Pharmacognostic and Phytochemical investigation of leaves of Pandanus odoratissimus Linn.f.
Pandanus odoratissimus Linn.f. (Syn: Pandanus fascicularis Lamk) belongs to the family Pandanacea, is a palm like small tree or shrub, which usually grow in old world tropics and few warm temperate regions. Mostly all parts are medicinally used. In the present study, histological, physical, powdered characteristics and preliminary phytochemical investigations were carried out on the leaves of P...
متن کاملCarotenoids and Photosynthesis - Regulation of Carotenoid Biosyntesis by Photoreceptors
Carotenoids are isoprenoid molecules of 40 carbons which are synthesized in a wide variety of photosynthetic (plants, algae) and non photosynthetic (some fungi and bacteria) organisms. So far, over 750 carotenoid structures are known, and these are divided into nonoxygenated molecules designated as carotenes and into oxygenated carotenoids referred to as xanthophylls. In photosynthetic organism...
متن کاملNor-Carotenoids as the Major Volatile Excretion Products of Cyanidium
Cyanidium caldarium excretes a series of nor-carotenoids. A 110 litre culture was used to isolate and determine the structure of 5 compounds: methylheptone, geranylacetone, /?-ionone, dihydrotrim ethylnaphthalene, butenylidenetrimethylcyclohexene. An algal bioassay was used to determine their effectivness on the growth of photoautotrophic organisms. The growth of Anabaena, Synechococcus, Nannoc...
متن کاملCarotenoid content of pandanus fruit cultivars and other foods of the Republic of Kiribati.
BACKGROUND Kiribati, a remote atoll island country of the Pacific, has serious problems of vitamin A deficiency (VAD). Thus, it is important to identify locally grown acceptable foods that might be promoted to alleviate this problem. Pandanus fruit (Pandanus tectorius) is a well-liked indigenous Kiribati food with many cultivars that have orange/yellow flesh, indicative of carotenoid content. F...
متن کامل1,1,6-Trimethyl-l ,2-dihydronaphthalene (TDN): A Possible Degradation Product of Lutein and beta-Carotene*
Carotenoids are unstable compounds and are easily degraded to a variety of products in the presence of oxygen and light as well as at elevated temperatures. Ohloff (1972) hypothesised that carotenoids are precursors of aromatic compounds such as C13-norisoprenoids. Recently, several C13-norisoprenoids have been identified upon liberation from their bound forms in grapes and wines (Sefton et at....
