Abstract India is the largest fruit and vegetable producer. Until eaten, peel stays waste. Phenolic acids, ascorbic acid, β-carotenes, flavonoids are most bioactive components of pineapples. This one secondary plant metabolites abundantly present in pineapple skins this sample, ferulic acid. Ferulic acid a low-toxic phenolic widely used diet cosmetics. extracted using different conventional non...

The coloration of tropical reef corals is mainly due to their association with photosynthetic dinoflagellates commonly known as zooxanthellae. Combining High Performance Liquid Chromatography (HPLC), spectroscopy and derivative analysis we provide a novel approach to discriminate between the Caribbean shallow-water corals Acropora cervicornis and Porites porites based on their associated pigmen...

Colorless carotenoids were accum ulated, analyzed and quantified in heterotrophicallygrow n Scenedesm us cultures treated with the bleaching herbicide norflurazon. By optical, IR and m ass spectroscopy 15-cis as well as all-trans phytofluene, 15-cis phytoenes and traces o f its all-trans isom er were identified. Furtherm ore, a phytoene epoxyde and several hydroxyphytoenes were assigned. C om p...

The distinctive color of red grapefruits is due to lycopene, an unusual carotene in citrus. It has been observed that red 'Star Ruby' (SR) grapefruits grown inside the tree canopy develop a more intense red coloration than those exposed to higher light intensities. To investigate the effect of light on SR peel pigmentation, fruit were bagged or exposed to normal photoperiodic conditions, and ch...

We have probed the absorption changes due to an externally applied electric field (Stark effect) of Photosystem I (PSI) core complexes from the cyanobacteria Synechocystis sp. PCC 6803, Synechococcus elongatus and Spirulina platensis. The results reveal that the so-called C719 chlorophylls in S. elongatus and S. platensis are characterized by very large polarizability differences between the gr...

A simple method for the simultaneous extraction and HPLC determination of provitamin A and vitamin E derivatives in vitamin supplemented (ATBC) drinks has been developed. The method allowed the complete separation of a-, b-, g-, and d-tocopherol, atocopheryl acetate, all-trans-a-carotene, all-trans-b-carotene, and the 9-cis and 13-cis isomers of b-carotene in less than 50 min. Recovery of analy...
