    In vitro and in vivo studies of the health and nutritional properties of durian (Durio zibethinus Murr.) were compared with snake fruit (Salacca edulis Reinw.) and mangosteen (Garcinia mangostana). Dietary fibers, minerals, and trace metals were comparable. Total polyphenols (mg of GAE/100 g of FW) and flavonoids (85.1 ± 6.1) were significantly higher (p < 0.05) than in snake fruit (217.1 ± 13.2 (mg of CE/100 g of FW)), durian (309.7 ± 19.3 and 61.2 ± 4.9), and mangosteen (190.3 ± 12.1 and 54.1 ± 3.8). Antioxidant activity (μM TE/100 g of FW) of durian measured by DPPH and ABTS assays (228.2 ± 13.4 and 2016.3 ± 81.1) was significantly higher (p < 0.05) than in snake fruit (110.4 ± 7.9 and 1507.5 ± 70.1) and mangosteen (79.1 ± 5.9 and 1268.6 ± 62.3). HPLC/DAD analysis of durian (μg/100 g of FW) showed that quercetin (1214.23 ± 116.7) was present at levels three times that of caffeic acid, and twice as high as p-coumaric and cinnamic acids. The correlation coefficients between the bioactive compounds of fruits and their antioxidant activities were high (R<sup>2</sup> = 0.99). Male Wistar rats (25) were divided into five dietary groups: the control group was fed the basal diet (BD); in addition to BD, the cholesterol (Chol) group was supplemented with 1% of Chol; the diets of the Chol/Durian, Chol/Snake, and Chol/Mangosteen groups were supplemanted with 5% of these fruits, respectively. It was found that diets supplemented with durian, and to a lesser degree with snake fruit and mangosteen, significantly hindered the rise in plasma lipids and the decrease in antioxidant activity. The nutritional values were comparably high. In conclusion, it could be suggested that inclusion of studied tropical fruits, especially durian, in known disease-preventing diets could be beneficial. © 2007 American Chemical Society.

    The bioactivity of Israeli Jaffa blond (Shamouti) fresh orange and Israeli Jaffa red Star Ruby (Sunrise) grapefruit juices was investigated in vitro and in vivo. The contents of bioactive compounds of these juices were determined. The influence of bioactive compounds on plasma lipids and plasma antioxidant activity in rats fed cholesterol-containing and cholesterol-free diets was assessed. Significant differences in the contents of dietary fibers were not found. The contents of total polyphenols, flavonoids, and anthocyanins in fresh orange and grapefruit juices were 962.1 ± 27.2 and 906.9 ± 27.1; 50.1 ± 3.3 and 44.8 ± 3.2; and 69.9 ± 5.6 and 68.7 ± 5.5 μg/mL, respectively. The antioxidant potential measured by the scavenging activity against nitric oxide, the β-carotene-linoleate model system (β-carotene), and the 1,1-diphenyl-2-picrylhydrazyl and 2,2′-azino-bis(3-ethyl-benzothiazoline-6-sulfonic acid) diamonium salt assays was higher in orange juice but not significantly. A high level of correlation between contents of total polyphenols and flavonoids and antioxidant potential values of both juices was found. Diets supplemented with orange and to a lesser degree with grapefruit juices improved plasma lipid metabolism only in rats fed added cholesterol. However, an increase in the plasma antioxidant activity was observed in both groups. In conclusion, fresh orange and grapefruit juices contain high quantities of bioactive compounds, which guarantee their high antioxidant potential, and the positive influence on plasma lipid metabolism and plasma antioxidant activity could make fresh orange and grapefruit juices a valuable supplement for disease-preventing diets.
