From an extract of red mamey (Pouteria sapota) β-cryptoxanthin-5,6-epoxide, β-cryptoxanthin-5',6'-epoxide, 3'-deoxycapsanthin, and cryptocapsin were isolated and characterized by UV-vis spectroscopy, electronic circular dichroism (ECD), nuclear magnetic resonance (NMR) spectroscopy, and mass spectrometry (MS). Epoxidation of β-cryptoxanthin delivered the β-(5'R,6'S)- and (5'S,6'R)-cryptoxanthin-5',6'-epoxides, which were identified by HPLC-ECD analysis. These carotenoids among others are quite common in the fruits of Central America, and as they are natural provitamins A, they should play an important role in the diet of the mostly vitamin A deficient population of this region.
从红番荔枝（Pouteria sapota）提取物中分离出β-隐黄质-5,6-环氧化物、β-隐黄质-5',6'-环氧化物、3'-脱氧辣椒红素和隐辣椒素，并通过紫外可见光谱、电子圆二色性（ECD）、核磁共振（NMR）光谱和质谱（MS）对其进行了表征。β-隐黄质的环氧化反应生成了β-(5'R,6'S)-和(5'S,6'R)-隐黄质-5',6'-环氧化物，通过HPLC-ECD分析对其进行了鉴定。这些类胡萝卜素在中美洲的水果中相当常见，由于它们是天然维生素A原，因此在该地区大部分维生素A缺乏人群的饮食中应发挥重要作用。
