Smoke from burning different kinds of vegetation or wood is often used as a cheap personal protection measure against mosquitos during the evening. To test the efficacy of smoke, a comparative field trial was conducted in the Wosera District, Papua New Guinea. Repellency of smoke from burning wild mango wood (Mangifera spp), leaves from betelnut (Areca catechu), wild ginger (Alpinia spp) and co...

Areca is a prominent commercial crop in coastal regions of Karnataka, state India. Major difficulties faced by areca growers include the shortage labor and intensive time required for collecting nuts from ground during drying process. To address above problem, an area machine modelled. For design optimization components, stress analysis on chassis, impact feeder ramp deflection conveyor belt ar...

The title compound isolated from Areca catechu L. (common name: arborinol methyl ether; a member of the arborane family) was established as 3α-methoxyarbor-9(11)-ene, C(31)H(52)O. Rings A/B/C/D assume a chair conformation, while ring E has an envelope conformation. The absolute configuration was determined to be (3R,5R,8S,10S,13R,14S,17S,18S, 21S) by analysis of Bijvoet pairs based on resonant ...

BACKGROUND Few studies have reported the association between lifestyle factors and prognosis of esophageal squamous cell carcinoma (ESCC) and among these, the effects of habitual areca nut chewing have never been examined. METHODOLOGY/PRINCIPAL FINDINGS Data from 718 pathology-proven ESCC patients recruited in a multicenter hospital-based case-control study between 2000 and 2008 in Taiwan wer...

Changes in electrolyte leakage and viability in response to dehydration stress were examined in two species of seeds that do not survive desiccation. Leakage from silver maple (Acer saccharinum L.) seeds increased markedly as seed moisture contents decreased from 45 to 35% (fresh weight basis) and germination decreased from 97 to 5%, coincidentally. Time course curves of imbibitional leakage fr...

Since antiquity, Piper betel Linn (betel vine; family Piperaceae) has been an important medicinal agent in the various traditional and folk systems of medicine in Southeast Asia countries. The leaves are the most valued plant part and in the past were routinely used as a chewing agent to prevent halitosis. The leaves are also supposed to harden the gum, conserve the teeth and to prevent indiges...
