The chemical composition of the of grape juices produced in Korea in 1969 were analyzed and the amino acids and sugars in these juices were detected by means of paper partition chromatography. The results are summarized as follows: 1. Less sugar and amino-N and more acid were contained in Korean grape juices than those of foreign's, and tannin content was not so different as foreign's. 2. More sugar, amino-N and tannin and less acid were contained in the juices of Campbell Early obtained in Anyang district than in Taejon and Pohang districts. 3. Twenty-one amino acids detected in grape juices were distributed as following frequency. Aspartic acid, serine, glycine, asparagine, lysine, arginine, threonine, alanine butyric acid, valine, leucine, proline (in 11 varieties), glutamine, tyrosine(10), cystine(9), glutamic acid, Hydroxyproline(8), isoleucine(4), phenylalanine, unknown(3). 4. Alanine was mostly abundant in all varieties and butyric acid was next and the decreasing order were arginine, valine, leucine, proline, glutamine, threonine, etc. in the amount. 5. Number of amino acid detected in grape juices of each varieties were 20 sorts in Delaware(Anyang), 19 in Black Hamburg, and Schuyler, 18 in Campbell Early(three districts), Delaware(seedless, Taejon) and Alden, 17 in Niagara, 16 in Muscat Hamburg, and 15 in Golden Muscat. 6. Number of essential amino acids contained in Delaware(Anyang) and Black Hamburg were 6 sorts and in Campbell Early (Anyang), Niagara and Muscat Hamburg were 5 and in others 4. 7. The same number of amino acid were detected in the juices of Campbell Early obtained from three districts, but hydroxyproline was detected in that of Anyang only, while isoleucine was appeared in those of Taejon and Pohang. 8. Glucose, fructose were detected in all grape juices.

1969년도(年度) 한국산(韓國産) 포도과즙중(果汁中)에 일반성분(一般成分)을 조사(調査)하는 동시(同時)에 Paper chromatography법(法)에 의(依)하여 유리(遊離)Amino산(酸) 및 당(糖)을 동정(同定)하여 다음 결과(結果)를 얻었다. 1. 한국산(韓國産) 포도과즙(果汁)은 외국(外國)의 그것에 비(比)하여 당(糖)및Amino-N의 함량(含量)이 다소(多少) 떨어지고 산함량(酸含量)이 많았으며 Tannin의 함량(含量)에 있어서는 별차(別差)가 없었다. 2. 안양지방산(安養地方産) Campbell Early 과즙(果汁)은 대전(大田) 및 포항지방산(浦項地方産)의 것에 비(比)하여 당(糖) Amino-N 및 Tannin의함량(含量)이 다소(多少) 많았고 산(酸)의 함량(含量)이 적었다. 3. 공시(供試) 포도과즙중(果汁中)에서 동정(同定)된 21개(個)의 Amino산(酸)과 그 출현빈도(出現頻度)는 다음과 같았다. Aspartic acid, Serine, Glycine, asparagine, lysine, arginine, threonine, alanine \gamma-amino butyric acid, valine, leucine, proline (11개품종(個品種)), glutamine, tyrosine(10), cystine(9), glutamic acid, Hydroxyproline(8), isoleucine(4), phenylalanine, unknown(3) 4. Alanine의 함량(含量)이 전품종(全品種)에서 가장 많았고 다음이 butyric acid이며 Arginine, Valine, Leucine, Proline, Glutamine, Threonine의 순서(順序)로 많았다. 5. 동정(同定)된 총(總) Amino산수(酸數)는 Delaware(Anyang)(20種), Black Hamburg, Schuyler(19), Campbell Early, Delaware(seedless, Taejon), Alden(18), Niagara(17), Muscat Hamburg(16), Golden Muscat(15)의 순(順)이었다. 6. 동정(同定)된 필수(必須) Amino산수(酸數)는 Delaware(Anyang) 및 Black Hamburg가 6종(種)으로 가장 많고 Campbell Early(Anyang), Niagara, Muscat, Hamburg가 5종(種) 이었으며 그 외(外)의 품종(品種)은 4종(種) 이었다. 7. 포항(浦項), 대전(大田), 안양지방산(安養地方産) Campbell Early과즙중(果汁中)에서 同定된 Amino酸數는 18個로서 같았으나 Hydroxrproline은 전이자(前二者)에서만 나타나고 안양산(安養産)에서는 나타나지 않았으며 Iso-leucine은 이의 반대(反對)였다. 8. 과즙중(果汁中)의 유리당(遊離糖)은 Glucose와 Fructose뿐이었고Sucrose는 동정(同定)되지 않았다.
