SUMMARY: In the present experiments, the nerve-mediated contraction of this preparation due to AITC was not inhibited by a combination of methysergide (broad-spectrum 5-HT antagonist; 0.3 micromol/l), Y 25130 (azasetron, 5-HT3 receptor antagonist; 1 micromol/l) and SB 204070 (5-HT4 receptor antagonist; 2 micromol/l) or by 5-HT receptor desensitization, that is, pretreatments that practically abolished contractions of similar size in response to exogenous 5-HT, without causing nonspecific effects. AITC also contracted longitudinal muscle-myenteric plexus preparations, an effect also fully resistant to the combination of 5-HT receptor antagonists. The pharmacology of AITC in strip preparations matched that in the whole ileum. KEY MESSAGES: It is concluded that neither endogenous 5-HT nor the gut mucosa contributes to the excitatory effect of AITC in the guinea-pig small intestine. The combination of 5-HT antagonists elaborated is suitable for studying the possible involvement of 5-HT in motor responses of the guinea-pig intestine.

Heyne ex Schult. as a wild Indian coffee species, has been rarely studied and applied in the industry nowadays. In this work, histological characters of the leaf and petiole, and polyphenolic compounds of the leaf, immature pericarp and seed were studied by LC/MS, and compared with C. arabica as a control species. The epidermis of the leaf and petiole of C. benghalensis is covered by cuticle. The leaf consists of a heterogeneous mesophyll with intercellular, palisade and spongy cells, and collateral closed bundles. These are surrounded by sclerenchyma in the petiole. Compared with Arabic coffee, the cuticle was thicker; epidermis and spongy cells smaller, and palisade cells were longer in the leaf of Bengal coffee. In the petiole, the central bundle continues into 2 small bundles in contrast to the six ones in the Arabic coffee. Five phenolic acids were identified in the leaf, immature pericarp and seed, and 4 flavonols in the leaf and pericarp. Chlorogenic acid was dominant in the non-hydrolysed seed extract, while caffeic acid in the hydrolysed extract, and isoquercitrin and rutin in the non-hydrolysed extract of the leaf. All compounds were represented at a low level in the immature pericarp. Chlorogenic, ferulic, p-coumaric and sinapic acid occur in larger amounts in the leaf and seed of C. arabica. Flavonols were documented at a higher level in the leaf of Bengal than of Arabic coffee. These preliminary results highlight the importance of study of coffee species.
