Abstract Bayhops (Ipomoea pes-caprae (L.) R. Br.) is a kind of creeping herb growing in the coastal areas which can produce specific metabolites that are beneficial to humans. A study on the chlorophyll contents of this plant is important to find alternative sources of chlorophyll for health food supplements. This study aims to determine the chlorophyll contents of the bayhops in the coastal areas of Cilacap, i.e. Kamulyan, Bunton, and Sodong. The research method was experimental arranged in a completely randomized design of 6 treatments with three replications. The treatments used consisted of sea sand and soils from Kamulyan, Bunton, and Sodong. The parameters measured were the contents of chlorophyll a, chlorophyll b and total chlorophyll. The determination of chlorophyll contents was performed with acetone solvent, which was then measured by using a spectrophotometer. The results showed that growing habitat influences the chlorophyll contents. The bayhops found on further inland of Sodong contained the highest chlorophyll a, chlorophyll b and total chlorophyll.

摘要 Bayhops ( Ipomoea pes-caprae(L.) R. Br.)是一种生长在沿海地区的匍匐草本植物，能产生对人体有益的特定代谢物。对这种植物的叶绿素含量进行研究对于寻找替代的叶绿素来源作为保健食品补充剂非常重要。本研究旨在确定Cilacap 沿海地区即Kamulyan、Bunton 和Sodong 的月桂的叶绿素含量。研究方法为实验性安排，完全随机设计，6个处理，3个重复。使用的处理方法包括海沙和来自 Kamulyan、Bunton 和 Sodong 的土壤。测量的参数是叶绿素a、叶绿素b和总叶绿素的含量。叶绿素含量的测定用丙酮溶剂进行，然后用分光光度计测量。结果表明，生长的栖息地影响叶绿素含量。在更远的苏东内陆发现的月桂含有最高的叶绿素a、叶绿素b和总叶绿素。
