5. Conclusion
From the study, it may be concluded that leaves crude extracts
of neem are a good source of phytochemicals. Different extracts
showed significant total phenolics and flavonoids contents.
Hence, further studies are needed to isolate pure
compounds from the crude extract and to better understand
the mechanism of such actions scientifically.
