Both general and specific combining abilities for creeping-rootedness of lucerne were found to be highly significant although there were substantial differences among genotypes for both parameters. These results indicate that both “additive” and “non-additive” gene effects are involved in the genetic substrate of creeping-rootedness; hence utilization of(More)
Chromatographic separation of a methanolic extract from Iris pseudopumila rhizomes led to the isolation of two new natural compounds, irilone 4'-O-[beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside] and isoscutellarein 6-C-beta-D-glucopyranoside, along with 9 isoflavonoids and 4 flavonoids. Their structures were determined on the basis of spectroscopic(More)
The methanolic extract of rhizomes of Iris pseudopumila was tested for its antibacterial and allelopathic activity. The extract was shown to have antibacterial effects. The allelopathic effect was tested against Raphanus sativus seed germination. The extract caused a decrease in the percentage of seed germination and root and epicotyl growth.
From the aerial parts of Marrubium globosum ssp. libanoticum, seven labdane diterpenoids were isolated. Three of them are new natural products [(13R)-9alpha,13alpha-epoxylabda-6beta(19),16(15)-diol dilactone (2), deacetylvitexilactone (7), marrulanic acid (8)], whereas the other four, namely, (13S)-9alpha,13alpha-epoxylabda-6beta(19),16(15)-diol dilactone(More)
A new natural labdane diterpene, marrulibanoside, was isolated from the acetonic extract of aerial parts of M. globosum Montbr. et Auch. ex Benth. ssp. libanoticum Boiss. (Lamiaceae). Its structure was determined by spectroscopic methods such as 1D and 2D NMR and mass spectrometry. Pharmacological studies have shown that the extract of M. globosum exerts(More)
