Antiprotozoal activity of Senna racemosa.

Methanol extracts of leaves, roots and bark of Senna racemosa (Mill.) H.S. Irwin & Barneby (syn. Cassia racemosa Mill.) were tested for antiprotozooal activity against Giardia intestinalis and Entamoeba histolytica. All of the tested extracts showed good activity against both protozoa species. Extracts from stem bark and leaves were most active, with an IC(50) of 2.10 microg/mL for Giardia inte...

Anthraquinones from the bark of Senna macranthera.

2-acetyl physcion (2-acetyl-1,8-dihydroxy-6-methoxy-3-methyl-9,10-anthraquinone, 2), a rare anthraquinone, was isolated from Senna macranthera var. nervosa (Vogel) H.S. Irwin & Barneby (Fabaceae). The chemical structure was elucidated and all (1)H and (13)C NMR chemical shifts were assigned by NMR one- ((1)HNMR, {(1)H}-(13)CNMR, and APT-(13)CNMR) and two (COSY, NOESY, HMQC and HMBC) dimensional...

Characterization of medicinal Senna genetic resources

At 50% maturity, regenerating Senna species were characterized for morphological traits, seed reproduction, and evaluated for regeneration. Quality plants regenerated from all accessions produced 1018 to more than 21,215 total seeds. Principal component analysis revealed which traits contributed the greatest to variability among coffee senna accessions. Senna species have potential to produce p...
