Raspberry fruit is a source of vitamin C; Vitamin C has antioxidant properties and can neutralize the negative effects of oxidative stress also are a perfect source of polyphenols, including flavonols, anthocyanins, and some experiments have indicated that organic fruits contain more bioactive compounds than conventional fruits.

The two articles of the chemical composition study use the ANOVA test, and I have use the "t studen" test, because ANOVA is a test that tells you if something with all the analyzed values is strange, but on my own I have tried to see if by the t studen test there are differences. Also there is not a web wich can make the calculation of the ANOVA actualized.

Acording to Ponder Alicja & Hallmann Ewelina (2020) they analized different chemical physical properties, and they found some cultivars of raspberry fruit to be different if they are grown on ecological conditions or in convencional conditions.

The citric acidin raspberry cultivar: in organic conditions is 1610 ± 9g/100 g and in convencional conditions is1520 ± 6g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 21 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.0001, so is considered to be extremely statistically significant, and the study pointed.

The vitamin C in raspberry cultivar: in organic conditions is 33.7 ± 1.8g/100 g and in convencional conditions is 40.5 ± 2.6g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 21 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.0001, so is considered to be extremely statistically significant, and the study pointed.

The caffeic in raspberry cultivar: in organic conditions is 0.24 ± 0.11g/100 g and in convencional conditions is 0.21 ± 0.11g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 21 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.3249, so is considered to be not statistically significant, as the study "p".

The ferulic in raspberry cultivar: in organic conditions is 0.20 ± 0.09g/100 g and in convencional conditions is 0.34 ± 0.18g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 21 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.0002, so is considered to be statistically significant, the study is not correct, the author have made a mistake.

The Ellagic in raspberry cultivar: in organic conditions is 57.1 ± 3.5g/100 g and in convencional conditions is 38.2 ± 2.4g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 21 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: less than 0.0001 , so is considered to be extremely statistically significant, study is not correct, the author have made a mistake.

Acording to Alicja et al, (2019) they analized different chemical physical properties, and they found some cultivars of raspberry fruit to be different if they are grown on ecological conditions or in convencional conditions.

The quercetin in raspberry cultivar: in organic conditions is 0.46 ± 0.16Ag/100 g and in convencional conditions is 0.32 ± 0.16g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 20 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.0028, so is considered to be not statistically significant, as the study "p".

The kaempferol in raspberry cultivar: in organic conditions is 1.82 ± 0.49g/100 g and in convencional conditions is 1.35 ± 0.17g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 20 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: less than 0.0001 , so is considered to be extremely statistically significant, study is not correct, the author have made a mistake.

The gallic in raspberry cultivar: in organic conditions is 0.30 ± 0.56g/100 g and in convencional conditions is 0.18 ± 0.11g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 36(eco) and n= 20 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: 0.3491 , so is considered to be not statistically significant, as the study said.

The myrycetin in raspberry cultivar: in organic conditions is 3.47 ± 0.05g/100 g and in convencional conditions is 4.16 ± 0.09g/100 g. The authors "p < 0,05", if I calculate the t student test knowing n= 18(eco) and n= 8 (convenvional), with the next websit Graphad Student t Test Online The calculate "p" is: less than 0.0001, so is considered to be extremely statistically significant, study is not correct, the author have made a mistake.
