摘要

Scaevola spinescens is endemic to Australia and traditionally used as a medicinal plant. While its bioactive compounds have been studied, their concentrations in different parts of the plant have not been reported. This study compared total phenolic content (TPC), flavonoids, saponins and antioxidant properties, as well as major individual phytochemical compounds in the whole root, root bark, root wood, whole stem, stem bark, stem wood, and leaf of S.?spinescens. The results showed the leaf had significantly highest concentrations of TPC followed by the root bark and stem bark (47.34, 12.24 and 10.20 mg GAE/g, respectively). Flavonoids concentrations were also significantly higher in the leaf compared to the root bark and stem bark (20.95, 6.22 and 4.19 mg CE/g, respectively). For saponins, the root bark contained significantly highest concentrations (112.58 mg EE/g). Luteolin 7-glucoside was isolated and identified in the leaf of S.?spinescens. Eight major compounds were identified with the leaf displaying the highest diversity of major compounds, and in higher concentrations, compared to the other plant constituents. As the leaf and root bark contained the highest concentrations of phytochemicals, these plant parts are recommended as starting material for future studies, to further isolate and identify the major compounds from S.?spinescens and investigate their biological properties for use in pharmaceutical and food applications.
機(jī)譯：Scaevola Spinescens是澳大利亞的地方性，傳統(tǒng)上用作藥用植物。雖然已經(jīng)研究了其生物活性化合物，但尚未報(bào)告其在植物的不同部位的濃度。該研究比較了總酚類含量（TPC），黃酮類化合物，皂苷和抗氧化劑的性質(zhì)，以及全根，根皮，根木，整個(gè)莖，莖樹皮，莖木和S. Sminescens的主要個(gè)體植物化合物。結(jié)果表明，葉子具有顯著最高的TPC濃度，然后是根樹皮和莖樹皮（分別為47.34,12.44和10.20mg / g）。與根樹皮和莖樹皮（分別為20.95,6.22和4.19mg / g）相比，黃酮類化合物濃度在葉片中也顯著較高。對于皂苷，根吠果含有明顯最高的濃度（112.58mg EE / g）。將葉黃素7-葡糖苷分離并在S.刺的葉片中鑒定。與其他植物成分相比，用展示最高多樣性的主要化合物和較高濃度的葉片鑒定出八種主要化合物。由于葉子和根吠藤含有最高濃度的植物化學(xué)物質(zhì)，因此建議這些植物部件作為未來研究的起始材料，進(jìn)一步分離和鑒定來自S.Spinescens的主要化合物并研究其在藥物和食品應(yīng)用中使用的生物學(xué)性質(zhì)。
