Abstract

A total of 110 plant parts from 34 different species of medicinal and toxic plants was collected for pharmacological testing in or near the Lefaga District on the island of Upolu in Western Samoa. Voucher specimens of all species were also made. From the 110 plant parts, 211 different extracts were prepared and evaluated for antiviral, antibacterial, and anti-Ehrlich ascites tumor properties and for effects on blood pressure, heart rate, respiration, electrocardiogram, electroencephalogram, and gastric motility. Twelve extracts were effective in vitro as antibacterial agents and six inhibited Ehrlich ascites tumor growth in mice. Ninety-one extracts showed hypotensive properties, 31 for more than 30min.
