Main conclusion The leaves of Withania somnifera contained four morphologically distinct trichome types: glandular capitate, non-glandular dendritic (branched), non-glandular bicellular and non-glandular multicellular trichomes. Major phytochemical compounds present within glandular and non-glandular trichomes were alkaloids and phenolic compounds.
his article gives an overview of the potential hazards of polyphenol consumption, as reported during the round-table discussion at the 1st International Conference on Polyphenols and Health, held in Vichy, France, November 2003. Adverse effects of polyphenols have been evaluated primarily in experimental studies.
The trade in traditional medicines in South Africa is estimated to be worth R2.9 billion per year, representing 5.6% of the National Health budget. With 27 million consumers, the trade is vibrant and widespread. There are at least 133 000 people employed in the trade, with a large percentage of rural women. The plant trade is a key rural industry and business incubator.
Trichomes diversity from the study of foliar epidermal anatomy has been studied for 51 species belonging to 40 genera and 20 families. In the studied plant species, 10 different types of trichomes were observed for both glandular and eglandular types. Among these species, 38 are amphitrichomic while the remaining 13 are either epitrichomic or hypotrichomic.
The chemical constituents of some species of Euphorbia, which grow mostly in semi-desert areas in Iran and on the Alborz Mountains in the north of Tehran, have been found to include chemotaxonomically important myrsinane diterpenoids and cycloartane triterpenoids.
In this study, two Euphorbia species (i.e. terracina and paralias) were investigated for their cytotoxic and antioxidant activities.
Euphobia heterophylla is a local medicinal plant used in ethnomedicine for the treatment of
constipation, bronchitis and asthma. The aqueous decoction and the methanolic extracts were
subjected to anti-inflammatory activity using experimental animal model, in the presence of the positive
In this review we describe and discuss several approaches to selecting higher plants as candidates for drug development with the greatest possibility of success. We emphasize the role of information derived from various systems of traditional medicine (ethnomedicine) and its utility for drug discovery purposes.
Dichloromethane and 90% methanol extracts from 51 South African medicinal plants were evaluated for potential genotoxic effects using the bacterial Ames and VITOTOX† tests with and without metabolic activation.
Foliar epidermal features of 18 species of Euphorbia L. s.l. (Euphorbiaceae) are studied. While the anisocytic and anamocytic stomata are common in herbaceous members (Euphorbia subg. Chamaesyce), the paracytic type is predominant in succulent species (Euphorbia proper).
