Diets rich in fruits and vegetables have been associated with reduced risks for many types of cancers. Avocado (Persea americana Mill.) is a widely consumed fruit containing many cancer preventing nutrients, vitamins and phytochemicals. Studies have shown that phytochemicals extracted from the avocado fruit selectively induce cell cycle arrest, inhibit growth, and induce apoptosis in precancerous and cancer cell lines. Our recent studies indicate that phytochemicals extracted with 50% Methanol from avocado fruits help in proliferation of human lymphocyte cells and decrease chromosomal aberrations induced by cyclophosphamide. Among three concentrations (100 mg, 150 mg and 200 mg per Kg Body Weight), the most effective conc. of extract was 200 mg/Kg Body Wt. It decreased significant level of numerical and structural aberrations (breaks, premature centromeric division etc. up to 88%, p < 0.0001)), and accrocentric associtation within D & G group (up to 78%, p = 0.0008). These studies suggest that phytochemicals from the avocado fruit can be utilized for making active chemoprotective ingredient for lowering the side effect of chemotherapy like cyclophosphamide in cancer therapy.
