Acanthus ebracteatus Vahl. is a Thai herb that is effective in wound healing. We sought to quantitatively determine whether or not the combined application of Acanthus ebracteatus Vahl. and a collagen scaffold will increase wound closure and angiogenesis. Balb/c mice (body weight: 22-25 g) were anesthetized with sodium thiopental. The dorsal skin incision measuring 1.5 × 1.5 cm was made and the...

negatively affected by disturbance. meadow barley (Hordeum brachyantherum Nevski) (Hickman 1993). Purple needlegrass, blue wildrye, bluegrass and California melic are droughttolerant species that typically occupy well-drained upland sites. In contrast, creeping wildrye and meadow barley are less drought-tolerant and typically grow in the moist soils of seeps, streams and wetland margins (Walker...

Cissus rotundifolia (Forsk.) Vahl, a native to Africa and the Arabian Peninsula is recorded for the first time from the Peninsular India. A detailed description with illustration and relevant notes are provided for easy identification.

A new megastigmane glycoside, called pipeloside A, and a new aromadendrane type sesquiterpenoid, pipelol A, were isolated from the MeOH extract of the aerial part of Piper elongatum VAHL. along with a known megastigmane glycoside, byzantionoside B. The structures of these compounds were elucidated on the basis of spectroscopic data and chemical evidence.

Do extrato butanólico das flores de Ononis vaginalis Vahl. Symb. foram isolados dois novos glicosídeos norfenilpropanóides: 1 β-D-glicopiranosil-2-(4’hidroxifenil) (E)-eteno (trans-vaginosídeo) e 1 β-D-glicopiranosil-2-(4’hidroxifenil) (Z)-eteno (cis-vaginosídeo), e a flavanona C-glicosilada (+) 6-C-β-D-glicopiranosil (2S) naringenina (hemifolina). As estruturas destes compostos foram determina...
