Comparative Study of Chlorophyll Content in Leaves of Thai Morus alba Linn. Species

Chlorophyll is an antioxidant which usually found in nature especially in green leafy plants. The experiment study had an objective to evaluate the content of chlorophyll A in two species of mulberry, Nakhorn Ratchasrima-60 and Burirum-60. The two species of mulberry were extracted by 95% ethanol as a solvent and the chlorophyll A extraction was collected and detected by spectrophotometer by mean of 2 wavelengths, 420 and 680 nm. The experiments were repeated 3 times and chlorophyll A was calculated by using the equation of Lorenzen. The results showed that the amounts of chlorophyll A from Nakhorn Ratchasrima-60 Strain were 15-929, 24.212 and 20.112 mg L￣1 with the average of 20.084 mg L￣1 and from Burirum-60 were 19.641, 21.137 and 18.713 mg L￣1 with the average was 19.668 mg L￣1. The amount of chlorophyll A content in Nakhorn Rachasrima-60 species were slightly higher than in Burirum-60 species.
