Study Findings
• Protoplumericin / Iridoid Bis-glucoside: Study isolated protoplumericin, 13-O-(ß-D-glucopyranosyl-p-coumaroyl)-plumieride, from the methanolic extract of A neriifolia.
• Anti-Proliferative / Cytostatic / Cytotoxic: Study evaluated the anti-proliferative effect of A schottii and A blanchetti ethanolic extracts on K562 leukemic cells. The root extract of A schottii showed to be the most active, showing dose-dependent cytostatic and cytotoxic effect.
• Anti-Viral / Anti-Rabies: Study of South American extracts and fractions showed Alamanda schottii had a selectivity index (SI) of 5.6 against rabies virus and antirabies activities.
