Inhibition of Trypanosoma cruzi by plant extracts used in Chinese medicine.
2004
In this work, we assessed the effect of extracts obtained from 17 plants used in traditional Chinese medicine. These extracts were tested in vitro with the epimastigote form of Trypanosoma cruzi, clone Bra C(15) C(2), at 27 degrees C in F-29 medium at a concentration of 100 microg/ml in axenic cultures. Allopurinol was used as reference drug. Seven plant extracts showed inhibitory activities lower than 25%. Pueraria lobata, Mahonia beaei, Dictamus dasycarpus, Kochia scoparia, Sophora flavescens and Ligustrum lucidum showed effects with inhibition values between 25% and 60%, whereas Lithospermum erythrorhizon, Saussurea lappa, Melia toosendan and Cinnamomum cassia showed the greatest inhibit…
Phylogeny and inflorescences of Berberidaceae — a morphological survey
1995
The 13 genera of Berberidaceae are investigated morphologically and cladistically in order to examine the phylogenetic relationships among the extant taxa. Cladistic analysis of 59 morphological characters using PAUP resulted in one most parsimonious tree. In the present paper main emphasis is put on inflorescence morphological features, which contributes eight characters to the current data matrix. The analysis resulted in four major clades. Nandina has a basal position, and the next clade includes Berberis and Mahonia. Ranzania is sister genus to Jeffersonia, Diphylleia/Podophyllum and Leontice/Bongardia. These all form the sister group to a clade in which Achlys is sister taxon to Epimed…
