“…The TCC in the samples was determined by BC standard calibration curve: A=mB+c; where, A = absorbance value, m = slope of the BC standard calibration curve, B = concentration of BC (µg/ml), c = y intercept of the curve. There is a limitation of the method as no prior separation process is carried out [15]. The absorbance taken at selected wavelengths is not specific for the compounds of interest.…”

This study was conducted to evaluate the total carotene content (TCC) and beta carotene (BC) in the selected underutilized tropical fruits. TCC of underutilized fruits estimated by spectrophotometric method was in the range of 1.4-19.8 mg/100 g edible portion. The TCC of these fruits decreased in the order: Jentik-jentik > Durian Nyekak 2 > Durian Nyekak 1 > Cerapu 2 > Cerapu 1 > Tampoi Kuning > Bacang 1 > Kuini > Jambu Mawar > Bacang 2 > Durian Daun > Bacang 3 > Tampoi Putih > Jambu Susu. BC contents estimated by HPLC method were highest in Jentik-jentik, followed by Cerapu 2, Durian Nyekak 2, Tampoi Kuning, Durian Nyekak 1, and Cerapu 1, which had a range of 68-92% of BC in TCC. These underutilized fruits have an acceptable amount of carotenoids that are potential antioxidant fruits.

Since the discovery of vitamin A as a fat-soluble growth factor in the early part of the century, research into carotenoids and retinoids has attracted the attention of many scientists. These two groups of compounds are still being actively studied all over the world since many gaps in knowledge exist and new frontiers are being pursued. Recent developments in studies into the possible roles of carotenoids and retinoids beyond their classical functions in vision have created a great deal of excitement in the biomedical community. This review covers a wide range of topics pertaining to these two closely related compounds. Particular emphasis is given to the functions of these compounds and their roles in human nutrition. Various aspects of vitamin A deficiency and studies on carotenoids and retinoids in cancer development and prevention are reviewed in some detail.

“…In recent years interest in carotenoid analysis has grown because the compounds seem to have antimutagenic and anti-carcinogenic properties [2]. In particular, [3-carotene is known to be important agent in the prevention of cancer; its role as a vitamin A precursor is also well known [3]. For carotenoids, HPLC is regarded as the separation technique of choice both for food and for biological matrices, as can be inferred from a recent review devoted to separation methods for the analysis of this class of compound [4].…”

SummaryThe first method for liquid chromatography-particlebeam mass spectrometry (LC-PBMS) of [~-carotene is described. It uses a reversed-phase (RP) HPLC column and methanol-dichloromethane, 90:10, as mobile phase. For comparison purposes, UV-visible detection was performed at 436 nm to determine linearity, sensitivity and precision; the absolute limit of detection of the LC-UV method was estimated to be 0.2 ng. The possible modes of ionization of [3-carotene were explored for PBMS detection; the best selectivity and sensitivity were obtained by use of electron-capture negative-ion chemical ionization (NCI). When operating in NCI mode with selected ion monitoring (SIM), the detection limit was 0.3 ng for [3-carotene, comparable with that of the UV detector.The relative standard deviation (RSD) of the LC-PBMS system was 2.6 % at the 10 ng level (n --10). For the determination of [3-carotene in real samples absolute calibration and calibration by the method of standard addition were used for both UV and PBMS detection.
