Chemical characterisation of Crataegus azarolus l. Fruit from 14 genotypes found in Tunisia. Bahri-Sahloul, R., Ammar, S., Grec, S., & Harzallah-Skhiri, F. Journal of Horticultural Science and Biotechnology, 2009. abstract bibtex Fruits from genotypes of 14 Crataegus were collected at the full-ripe stage at three locations in Tunisia. Fresh fruit juice was analysed for some chemical properties. The juice content [% (v/w)], pH, titratable acidity (g malic acid 100 ml -1 ), and formol index (ml NaOH 100 ml -1 juice), and the contents of total soluble solids (°Brix), total sugars [(g 100 g -1 fresh fruit weight (FW)], reducing sugars (g 100 g -1 FW), and salts (mg 100 g -1 FW), were established as: 2.0-11.9%, 3.2-4.2, 0.9-1.9, 2.8-4.4, 16.3-21.5, 5.3-17.0, 5.8-7.9, and 0.6-0.7, respectively. Fresh juice also contained vitamin C (31.4 mg ascorbic acid 100 g -1 FW, and the mineral elements; calcium (285.6-399.1 mg 100 g -1 FW), sodium (30.4-43.8 mg 100 g -1 FW), and potassium (138.5-169.2 mg 100 g -1 FW). The concentration of phenols ranged from 498.5-1,477 mg 100 g -1 FW. This study showed great variation between fruit from the 14 genotypes. Principal component analysis and hierarchical cluster analysis allowed the separation of hybrids of Crataegus species and varieties. Two groups and three sub-groups were identified. Eight genotypes were distinguished as C. azarolus var. aronia, and two others as C. azarolus var. eu-azarolus. The two genotypes of C. oxyacanthus ssp. monogyna were completely different from the other genotypes. Two genotypes were putative hybrids: C azarolus var. eu-azarolus × C. azarolus var. aronia, and C oxyacanthus ssp. monogyna × C. azarolus var. aronia. Fruit from C. oxyacanthus ssp. monogyna exhibited the highest phenol contents, and red-coloured fruit from C. azarolus var. eu-azarolus also showed high phenol content, whereas most C. azarolus var. aronia genotypes, with yellow fruit, had the highest percentage of juice and low phenol contents. Our results demonstrate the opportunity to improve and select genotypes of C. azarolus, especially those having fruit with high vitamin C and phenol contents with high anti-oxidant activities.
