Pyrrolizidine alkaloids (PAs) are amino alcohols, often esterified with mono- or dicarboxylic acids, found in several plant families, including the Asteraceae. used for defence against generalist invertebrate herbivores. However, specialist herbivores that able to sequester PAs from host species derive a number of benefits these compounds. This study investigated and leaves roots southern Afric...

Botanical insecticides are increasingly attracting research attention as they offer novel modes of action that may provide effective control of pests that have already developed resistance to conventional insecticides. They potentially offer cost-effective pest control to smallholder farmers in developing countries if highly active extracts can be prepared simply from readily available plants. ...

Differences in nutrient-use efficiency have been attributed to differences in leaf habit. It has been suggested that evergreens, with their longer-lived leaves, and therefore longer nutrient retention, are more efficient than deciduous species in their use of nutrients. In tropical trees, however, leaf life span is not always a function of whole-tree deciduousness, leading to the proposal that ...

Background: The death of neurons and cerebral edema are the main consequences of stroke. However, inflammatory processes play a key role in aggravating cerebral damage following stroke. The aim of this study was to investigate the effects of Viola odorant extract (VOE) on infarct volume (IV), neurologic deficits (ND), and expression of NF-κB and VCAM-1 in the MCAO model. Method: The animals we...

Eleganoside A (1) and odoratanone A (15), a triterpenoid trisaccharide glycoside and a nortriterpenoid, together with twelve known compounds (2-13) and a mixture of cerebrosides (14) were isolated from Gelsemium elegans and Aglaia odorata. Their structures were elucidated by extensive spectroscopic and spectrometric analysis. Eleganoside A (1) features a 3-O-alpha-L-rhamnopyranosyl (1-->4)-beta...

VOLUME 77, MARCH 2006 149 Clinical Importance/Cutaneous Manifestations Ylang-ylang is an essential oil obtained by steam distillation of the fragrant flowers of the tree Cananga odorata. In Victorian times, ylang-ylang oil was mixed with coconut oil to create the famous Macassar hair oil, which was used by both men and women to enhance the hair’s luster and to promote its growth. At the turn of...
