L-jS-Pyrazolylalanine (755) and y-L-glutamyl-/8-pyrazol-L-alanine are found in the seeds of many speeies of Cucurbitaceae (65P933). It was subsequently demonstrated that free pyrazole oeeurs in watermelon seeds in eoneentrations of 280 to 410 jLg g depending on the variety (75P2512). Biosynthetic studies implieate 1,3-diaminopropane as a precursor of the pyrazole moiety of (755) (82P863). 

Pyrazol-1 -ylalanine, an isomer of histidine, was isolated from Citrullus vulgaris (watermelon) seed and its structure was confirmed by comparison with synthetic material 107). It was the major free amino acid in the dormant dry seed but was present in only trace amounts in vegetative tissue. While present in seed extracts of other members of the Cucurbitaceae, it has not been identified as occurring in members of other plant families.

Lycopene is a bright red pigment that colors several ripe fruits, vegetables, and flowers. Tomato and tomato products are the main dietary sources of this carotenoid, although it is also found in watermelons, guavas, pink grapefruits, and in small quantities in at least 40 plants. - The absorption of lycopene in the human gut is increased by heat treatment, probably because the breakdown of the plant cells makes the pigment more accessible. ... 

Carotenoids and prostate cancer — Numerous epidemiological studies including prospective cohort and case-control studies have demonstrated the protective roles of lycopene, tomatoes, and tomato-derived products on prostate cancer risk other carotenoids showed no effects. " In two studies based on correlations between plasma levels or dietary intake of various carotenoids and prostate cancer risk, lycopene appeared inversely associated with prostate cancer but no association was reported for a-carotene, P-carotene, lutein, zeaxanthin, or p-cryptoxanthin. - Nevertheless, a protective role of all these carotenoids (provided by tomatoes, pumpkin, spinach, watermelon, and citrus fruits) against prostate cancer was recently reported by Jian et al. ... 

Other common fruits are also good sources of lycopene that represents 87 to 95% of the total carotenoid content in several seeded and seedless watermelon cultivars," ° 56 to 66% in different papaya cultivars, and 24 to 58% in pink grapefruits (Table 4.2.3).

Most laboratories now employ C30 columns for separation of carotenoids from complex matrices. There are several examples for separation of carotenoids from foods such as orange, watermelon, mango, camu-camu, carrot, spinach, tomato, " sweet com, and potato. The C30 column systems shown in Table...

Watermelon cell walls, prepared as follows, were kindly provided by Dr. Niels O. Maness of the Department of Horticulture and Landscape Architecture of Oklahoma State University. Ripe watermelon mesocarp tissues were placed on ice, diced into small pieces, and then homogenized on ice in Tris-saturated phenol to give enzymically inactive watermelon cell walls [6]. The solids were collected on two layers of mira cloth and washed with water until the smell of phenol was gone. The crude cell walls were further washed with chloroform methanol (1 1, W/V) and acetone until a fluffy consistency was obtained. The acetone-washed cell wall residue was dried in an oven at 60 °C and stored in a brown bottle. 

To prepare the mild-alkali-extract, dry watermelon cell walls were suspended in a solution of 0.1 N NaOH, and allowed to react with stirring at room temperature for 15 minutes. A pH of 13, as indicated by pH paper, was kept constant during this period by addition of 0.1 N NaOH. To ensure complete reaction, the treatment was continued overnight at 4 °C. The soluble portion was separated by centrifugation at 10,000 RPM for 20 minutes in a Sorval GSA rotor. The insoluble portion was washed twice with water. The supernatants were combined and, after neutralization to pH 7.0 with acetic acid, dialyzed against distilled water and freeze dried.
