described for the first time. The gland chemistry is found to be character ized by at least 27 compounds. The m ain com ponent is represented by the alkaloid actinidine, m i nor components are iridodial, three possible m onoterpenoid iridodial precursors, an octadecenole and two series o f hydrocarbons and acetates which are partly branched and unsaturated. It could be shown, that the separated gland o f the evaporation tissue, whose evagination was studied, has no different synthetic abilities as com pared with the main gland system. Chemotaxonomic results according to Hennig's principle reveal an isolated position of the rove beetle tribe Q uediini within the subfamilies X antholininae and Staphylininae. The morphologically unique defensive gland of the X antholininae may be homologized with other abdom inal glands o f the Staphylinina and Philonthina, based on the comm on presence of iridoid defensive components. | | | |

| On the Volatile Components of Heterotropa takaoi and Related Species (Aristolochiaceae) | | | | Abstract
| The volatile components of the leaves of four species and five varieties of the section Bicornes of Heterotropa were examined by gas chromatography and gas chromatograph-mass spectro-metry. The analytical results showed that the species of the section contain phenylpropanes, terpenes, and a paraffin as main components. The components have been used to construct phylogenetic trees of the section Bicornes. Despite some discrepancies, the phylogenetic tree obtained for the section seems to be relevant at the tribal revel. Among the species of the section, geographical variation of twelve localities of H. takaoi also were examined and three chemical types (myristicin, safrole, n-pentane-elemicin types) of H. takaoi are distinguished on the basis of their components. | | | |

| Surface Lipids of the Silverfish (Lepisma saccharina L.) | | | | Abstract
| Surface lipids obtained from the silverfish by short-term solvent extraction contain ali phatic hydrocarbons, monoester waxes, cholesteryl esters, triglycerides, free cholesterol, and free fatty acids. Together, cholesteryl esters and free cholesterol account for >30% of the total lipids. As found for other arthropods living in aquatic or moist environments unsaturated homo-logues predominate among the acidic constituents. The cuticular lipid composition o f silverfish resembles that of other more primitive arthro pod forms such as stoneflies and dragonflies. | | | |

| Polyphenols in Stachys and Betonica Species (Lamiaceae) Fax: 0 0 3 5 9 2 -7 0 0 -2 2 5 . E-mail: iochnp@bgcict | | | | Abstract
| Above-ground parts and roots from four Stachys species (S. germanica L., S. sylvatica L. and the Balkan endemics S. thracica Dav. and S. plumosa Griseb.) as well as o f three Betonica species (B. officinalis L. and the Balkan endemics B. bulgarica Deg. et Neic. and B. scardica Griseb.) were screened for phenols (phenylethanoid glycosides, flavonoid glycosides and the phenolic diterpene betolide). Three phenylethanoid glycosides, a flavonoid glycoside and the phenolic diterpene betolide were isolated and identified, most of them for the first time in the investigated species. The results obtained support the view that Stachys and Betonica are well separated genera. | | | |

| The alkaloid pattern of Spartium junceum has been investigated. Cytisine, N-methylcytisine, anagyrine, rhombifoline and epi-baptifoline occur as major compounds in most of the samples studied. Considerable quantitative differences were found between various parts of the plant. The alkaloid content changed strongly dependent on the seasons. Only a limited variation can be ascribed to geographical origin. | | | |
