Persea americana fruit and leaves had been known in folk medicine for their anti-diabetic prowess. Therefore, this study sought to investigate the inhibitory effect of phenolic extract from avocado pear (Persea americana) leaves and fruits on some key enzymes linked to type 2 diabetes (α-amylase and α-glucosidase); and sodium nitroprusside (SNP) induced lipid peroxidation in rats' pancreas in v...

The research work focused on the effect of aqueous extract of the seed of Persea americana (Avocado) on the cholesterol, triglycerides, low density lipoproteins levels in the blood of rabbits. A total of thirty rabbits were used of ten in each of groups A, B and C. Group A served as control. The test groups (B and C) were fed ad libitum with starter finish before and after administration of the...

D of the sugarcane and pineapple industries in Hawai‘i has resulted in an increased shift toward diversified agriculture. According to the Hawai‘i Agriculture Statistics Services’ 2005 summary of diversified agriculture sales in Hawai‘i, tropical fruits, excluding pineapple, were ranked seventh, comprising 5.9 percent of total diversified sales. Among the different tropical fruits, avocado make...

Avocados are grown in many countries of the world and are consumed principally as fresh fruits. In marketing fresh avocados, imperfect and odd-sized fruits are usually rejected. In addition, the fruits selected require special handling because of their highly perishable nature. Therefore, the development of new avocado products and of improved methods of preservation are of interest to avocado ...

The aqueous extract of Persea americana leaves produced a dose-dependent inhibition of both phases of formalin pain test in mice, a reduction in mouse writhing induced by acetic acid and an elevation of pain threshold in the hot plate test in mice. The extract also produced a dose-dependent inhibition of carrageenan-induced rat paw oedema. The results obtained indicate that the extract possesse...

The present study investigated the vasorelaxant action of the aqueous leaves extract of Persea americana on isolated rat aorta. The results showed that the extract produced significant vasorelaxation and that the effect is dependent on the synthesis or release of endothelium-derived relaxing factors (EDRFs) as well as the release of prostanoid. The extract also reduced vasoconstriction probably...

Persea schiedeana, a close relative of avocado (Persea americana), is an important part of agroforestry systems and diets in parts of Mesoamerica, particularly in the coffee growing areas of southeastern Mexico and Guatemala, where it is known as chinene, coyo, and yas. Little research attention has been given to this species, other than as a rootstock for avocado. Research carried out in six v...

In an effort to establish the relative as well as absolute configuration of the trypanocidally active natural nonadec-6-en-1,2,4-triol isolated from Persea americana, the (2S,4R), (2S,4S), and (2R,4R) isomers were synthesized. The stereogenic centers taken from enantiopure chiral epoxy building blocks derived from inexpensive and readily available D-glucolactone. The (2R,4R) isomer gave (1)H an...

The redbay ambrosia beetle, Xyleborus glabratus Eichhoff (Coleoptera: Curculionidae: Scolytinae), and its fungal symbiont, Raffaelea sp., are new introductions to the southeastern United States responsible for the wilt of mature redbay, Persea borbonia (L.) Spreng., trees. In 2006 and 2007, we investigated the seasonal flight activity of X. glabratus, its host associations, and population level...

—Histura perseavora Brown, new species, from Guatemala, is described and illustrated. It is compared with Histura curvata (Meyrick) from Brazil and Histurodes costaricana Razowski from Costa Rica. All specimens of H. perseavora were reared from either fruit, fruit pedicels, or young green branches of avocados (Persea americana Mill.; Lauraceae) during efforts to identify lepidopteran pests of t...
