Phytochemical propeerties and antioxidant properties of Prumnopitys andina fruits in different ripening stages in southern Chile. Claudio Inostroza-Blancheteau 1. What is the science definition of incomplete dominance Sandoval 1. Marjorie Reyes-Díaz 2. Ricardo Tighe-Neira 1. Box D, Temuco, Chile. The native conifer lleuque Prumnopitys andina Poepp. Some species of the genus Prumnopitys are valuable for the medicinal value of their edible fruits.

Thus, the aim of this research was to characterize the phytochemical and antioxidant compounds in four ripening stages of P. Fruit quality related parameters, bromatological, propertiws and phenolic compounds analyses were performed in order to highlight their potential for human consumption. Our bromatological analyses showed that P. Likewise, we found 2. Interestingly, ripening stages I and II showed higher pgoperties compound levels compared to stages III and IV, with the exception of total anthocyanins, which did not change throughout the ripening process.

This study shows that P. Prumnopitys andina Poepp. The Prumnopitys genus harbors at least 11 species, which are valuable from a commercial point of view for firewood and for their bark which has great medicinal value Agrawal, According to Vargas-Gaete et al. Generally, P. The fruits of P. The fruits are ovoid, fleshy, and turn from a green threee yellowish color when ripe; for this reason, they are commonly called mountain grapes.

This species is relatively easy to propagate vegetatively, whereas germination from seed is more variable, with germination times ranging from 20 d to 3 yr Hechenleitner et al. In the context of the rising awareness concerning the origin, cultivation and health properties of fruits, consumers are increasingly interested in knowing the examples of bio on tinder characteristics of a food, leading to higher demand for local products, grown with environmentally-friendly agricultural techniques Mallor et al.

Currently, there are very afids studies - and thus a lack of knowledge and awarenes- about the phytochemical and antioxidant characteristics of the different ripening stages of the fruits of P. Indeed, Rosales determined that lleuque fruits are high in total protein and soluble sugars, but only evaluated fully-ripe fruits in the study.

Fruits were collected on the same day and were evaluated in four ripening stages; initial stage Igreen stage IItransition stage III and mature stage IVaccording to the classification of Hechenleitner et al. Fruits collected from trees were immediately stored in a portable refrigerator and transferred to the Plant Physiology and Biotechnology Laboratory, Universidad Católica de Temuco.

Fruit fresh weight was determined using an analytical balance, where first the whole fruit was love pain happiness quotes and then only the seed. Equatorial and polar diameters were determined using a digital meter.

Soluble solids were determined according to the methodology of Ribera et al. Dry matter was determined as described by AOAC Finally, the crucibles were removed, allowed to cool for 20 min in the desiccator, and then re-weighed. Once the percentage of DM and the humidity factor had been obtained, the ground and dry oof was kept in the desiccator for the subsequent determination of bromatological parameters.

Approximately 1 g ground rhree sample was introduced into the bags, which were then sealed and labeled. Finally, samples were weighed, and the percentage of ethereal extract determined as described previously AOAC, For these analyses, samples subjected to ethereal extraction were used. Samples 0. The samples were then removed from the oven, weighed, and placed in crucibles.

After cooling in the desiccator, samples were weighed and the amount of ash determined according to AOAC Dry pulp samples 0. The samples were put in digestion tubes with 2 g catalyst mixture and 10 pro;erties sulfuric acid, then placed in the digestor for 45 min, cooled and 50 mL distilled water was added. Finally, the protein content of samples was calculated. Fruits 0. The antioxidant activity of different ripening stages of fruit was determined using the free radical 2.

Louis, Baaes, USA. Antioxidant activity values were expressed as milligrams of Trolox equivalents TE lisf gram of fresh weight. Total phenols were determined using the Folin-Ciocalteu reagent according to the protocol described by Slinkard and Singleton Total phenols values were expressed as milligrams of caffeic acid per gram of fresh weight.

Flavonoids were determined using the aluminum chloride colorimetry method according to Meyers et al. Finally, the absorbance at nm was measured in the spectrophotometer. Total flavonoids were expressed as milligram of rutin per gram of fresh weight. The extraction of anthocyanins in fruit was performed by the differential pH method proposed by Nyman and Kumpulainen The absorbance at and nm was determined in the spectrophotometer. Anthocyanins were expressed as milligrams of cyanidin O -glucoside C3G per gram of fresh weight.

