Abstract
This study aimed to investigate the effect of some topographic factors on the phenolic contents of the Arbutus andrachne L. plant. Plant samples (fruit) were collected from three aspects (south, west and north) at four altitudes (0-300, 300-600, 600-900, and ˃900m) in the countryside of Jableh in 2017. The fresh samples were squeezed, then the total contents of the phenolic compounds were determined by spectrophotometrically using Folin-Ciocalteu reagent, expressing the result in (mg gallic acid/100g fw) using spectrophotometer. The results showed that southern aspects recorded the highest yield of phenolic contents of fruits (40±0.53 mg/100g), followed by the western aspect (39.66±0.61 mg/100g), and finally the northern aspect (38.7±0.5mg/100g). Also it was noticed a gradual increase in phenolic contents in the first altitude (38.85±0.55 mg/100g), to the fourth altitude (40±0.8mg/100g). The results showed the effect of some topographic factors affected the phenolic contents of Arbutus andrachne L., where the phenolic contents from southern aspect were higher than that of the other aspects, and the fourth altitude (˃900m) was found to be the best in terms of the richness with phenolic compounds of the plant fruit of Arbutus andrachne L.
Key words: Arbutus andrachne L., Total phenolic, Altitude, Aspect.
