L. belongs to the Solanaceae family and produces a spherical fruit used to treat various diseases. However, the chemical composition, nutritional characterization, and bioactive properties of the growing in the Andean region of the Atacama Desert have not been conducted so far. The results showed clear differences in the nutritional and bioactive characteristics of the fruits grown in arid environmental conditions, which were comparable to those from countries with a production tradition. The fruits studied showed a higher Ca, Cu, Mn, P, and Zn content and bioactive compounds such as flavonoids and tannins than those reported in the literature. UHPLC was performed to determine the main phenols. Gallic acid was identified as the predominant phenolic compound in this species (303.63 mg/100 g FW), of which to our knowledge no previous study has reported similar concentrations in this species. Moreover, Cape gooseberry extract has antioxidant and antimicrobial activity against Gram-positive and Gram-negative bacteria. (MIC 0.313 mg/mL and MBC 1.25 mg/mL) was the most susceptible bacterium. Meanwhile, was the most resistant bacterium (MIC and MIB 5.00 mg/mL). Furthermore, it was found to inhibit α-amylase activity with an IC value (39.28 µg/mL) similar to that of acarbose (35.74 µg/mL). These results expand the knowledge of the species cultivated in arid environmental conditions and suggest an alternative for the potential use of this fruit to manage chronic diseases such as diabetes.
L.属于茄科，其果实呈球形，可用于治疗多种疾病。然而，目前尚未对生长在阿塔卡马沙漠安第斯地区的该植物的化学成分、营养特性和生物活性进行研究。结果表明，在干旱环境条件下生长的果实，其营养和生物活性特征存在明显差异，与有生产传统的国家的果实相当。所研究的果实显示，其钙、铜、锰、磷和锌含量以及黄酮类化合物和单宁等生物活性化合物的含量均高于文献报道。采用超高效液相色谱法测定主要酚类物质。没食子酸被鉴定为该物种中的主要酚类化合物（303.63毫克/100克鲜重），据我们所知，此前没有研究报道过该物种中类似的浓度。此外，灯笼果提取物对革兰氏阳性菌和革兰氏阴性菌具有抗氧化和抗菌活性。（最低抑菌浓度为0.313毫克/毫升，最低杀菌浓度为1.25毫克/毫升）是最敏感的细菌。同时， 是最耐药的细菌（最低抑菌浓度和最低杀菌浓度为5.00毫克/毫升）。此外，还发现它能抑制α-淀粉酶活性，其半数抑制浓度值（39.28微克/毫升）与阿卡波糖（35.74微克/毫升）相似。这些结果扩展了我们对在干旱环境条件下种植的该物种的认识，并为这种果实潜在用于管理糖尿病等慢性病提供了一种选择。