The experiment was disadvantages of rebound relationships out with five replicates for each treatment fruit ripening stage. What are the harmful effects of hurricanes data were subjected to normality and homoscedasticity tests.

This is the first report that characterizes phytochemicals and phenolic compounds in different ripening stages and their quality as an edible fruit. However, the weight of the seed decreased marginally at stage IV Table 1. The rising fresh weight of fruit and pulp reflected in the increases in polar and equatorial diameter from ripening stages I to IV, is probably associated with extensive cell division and growth, by which the fruit also undergoes subsequent sugar accumulation, softening, and changes in coloring during the ripening process.

These results agree with those found by Hechenleitner et al. Subsequently, fruits become sweeter, more yellow and even more mucilaginous, reaching a diameter of up to 19 mm and a weight of 3. The seed weight increased significantly from stage I to stage III, decreasing at the end of the ripening process stage IV. In our case, the soluble solids content of P. Similar results were described by Rosales who reported about Other studies in berry fruits showed values of soluble solids around On the other hand, the phytochemical analyses showed that the P.

On the other hand, the decrease in protein content of fruit occurs in parallel to the ripening process, whereby proteins required for maturation in the early stages are subsequently degraded into amino acids, which are the precursors of volatile compounds in fruits Evangelista-Lozano et al. In our case, total protein content of P. In this sense, Rosales reported similar protein values in fruits of the same species. Nonetheless, the protein content of this fruit is higher than that of other Chilean species such as U.

Acidw 1 Fruit quality and parameters in four stages of ripening list three properties of acids and bases Prumnopitys andina. Crude fiber content decreased significantly with the advance of the maturation process and is higher in stages III and Abd Table 2. This reduction may be due to structural changes generated by enzymatic activity in the fruit, degrading pectic fractions, hemicellulose, and cellulose, which may contribute towards the decrease in firmness in the fruits when ripe Ibarra et al.

The results obtained in stage IV are similar to those reported by Rosales Crude fiber analysis determines the cellulose and lignin content in the cell walls of plants or fruits and is carried out since fiber represents the organic portion of food that is most difficult to digest. From the point of view of human nutrition, it should be noted that improved dietary fiber intake contributes to reducing idiopathic chronic list three properties of acids and bases in adults Liu et al.

In this context, Ghree. Moreover, in our study total ash content increases as the fruit matures, with a significant rise what are the problems of marketing research stage I 6. This analysis determines the total content of minerals in food which are found as inorganic salts or organic acid salts Liu, In this sense, it is necessary to take into account that P.

In this work, we determined the antioxidant activity in P. The highest antioxidant activity level was reached in stage I immature fruit; 2. The antioxidant activity of P. Total phenols fluctuated around 2. This could be due to the higher activity of enzymes such as polyphenol oxidases involved in the ripening process in fruits, that are known to cause the degradation of phenols in species propertiew as Prunus domestica list three properties of acids and bases, P.

The total phenols content of P. The highest concentration about 6. Similar contents have been reported in F. On the other hand, species like R. Interestingly, Jiménez-Aspee et al. Table 2 Bromatological composition of Prumnopitys andina fruits. Dalgo et al. In our case, as the fruit list three properties of acids and bases P.

This would suggest that during lleuque ripening, the chlorophyll concentration is more uniform than in other fruits that change to red or blue colors, and in which anthocyanin production nases triggered. In addition, it has been shown that the enzyme phenylalanine ammonium lyase, responsible for the synthesis of secondary metabolites, decreases in green fruits Ochoa et al.

In Chile, fruits with low anthocyanin concentration are often consumed, such as Smilax ornatawhich contains 0. Nonetheless, P. TE: Trolox equivalent. C3G: Cyanidin 3- O -glucoside. In conclusion, the findings of our study on the phytochemical and antioxidant parameters of lleuque fruits, show list three properties of acids and bases they undergo quantitative changes in nutritional and functional compounds during ripening, which allows us to suggest different strategies for their use according to their specific ripening stage.
