Ridge gourd () is consumed as a vegetable after peeling off the skin which is a domestic waste. peel (LAP) was observed to be a good source of fiber (20.6 %) and minerals (7.7 %). Amino acid analysis revealed presence of the highest content of Carnosine followed by aspartic acid and aminoadipic acid. Antioxidant activity of different extracts showed that ethyl acetate extract was more potent when compared to other solvent extractions. It exhibited a significant amount of phenolic acids like p-coumaric acid (68.64 mg/100 g of dry weight) followed by gallic acid (34.98 mg/100 g of dry weight), protocatechuic acid (30.52 mg/100 g of dry weight) in free form and ferulic acid (13.04 mg/100 g of dry weight) in bound form.
丝瓜去皮后作为蔬菜食用,其皮属于生活垃圾。研究发现丝瓜皮富含纤维(20.6%)和矿物质(7.7%)。氨基酸分析显示,其中肌肽含量最高,其次是天冬氨酸和氨基己二酸。不同提取物的抗氧化活性表明,与其他溶剂提取物相比,乙酸乙酯提取物的抗氧化能力更强。它含有大量酚酸,游离形式的对香豆酸含量为68.64毫克/100克干重,其次是没食子酸(34.98毫克/100克干重)、原儿茶酸(30.52毫克/100克干重),结合形式的阿魏酸含量为13.04毫克/100克干重。
