Abstract

Over the past decades, studies on bryophyte phytochemistry have been extensive, but there is a dearth of information regarding the effect of altitude on the phytochemical content in bryophytes. We carried out an evaluation on the phytochemical content of a tropical moss, Sphagnum junghuhnianum Dozy & Molk., at two different sites with contrasting altitude. The study was conducted on Mount Alab (1,800 m a.s.l.), representing low altitude site, and Mount Kinabalu (approximately 2,300 m a.s.l.), representing high altitude site. The total phenolics and flavonoids in S. junghuhnianum showed significant differenc e ( P 0.05) within populations at Mount Alab. In contrast, no significant difference was detected within populations at Mount Kinabalu. Total p henolics and flavonoids were relatively greater at Mount Kinabalu compared to Mount Alab, although no significan t difference was found. This study implies that within site variations such as soil nutrient content, amount of rainfall, rate of photosynthesis and light intensity may have a stronger effect on total phenolics and flavonoids in S. junghuhnianum.
