Abstract:

The roots sample of phyllanthus muellerianus was extracted with Hexane and Methanol respectively, given the percentage yield of 2.37% and 10.18% respectively. Column chromatography of the Methanol extract afforded 3 crystals which were labeled as M, N, Q. IR and The UV analysis shows that M gave absorption peaks at 238nm and 326nm, Q gave absorption peaks at 240nm and 326nm while N gave peaks at 220nm and 240nm. The IR analysis shows absorption for M at 1378^-1 and Q at 1378.5cm^-1, also, there are other absorption band for M, N and Q at 1465.9cm^-1, 1475.6cm^-1 and 1470.9cm^-1 respectively which suggest C-H bending of saturation. It was also shown that there are absorption of M,N and Q at 1704.3cm^-1, 1699.4cm^-1 and 1699.4cm^-1 respectively. Other absorption for M and Q at 1704.^-1 and 1699.4cm^-1 which suggest C-H sretching and absorption at 2939.8^-1 and 2934.8cm^-1 which indicate the aldehyde functional group. Furthermore, absorptions were shown for M, N and Q at 3446.5cm^-1, 3440.7c^-1 and 3438.2cm^-1 respectively which suggest O-H stretching.
