摘要

黄杉(Endopleura uchi)是一种原产于亚马逊地区的树木,其果实在该地区很受欢迎。它富含总酚,其树皮已知具有高的卑尔根素含量,这是一种具有多种药理活性的异香豆素衍生物。然而,这种水果的营养和功能特性仍然鲜为人知。本文分析了亚马逊不同产地黄桉树果肉醇提物的营养、百分含量、矿物性质、抗氧化活性和总酚含量。同时定量测定其含量。平均纸浆得率为45.66±4.44% (w/w),水分为60.1 ~ 89.2 g 100 g-1,灰分为1.28 ~ 1.32 g 100 g-1(干基)。钙(78.2 ~ 87.1 mg 100 g-1)和钾(260.2 ~ 395 mg 100 g-1)是矿浆中含量最多的矿物质。与其他亚马逊水果相比,铝含量较高(23.7 ~ 28.7 mg 100 g-1)。果肉的高热值(325.3±20.9 Kcal 100 g-1)归因于其脂质(32 - 44.9%)和碳水化合物(48.2 - 64.1%)含量。DPPH的清除率为1.95 ~ 20.68%,与总酚含量(16.91 ~ 30.07µg GAE mg-1)密切相关。山芋素含量为180.8±55.3 mg 100 g-1。由此可见,荔枝果肉具有较高的热量和矿物质含量,同时也是卑尔根素的来源,具有潜在的营养和功能价值。

Nutritional characterization, antioxidant activity and bergenin content of the pulp of Endopleura uchi
ABSTRACT The yellow uxi (Endopleura uchi) is a tree native to the Amazon and its fruits are appreciated in the region. It is rich in total phenols and its bark is known to have high bergenin content, an isocoumarin derivative that presents several pharmacological activities. Yet the nutritional and functional properties of the fruit are still little known. We analyzed the nutritional, centesimal, and mineral properties, and the antioxidant activity and total phenol content of the alcoholic extract of yellow uxi fruit pulp from different locations in the Amazon. The bergenin content was also quantified. Average pulp yield was 45.66 ± 4.44% (w/w), with 60.1 - 89.2 g 100 g-1 of moisture and 1.28 - 1.32 g 100 g-1 of ash (dry basis). Calcium (78.2 - 87.1 mg 100 g-1) and potassium (260.2 - 395 mg 100 g-1) were the most abundant minerals in the pulp. Aluminum concentration was high compared to other Amazonian fruits (23.7 - 28.7 mg 100 g-1). The high caloric value of the pulp (325.3 ± 20.9 Kcal 100 g-1) is attributed to its lipid (32 - 44.9%) and carbohydrate (48.2 - 64.1%) content. The scavenging activity of DPPH was 1.95 - 20.68%, which was highly associated with the total phenolic content (16.91 - 30.07 µg GAE mg-1). Bergenin content was 180.8 ± 55.3 mg 100 g-1. We conclude that E. uchi pulp has high caloric and mineral content, and it is also a source of bergenin, thus this fruit has a potential nutritional and functional value.
