eflora of Samoa, USA: Seldom plants
The American Samoa and its small archipelago were populated by the Polynesians about 3,000 years ago. It became an unorganised US territorial area in 1900, and in fact today it is the only US territorial area just south of the equator. American Samoa indigenous autochthonous vegetation, from Whistler 1980, 1992b, 1994, 1998 and the present work, is now valued at about 343 blooming plants, 135 fern and 9 heronies.
Uncommon indigenous plants are not well known. In the Samoan Islands, the Angio sperm fauna is about a third as large as that of Fiji, which is only 1140 km to the western part, but it is greater than that of any other islands or archipelagos other than Hawaii, which has more types but fewer genus.
Botanical diversity is valued at about 540 indigenous plants (Whistler 1992a), two third of which are dicotyls. They are contained in about 283 types in 95 vegetable families. 3. Angiosperma endemicity is thought to be around 30% at the speciation stage, but only one type, Sarcopygme from the Rubiaceae genealogy, is found endemically in the area.
Michael Thomas and Art Whistler started a documentation of America's rarest plants together with the NFWF in September 2007. A total of 109 installations were recorded as a product of the overall process.
Assessment of some Samoan and Peruvian herbs using bio-synthesis of prostaglandins and rats edemaassay.
Our current programme to find new anti-inflammatory substances has assessed 58 different herb extract from 46 different medical plants used to treat inflammation diseases - 38 plants from the ancient medicines of West Samoa and eight from the Peruvian tribal medicines of Shipibo-Conibo in Amazonia.
Among the plants that have been studied, 14 showed modest to severe inhibitions, 11 of which were Samoan and three of which were from Peru. Furthermore, 12 Samoans and all eight Ecuadorian genera were examined for their inhibiting effect of ethylphenylpropiolate - in combination with rats' edema in life. Substantial activities were observed in 10 of the Samoans and all eight Ecuadorian strains.
In addition, the most prolific types were evaluated through a collection of available publications that document conventional medical applications, pharmaceutical activities and chemicals. A number of known cyclooxygenase-1 blockers have been identified to which the observable pharmacologic activities can be at least partially ascribed. Combining bibliographic chemistry and pharmacology with our own experiments can help explaining the anti-inflammatory use of these strains in IND.
