研究了热带水果加工过程中产生的果实种子、果皮和残浆的生物活性成分、体外抗氧化能力以及α -葡萄糖苷酶和α -淀粉酶的抑制活性。在针叶花、jambolan、pitanga和caja-umbu残粉中发现了花青素、槲皮素、鞣花酸（EA）和原花青素。针叶粉中酚类物质含量最高，为8839.33 mg儿茶素当量(CE)/100 g；抗坏血酸（AA）含量最高，为2748.03 mg/100 g；1,1-二苯基-2-吡啶酰肼（DPPH）抑制效果最好的是jambolan (436.76 mmol Trolox eq/g)，其次是pitanga （206.68 mmol Trolox eq/g）和针叶草（192.60 mmol Trolox eq/g），针叶草的铁还原抗氧化能力（FRAP）测定结果最高（7.87 mmol Trolox eq/g）。果粉对α -淀粉酶（IC50范围为3.40 ~ 49.5 mg CE/mL）和α -葡萄糖苷酶（IC50范围为1.15 ~ 2.37 mg CE/mL）均有抑制作用。因此，针叶树、jambolan和pitanga干燥残留物由于其丰富的生物活性化合物含量，是食品和营养保健品制造商很有前途的天然成分。
Tropical fruit residues consisting of seeds, peels and residual pulp generated as by-products of fruit processing industry were investigated for bioactive compounds, the in vitro antioxidant capacity as well as alpha-glucosidase and alpha-amylase inhibitory activities. Cyanidin, quercetin, ellagic acid (EA) and proanthocyanidins were found in acerola, jambolan, pitanga and caja-umbu residue powders. Acerola powder had the highest phenolic content (8839.33 mg catechin equivalents (CE)/100 g) and also high-ascorbic acid (AA) concentration (2748.03 mg/100 g), followed by jambolan and pitanga. The greatest 1,1-Diphenyl-2-picrylhydrazyl (DPPH) inhibition was observed for jambolan (436.76 mmol Trolox eq/g) followed by pitanga (206.68 mmol Trolox eq/g) and acerola (192.60 mmol Trolox eq/g), while acerola had the highest ferric reducing antioxidant power (FRAP) assay result (7.87 mmol Trolox eq/g). All fruit powders exhibited enzymatic inhibition against alpha-amylase (IC50 ranging from 3.40 to 49.5 mg CE/mL) and alpha-glucosidase (IC50 ranging from 1.15 to 2.37 mg CE/mL). Therefore, acerola, jambolan and pitanga dried residues are promising natural ingredients for food and nutraceutical manufacturers, due to their rich bioactive compound content.
