One way to reduce melanin formation is by inhibiting the enzyme tyrosinase. Often discarded as waste, avocado leaves and seeds are rich in flavonoids with potential tyrosinase-inhibiting properties. &lt;strong&gt;Objectives:&lt;/strong&gt; This study aimed to perform phytochemical screening, measure antioxidant and tyrosinase inhibitor activities, and explore the correlation between free radical scavenging and tyrosinase inhibition in ethanol extracts of young avocado leaves (EAL(O)) and old avocado leaves (EAL(Y)), as well as the ethyl acetate extract of avocado seeds (EAS). &lt;strong&gt;Methods:&lt;/strong&gt; Antioxidant activity was assessed using the &lt;em&gt;2,2-Diphennyl-1-picrylhydrazyl &lt;/em&gt;(DPPH) method, while tyrosinase inhibition was evaluated in vitro with mushroom tyrosinase and L-DOPA as a substrate. &lt;strong&gt;Results: &lt;/strong&gt;The results of the antioxidant activity test using the DPPH method yielded IC&lt;sub&gt;50&lt;/sub&gt; values for EAL(Y), EAL(O), and EAS of 17.9±0.15 μg/mL, 15.33±0.02 μg/ mL, and 745.66±6.08 μg/mL, respectively. Tyrosinase inhibition tests indicated that EAL(Y), EAL(O), and EAS could significantly inhibit tyrosinase activity (&lt;em&gt;P &lt;/em&gt;&amp;lt;0.01), with IC&lt;sub&gt;50&lt;/sub&gt; values of 10133.26±140.12 μg/mL, 8496.20±155.06 μg/mL, and 48375.8±553.06 μg/mL, respectively. The correlation coefficients between tyrosinase inhibition and antioxidant activity for EAL(Y), EAL(O), and EAS were r = 0.955, r = 0.947, and r = 0.991, respectively. &lt;strong&gt;Conclusion: &lt;/strong&gt;These findings suggest that EAL(Y), EAL(O), and EAS may be potential natural skin-whitening agents due to their flavonoid content and antioxidant and anti-tyrosinase properties.&lt;/p&gt;

Consumption of soy products has been reported to reduce the incidence of and mortality rate for some cancers, including breast cancer. However, there are limited &lt;em&gt;in vivo&lt;/em&gt; studies on the inhibitory effect of soybean extracts on breast cancer. &lt;strong&gt;Objectives:&lt;/strong&gt; To examine the effect of soybean extracts on breast cancer cellular immunity and to determine the role of CD4&lt;sup&gt;+&lt;/sup&gt; and CD8&lt;sup&gt;+&lt;/sup&gt; T cells in the development and outcome of breast cancer. &lt;strong&gt;Material and Methods:&lt;/strong&gt; Rat were induced with DMBA 11 times to get a breast cancer model. A soybean extract was given at different doses starting one week before DMBA induction and continued until the end of the study. At the end of the study, peripheral blood was collected, and the lymphocytes were examined using flow cytometry. &lt;strong&gt;Results:&lt;/strong&gt; The phytochemical screening of soybean extract, using the Q-TOF LC/MS method, detected four bioactive components from the isoflavone and saponin groups. The incidence of tumor formation in the NeC, SE-D250, SE-D500, and SE-D1000 groups was 100%, 83%, 33%, and 33%, respectively. The highest proportion of CD4+ T cells was found in the NeC (69.35%), while the lowest was in the SE-D1000 (63.75%). The highest and lowest proportions of CD8+ T cells were found in the SE-D1000 and NeC groups, at 35.95% and 31.15%, respectively. &lt;strong&gt;Conclusions:&lt;/strong&gt; The soybean extract was able to reduce the incidence of breast tumor formation in DMBA-induced rat in a dose-dependent manner. The soy extract group's CD4+/CD8+ ratio was close to that of healthy rats compared to the DMBA-induced group without soy extract. A lowered CD4+/CD8+ ratio is followed by a lower risk of tumor formation.&lt;/p&gt;
