The European gooseberry () is still an understudied crop with limited data available on its biochemical profile and postharvest life. A variety of polyphenols were detected in the skin and flesh of 20 gooseberry cvs, representing mainly flavonol glycosides, anthocyanins and flavan-3-ols. In contrast, gooseberry seeds were for the first time characterised by the presence of considerable amounts of hydroxycinnamic acid glycosides tentatively identified by UPLC-QToF/MS. All cvs examined represented a good source of vitamin C while being low in sugar. Furthermore, the postharvest stability of bioactives was explored by supplementation of exogenous ethylene in air at 5 °C. Results suggest a low sensitivity of gooseberries to ethylene. The overall quality of gooseberries remained stable over two weeks, showing potential for extended bioactive life.
欧洲醋栗仍是一种研究不足的作物，关于其生化特性和采后寿命的数据有限。在20个醋栗品种的果皮和果肉中检测到了多种多酚类物质，主要包括黄酮醇苷、花青素和黄烷-3-醇。相比之下，醋栗种子首次被鉴定出含有大量通过超高效液相色谱-四极杆飞行时间质谱（UPLC-QToF/MS）初步鉴定的羟基肉桂酸苷。所有检测的品种都是维生素C的良好来源，同时含糖量较低。此外，通过在5°C的空气中补充外源乙烯来探索生物活性物质的采后稳定性。结果表明醋栗对乙烯的敏感性较低。醋栗的整体品质在两周内保持稳定，显示出延长生物活性寿命的潜力。
