Isolation of Lasiodiplodin and Evaluation of some Biological Activities of the Stem Barks of Phyllanthus Albizzioides (Kurz) Hook.f.
A large number of the plants are claimed to possess the antibiotic properties in the traditional system and are also used extensively by the tribal people throughout the world. It is now mostly thought that nature has given the cure of every disease in one form or another. Plants have been known to cure people from various diseases in Ayurveda. This research focused on the screening of phytochemicals and some biological activities of Phyllanthus albizzioides. The research showed that the ethanol extracts were found to be greater chemical constituents than watery extracts. Among the chemical constituents, steroid compounds were observed in highest amount in ethanol extract and the second highest in flavonoid compounds followed by tannin compounds and pheolic compounds. Furthermore, the ethanol extracts were more effective than the watery extracts in all tested biological activities such as antioxidant, anti-diabetic, cytotoxicity, antimicrobial, antitumor and NO inhibition activities. A cyclohexanone compound was isolated from the chloroform extract of the stem bark of P. albizzioides. The relative structure was determined to be 4,5-dihydroxy-3-methyl-cyclohex-2-enone on the basic of HRESIMS, 1H NMR and 13C NMR spectroscopic analyses, including 2D NMR experiments.
