Morphological and antioxidant characteristics of quince (Cydonia oblonga Mill.) and chinese quince fruit (Pseudocydonia sinensis Schneid.)

Abstract

Quince (Cydonia oblonga Mill.) is a fruit species, whose fruits have a high therapeutic value and therefore are used in many countries in traditional medicine. Chinese quince (Pseudocydonia sinensis Schneid.) is a lesser used species, although it is a relative of quince. The aim of the study was to evaluate some morphological characters of both kinds of fruit and antioxidant activity of morphological parts of the fruit. For these experiments, two genotypes were used from each species growing in the Arboretum Mlyňany (Slovakia). We determined the antioxidant activity of different parts by the DPPH method. In the genotypes from the evaluated species C. oblonga/P. sinensis we determined the average weight of the fruit in the fresh condition to be in the range 147.61 - 253.27 g / 197.85 - 466.38 g, the exocarp weight 28.50 - 43.89 g / 24.85 - 45.10 g, the mesocarp weight 116.36 - 204.99 g / 160.30 - 389.80 g, the seed weight 1.05 - 1.54 g / 9.22 - 17.42 g, the height of fruit 74.09 - 80.88 mm / 98.06 - 124.48 mm, average of fruit 60.11 - 81.51 mm / 62.33 - 88.64 mm. In aqueous extracts we determined antioxidant activity of the species C. oblonga / P. sinensis in dry exocarp in the range 43.52 - 67.73% / 52.76 - 82.20%, in fresh mesocarp 7.36 -14.78% / 15.30 - 23.50%, in dry mesocarp 30.92 - 41.30% / 41.68 - 50.15% and dry endocarp 55.19 - 76.44% / 91.20 - 92.72%. We determined antioxidant activity in methanolic extracts of the species C. oblonga / P. sinensis in dry exocarp in the range 93.29 - 93.32% / 91.87 - 93.25%, in fresh mesocarp 10.29 - 36.0% / 17.10 - 17.11%, in dry mesocarp 54.55 - 74.11% / 80.39 - 84.11% and in dry endocarp 95.14 - 95.39% / 94.97 - 95.62%. Results document that the fruits of both species can be practically used in the preparation of many dishes, while they can be used as raw material for pharmaceutical and cosmetic use.

Evaluation of the antioxidant activity and phenolic content of Chinese quince (Pseudocydonia sinensisSchneid.) fruit [pdf]

“…The high variability of the antioxidant activity of peel and pulp from the fruit of genotypes from Slovakia and Ukraine was confirmed by the variation coefficient (24.24%, 31.78% and 24.82%, 21.07%, respectively). Our results were in agreement with previous studies confirming the higher antioxidant activity of the peel of Pseudocydonia sinensis in comparison with the pulp (Monka et al, 2014). The higher antioxidant activity of the peel of other fruit than of the pulp has been widely reported (Ajila et al, 2007;Liu et al, 2018;Xue et al, 2009).…”

“…The variation coefficient showed a low to medium variability of the antioxidant activity of the peel and pulp of genotypes from Slovakia and Ukraine with 2.38, 5.39%, and 12.57, 11.96%, respectively. In a study by Monka et al (2014), the antiradical activity of aqueous and methanolic extracts of dry peel was 91.87-93.25%, and of dry pulp 80.39-84.11%, which showed the high antioxidant potential of different extracts. In another study, the antioxidant activity of Cydonia oblonga Mill.…”

“…ovoidea) shape (Choi et al, 2018;Klymenko et al, 2017;Mihara et al, 1987). Their fruit are very big with a height of 98.06-124.48 mm, an average diameter of 62.33-88.64 mm, and an average weight in the range of 197.85-466.38 g (Monka et al, 2014). The main volatile compounds in Chinese quince peel are expected to be (E,E)-α--farnesene, isobutyl octanoate, ethyl octanoate, isobutyl 7-octanoate, and hexyl hexanoate (Mihara et al, 1987).…”

“…In the peel, ethyl 2-methylpropanoate, ethyl (E)-2-butenoate, ethyl 2-methyl butanoate, methional, (Z)-3-hexenyl acetate, β-ionone, ethyl nonanoate, and γ-decalactone were found as the potent aroma-active compounds (Choi et al, 2018). The fresh fruit of Pseudocydonia sinensis are sour and hard, and consumed after processing into spreads, marmalades, jams, fruit jellies, candied pulp, sweetened syrups and juices, wines, liqueurs, and candies (Hamauzu et al, 2006;Klymenko et al, 2017;Monka et al, 2014).…”

Chemical Composition of Leaves of Chinese Quince (Pseudocydonia sinensis (Thouin) C.K. Schneid.)

“…Fruits of the Pseudocydonia sinensis are very fragrant, yellow edible pomes with an elliptical or ovoid shape (Mihara et al, 1987;Monka et al, 2014;Klymenko et al, 2017;Choi et al, 2018). Their fruits have a big size with a height of 98.06-124.48 mm, an average diameter of 62.33-88.64 mm, and an average weight in the range of 197.85-466.38 g (Monka et al, 2014).…”
