Effect of altitude on total phenolics and flavonoids in Sphagnum junghuhnianum in tropical montane forests of Borneo
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...

| Summary: | 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. |
