is a deciduous tree commonly known as Mediterranean hackberry or the European nettle tree. The fruit of hackberry are seldom used for nutritional purposes. The nutritional and physicochemical properties of ripe hackberry fruit from Istria (Marasi village near Vrsar, Croatia) were determined, including water, total fiber, protein, vitamin, mineral, and phenolic contents. This analysis demonstrates that the hackberry fruit is a valuable source of dietary fiber, protein, and vitamins, and of pigments such as lutein, -carotene, zeaxanthin, and tocopherols. The seasonal differences associated with the different growth stages for the element composition, total phenolic content, and phenolic profile were also determined for hackberry mesocarp and leaves. Water and ethanol extracts were prepared from mesocarp and leaves harvested at different growth stages and their phenolic profiles and antioxidant and antimicrobial activities were investigated. This study demonstrates that water and ethanol extracts of hackberry fruit and leaves collected at different growth stages contain epicatechin, gallic acid, vanillic acid, 3,4-dihydroxybenzaldehyde, delphinidin-3,5-di-O-glucoside, cyanidin-3,5-di-O-glucoside, and pelargonidin-3,5-di-O-glucoside. They also show some antimicrobial and antifungal activities. Further studies are needed to identify and define the active ingredients of these hackberry leaf ethanol extracts.
是一种落叶乔木，通常被称为地中海朴树或欧洲荨麻树。朴树的果实很少用于营养目的。对来自伊斯特拉（克罗地亚弗萨尔附近的马拉西村）的成熟朴树果实的营养和物理化学性质进行了测定，包括水分、总纤维、蛋白质、维生素、矿物质和酚类含量。该分析表明，朴树果实是膳食纤维、蛋白质和维生素以及叶黄素、β-胡萝卜素、玉米黄质和生育酚等色素的宝贵来源。还测定了朴树中果皮和叶片在不同生长阶段与元素组成、总酚含量和酚类谱相关的季节差异。从不同生长阶段收获的中果皮和叶片制备了水提取物和乙醇提取物，并研究了它们的酚类谱以及抗氧化和抗菌活性。本研究表明，在不同生长阶段采集的朴树果实和叶片的水提取物和乙醇提取物含有表儿茶素、没食子酸、香草酸、3,4-二羟基苯甲醛、飞燕草素-3,5-二-O-葡萄糖苷、矢车菊素-3,5-二-O-葡萄糖苷和天竺葵素-3,5-二-O-葡萄糖苷。它们还表现出一些抗菌和抗真菌活性。需要进一步研究来鉴定和确定这些朴树叶片乙醇提取物的活性成分。
