Rediscovery of Arrabidaea chica (Bignoniaceae) and Entada polystachya var. polyphylla (Fabaceae) in Puerto Rico

Polystachyasaponin with Adjuvant Activity from Entada polystachya

A new complex triterpenoid saponin, polystachyasaponin, was isolated from leaves of Entada polystachya (L.) DC. (Leguminosae) by using chromatographic methods. Its structure was established as 15,16-dihydroxy-3-[[O-β -D-xylopyranosyl-(1→2)-O-α-L-arabinopyranosyl-(1→6)-2(acetylamino)-2-deoxy-β -D-glucopyranosyl]oxy]-(3β ,15α ,16α)-olean-12-en-28-oic acid O-D-apioβ -D-furanosyl-(1→3)-O-β -D-xylop...

Leishmanicidal, cytotoxicity and wound healing potential of Arrabidaea chica Verlot

BACKGROUND Leishmaniasis includes a wide complex of diseases that affect humans and other mammals, and can range from a mild cutaneous form to a severe visceral type. The safety of the standard treatment using pentavalent antimony is a concern due to its toxic effects. The search for alternative, effective and less toxic treatments has led to the testing of natural products. The present study a...

Chemistry and Antiviral Activity of Arrabidaea pulchra (Bignoniaceae).

The aim of the present work was to carry out a bioguided isolation of antiviral chemical constituents from an ethanol extract of leaves from Arrabidaea pulchra (Cham.) Sandwith (EEAPL) that had shown in vitro activity in a previous screening using DNA and RNA viruses. The activity of EEPAL was evaluated against the DNA viruses Human herpesvirus 1 (HSV-1) and Vaccinia virus Western Reserve (VACV...
