Triterpene saponins from the aerial parts of carnation (<em>Dianthus caryophyllus</em> var. <em>remontant</em>) Hort. have been studied. Three gypsogenic acid glycosides including 3-O-glucopyranoside, 3,28-O-di-glucopyranoside and 3-O-glucopyranosy1,28-0-[glucopyranosyl(1→6)glucopyranoside] have been identified by means of LSI mass spectrometry and 1H and 13C NMR. Inhibitory activities of isolated compounds against growth of the fungus <em>Trichoderma viride</em> and the growth of the roots of <em>Lepidium sativum</em> and <em>D. caryophyllus</em> seedlings were measured. None of the isolated compounds showed pronounced activity in <em>T. viride</em> test. Seedling root growth was affected severely at the presence of gypsogenic acid 3-O-glucopyranoside. Bidesmosidic form showed marginal stimulatory activity. The obtained data are discussed in relation to the activity of medicagenic acid 3-O-glucopyranoside, the compound differing just with 2-OH substitution from gypsogenic acid glycosides.

GC-MS (gas chromatography-mass spectrometry) analyses of alkaloids in the aerial parts and bulbs of Galanthus rizehensis Stern (Amaryllidaceae), collected during two different vegetation periods, was performed. Twenty three alkaloids were identified in four different alkaloid extracts. Acetylcholinesterase (AChE) inhibitory activities of the alkaloid extracts were tested. Both the highest alkaloid diversity and the most potent inhibitory activity (IC50 12.94 μg/ml) were obtained in extracts from the bulbs of G. rizehensis collected during the fruiting period.

Alkaloids of the aerial parts of P. multisectum (Maxim) Bobrov (Zygophyllaceae) growing in Mongolia have been studied by capillary Gas Chromatography-Mass Spectrometry (GC-MS) and Column Chromatography (CC). Four compounds comprising of 2-methylquinoline (1), 9-amino-2, 3,5,6,7,8-hexahydro-1H-cyclopenta [b] quinoline (2), vasicinone (3) and harmine (4) have been determined by GC-MS, while harmine (4), peganine (5), deoxypeganine (6), deoxyvasicinone (7) and harmane (8) were isolated as pure compounds by the CC. The structures of the five alkaloids 4, 5, 6, 7 and 8 were elucidated by the MS and 1H and 13C NMR analysis. The alkaloids 1, 2 and 8 were identified for the first time from this species.Mongolian Journal of Chemistry 16 (42), 2015, 48-53
