摘  要：为了对香蕉果实中水溶性维生素的营养质量有更直观的了解，对不同产区（海南、云南、福建、广东、广西5个主产区）和不同种（香蕉、大蕉、皇帝蕉、粉蕉、红香蕉5个种）香蕉果实中维生素B2（VB2）、维生素B6（VB6）及叶酸3种水溶性维生素含量的差异进行比较。分析水溶性VB2、VB6及叶酸含量，比较其产地间差异和种间差异，并与其他4种热带水果进行比较。结果表明：香蕉果实中VB2、VB6、叶酸含量分别为0.058、0.338、0.010 mg/100 g，其中以VB6含量最为丰富;不同产地间香蕉果实中VB6和叶酸含量差异明显，VB2含量差异不显著;不同种香蕉果实中，以皇帝蕉果实中VB2、VB6和叶酸含量最高。与其他4种热带水果进行比较发现，香蕉果实中水溶性VB6的含量最为丰富，是芒果的2.6倍，荔枝的1.7倍。可见，香蕉果实中含有丰富的VB6，其INQ值为5.60，完全能满足人体日常推荐摄入量，可作为人体补充VB6的良好来源。

Abstract： In order to understand the nutritional quality of water-soluble vitamins in banana fruits， the differences of VB2， VB6 and folic acid in banana from different regions and varieties were compared in this paper. The water-soluble vitamin VB2， VB6 and folic acid content of five varieties， emperor banana， plantain， banana， dwarf banana， red banana from Hainan， Yunnan， Fujian， Guangdong， Guangxi was anazlyzed and compared with other four tropical fruits. The results showed that the content of VB2， VB6 and folic acid was 0.058， 0.338， 0.010 mg/100 g， respectively. Among them， the content of VB6 was the most abundant. The contents of VB2， VB6 and folic acid in emperor banana were the highest. Compared with other four tropical fruits， banana had the most abundant water-soluble vitamin VB6， which was 2.6 times as much as mango and 1.7 times as much as litchi. This study showed that bananas were rich in VB6， and the INQ value of VB6 in banana was 5.60， which fully meets the daily recommended intake of human body， and could be a good source of the supplement of VB6.

香蕉在中國有着极为悠久的栽培历史，早在2000多年前我国就已经开始种植香蕉，随着香蕉种植产业的不断发展，中国现在已成为世界第二大香蕉种植国。香蕉在我国主要分布于广西、广东、福建、云南、海南等地;在海外以中美洲居多，主要分布在南北维度30°之间的热带、亚热带地区[1-2]。研究表明，香蕉果实中有包括核黄素、吡哆类、叶酸等在内的多种水溶性维生素，其中维生素B6（VB6）的含量最为丰富，是人体补充VB6的主要食物来源[3]。水溶性维生素是维持人体正常生命活动不可或缺的营养成分，人体内水溶性维生素含量不足或过多都会造成许多疾病的产生[4]。……
