(Primary and secondary development of Cyperus giganteus Vahl rhizome (Cyperaceae)). In Cyperus giganteus, like in other Monocotyledoneae, the protoderm, procambium, fundamental meristem and primary thickening meristem (PTM) are differentiated from the rhizome promeristem. The PTM produces the inner cortical parenchyma, endodermis, pericycle and amphivasal vascular bundles, which are formed by t...

The chemical composition of the essential oil obtained from the leaves of Piperovatum Vahl by hydrodistillation was analyzed by GC-MS. The main constituents found were delta-amorphene (16.5 %), cis-muurola-4(14),5-diene (14.29 %) and gamma-muurolene(13.26%). The crude extracts and isolated compounds were screened for their antimicrobial activity. Hydroalcoholic extracts of different parts of Pi...

The occurrence of arbuscular mycorrhizal (AM) fungi was surveyed along a latitudinal gradient in Arctic Canada including Banks Island (73°N), Devon Island (74°N), Ellesmere Island (76°N), and the Magnetic North Pole at Ellef Ringnes Island (78°N). At Banks Island, AM fungi were present and colonized at a high intensity in all specimens of Potentilla hookeriana Lehm. – Potentilla pulchella R.Br....

The evaluation of wound healing activity was conducted to study the effect of various extracts of Carmona retusa (Vahl) Masam. The ointment was prepared from the alcohol extract of root, stem and leaves with petroleum jelly as a base in 5% and 10% concentrations. Swiss albino mice were used for the evaluation of wound healing activity. The ointment prepared from various parts exhibited consider...
