酸浆果实和花萼中类胡萝卜素含量的研究和黄色（P. pubescens L.）采用HPLC-DAD-APCI-MSn对酸浆属植物进行了鉴定。从红酸浆中共检测到69种类胡萝卜素，其中鉴定出45种。在黄色酸浆中检测到40种类胡萝卜素，鉴定出33种。研究发现，玉米黄质与各种脂肪酸的酯是红色锦灯笼中含量最丰富的类胡萝卜素，占总类胡萝卜素的51-63%，其次是β-隐黄质酯（16-24%）。黄酸浆果实中主要含有叶黄素和β-胡萝卜素等游离类胡萝卜素，总类胡萝卜素含量为19.8 ~ 21.6mg/100 g红酸浆和1.28- 1.38mg/100 g黄酸浆，是丰富的膳食类胡萝卜素来源。黄色酸浆花萼仅含有153-306 μg类胡萝卜素/g干重，而红色酸浆花萼含有显著更高的量（14.6-17.6 mg/g干重），因此可能显示出作为商业玉米黄质提取的天然来源的巨大潜力。
Carotenoid profiles of fruits and calyces of red (Physalis alkekengi L.) and yellow (P. pubescens L.) Physalis were characterized by HPLC-DAD-APCI-MSn. Altogether 69 carotenoids were detected in red Physalis, thereof, 45 were identified. In yellow Physalis, 40 carotenoids were detected and 33 were identified. Zeaxanthin esters with various fatty acids were found to be the most abundant carotenoids in red Physalis, accounting for 51-63% of total carotenoids, followed by β-cryptoxanthin esters (16-24%). In yellow Physalis, mainly free carotenoids such as lutein and β-carotene were found. Total carotenoid contents ranged between 19.8 and 21.6 mg/100 g fresh red Physalis fruits and 1.28-1.38 mg/100 g fresh yellow Physalis fruits, demonstrating that Physalis fruits are rich sources of dietary carotenoids. Yellow Physalis calyces contained only 153-306 μg carotenoids/g dry weight, while those of red Physalis contained substantially higher amounts (14.6-17.6 mg/g dry weight), thus possibly exhibiting great potential as a natural source for commercial zeaxanthin extraction.
