Diterpenoids from the aerial parts of Plectranthus ornatus.
Phytochemical investigation of a hexane extract of the aerial parts of Plectranthus ornatus yielded three new neoclerodane diterpenoids (1-3), two labdane diterpenes (4 and 5) obtained for the first time as natural products, and several previously known substances. The structures and relative stereochemistry of 1-5 were established mainly on the basis of NMR spectroscopic studies and by compari...
متن کاملAntibiotic activity of Plectranthus ornatus Codd., a Traditional Medicinal Plant.
The dichloromethane extract of Plectranthus ornatus Codd., a tradicional medicinal plant, showed antibiotic activity with minimum inhibitory concentration (MIC) values of 0.4 mg.mL-1 and 100 percent of biofilm inhibition against Staphylococcus aureus strains isolated from animals with mastitis infections. Based on these antibacterial activities, in addition to ethnopharmacological reports from ...
متن کاملVolatile organic compounds obtained by in vitro callus cultivation of Plectranthus ornatus Codd. (Lamiaceae).
Plectranthus spp (Lamiaceae) are plants of economic importance because they are sources of aromatic essential oils and are also cultivated and several species of this genus are used as folk medicines. This paper describes the effects of different concentrations of the 2,4-dichlorophenoxyacetic acid (2,4-D) and 1-naphthaleneacetic acid (NAA) on the induction of callus from nodal segments of Plec...
متن کاملIngol and ingenol diterpenes from the aerial parts of Euphorbia royleana and their antiangiogenic activities.
Ten new ingol lathyrane-type diterpenes (1-10) and two known ingenol derivatives (11 and 12) were isolated from the aerial parts of Euphorbia royleana. The structures of 1-10 were elucidated on the basis of spectroscopic methods including 2D NMR analysis, and the structure of compound 1 was confirmed by single-crystal X-ray crystallography. Antiangiogenic effects of all compounds except for 5 w...
متن کاملFlavonoids from the aerial parts of Artemisia biennis Willd
Background and objectives: The genus Artemisia contains over 250 species all over the world. A. biennis Willd is one of the species which grows wildly in Iran.
