Freshwater macroalgae possess a number of important secondary metabolites. They are an unexplored source of medicinal compounds. In this study, three freshwater macroalgae—Chara vulgaris, Cladophora glomerata and Spirogyra crassa—were collected from the river Swat and the river Kabul in the Charsadda district of Khyber Pakhtunkhwa, Pakistan. To assess the role of freshwater macroalgae in agriculture, various experiments were performed on their extracts. Methanolic extract of the three macroalgae were first analyzed through gas chromatography–mass spectrometry (GC–MS) for the presence of important medicinal secondary metabolites. The methanol based macroalgae extracts were tested for antibacterial, insecticidal, cytotoxic and phytotoxic activities. Initially, the algae were dried, crushed and treated with methanol for the extraction of secondary metabolites. The GC–MS results contained several important long chain fatty acids and other related long-chain hydrocarbons, such as alkanes and alkenes. Several benzene derivatives were also detected during the course of the investigation. Several of these compounds have established roles in the treatment of human ailments and can be supplied to farm animals. For example, phenylephrine is a decongestant, dilates pupils, increases blood pressure and helps in relieving hemorrhoids. Hexahydropseudoionone has uses in perfumes and other cosmetics. Several essential oils were also detected in the methanolic extract of the three macroalgae that can be utilized in various industrial products. Bioassays showed that these algal extracts—especially the Spirogyra sp. extract—contain moderate to maximum bioactivity. Macroalgae possess important secondary metabolites with medicinal properties. These secondary metabolites can be used as biopesticides, plant growth enhancers, and remedies for various diseases in farm animals and for the control of weeds. They can be further explored for isolation and purification of useful biochemical compounds.

研究选定淡水大型藻类的重要生化化合物及其在农业中的作用
淡水大型藻类拥有许多重要的次生代谢物。它们是未开发的药用化合物来源。在这项研究中,从巴基斯坦开伯尔普赫图赫瓦省 Charsadda 区的斯瓦特河和喀布尔河采集了三种淡水大型藻类——Chara vulgaris、Cladophora glomerata 和 Spirogyra crassa。为了评估淡水大型藻类在农业中的作用,对其提取物进行了各种实验。首先通过气相色谱-质谱 (GC-MS) 分析三种大型藻类的甲醇提取物中是否存在重要的药用次生代谢物。测试了基于甲醇的大型藻类提取物的抗菌、杀虫、细胞毒性和植物毒性活性。最初,藻类被干燥,粉碎并用甲醇处理用于提取次级代谢物。GC-MS 结果包含几种重要的长链脂肪酸和其他相关的长链烃,例如烷烃和烯烃。在调查过程中还检测到了几种苯衍生物。其中一些化合物已在治疗人类疾病中发挥作用,并可提供给农场动物。例如,去氧肾上腺素是一种减充血剂,可以扩张瞳孔、增加血压并有助于缓解痔疮。六氢假紫罗兰酮可用于香水和其他化妆品。在可用于各种工业产品的三种大型藻类的甲醇提取物中还检测到几种精油。生物测定表明,这些藻类提取物——尤其是 Spirogyra sp。提取物——含有中等至最大的生物活性。大型藻类具有重要的具有药用特性的次生代谢物。这些次生代谢物可用作生物杀虫剂、植物生长促进剂和治疗农场动物各种疾病和控制杂草的药物。可以进一步探索它们以分离和纯化有用的生化化合物。
