Euphorbiaceae is among the large flowering plant families consisting of a wide variety of vegetative forms some of which are plants of great importance. Its classification and chemistry have of late been subjects of interest possibly because of the wide variety of chemical composition of its members, many of which are poisonous but useful.
Euphorbia tirucalli L. is an important tree Euphorbia species, known for its many uses in the tropics. Endemic to tropical eastern Africa where it often grows wild, it is usually planted for boundary demarcation but also as a live fence around compounds, shrines and kraals.
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.
Sixty-seven crude ethanol extracts from 50 plants (31 families), which are used in North Cote-d’Ivoire as traditional remedies for bacte- ˆ rial diseases, were screened for in vitro activity against Gram negative (Escherichia coli and Pseudomonas aeruginosa) and Gram positive (Staphyloccocus aureus, Enterococcus faecalis, Streptococcus pyogenes and Bacillus subtilis) bacteria.
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.
