The IC&lt;sub&gt;50&lt;/sub&gt; values of methanol extract from &lt;em&gt;Honeycrisp apple &lt;/em&gt;varied from 10.30 to 36.29 μg/ml which indicates the high radical scavenging activity of the sample. &lt;strong&gt;Conclusion:&lt;/strong&gt; The DNA damage defensive potential of the extracts was also revealed, which could be used in cancer inhibition.&lt;/p&gt;

The study report the quantification of phytochemical constituents and vitamin C contents from ethanol extracts of Solanum torvum fruits. &lt;strong&gt;Method:&lt;/strong&gt; The main objective for this research was to use standard procedures to determine phytochemical and vitamin C content. &lt;strong&gt;Results:&lt;/strong&gt; The estimated alkaloids found in mature fruits were 6.32 &amp;plusmn; 0.12 mg/g and 16.94 &amp;plusmn; 2.3 mg/g in the immature fruits. Total saponins in mature and immature fruits were 8.60 &amp;plusmn; 2.6 mg/g and 16.90 &amp;plusmn; 9.4 mg/g respectively. Total flavonoids in mature and immature fruits were 21.14 &amp;plusmn; 4.4 mg/g and 14.24 &amp;plusmn; 1.8 mg/g respectively. Also vitamin C contents were 11.79 &amp;plusmn; 2.0 mg/g in mature fruits and 8.70 &amp;plusmn; 0.26 mg/g in immature fruits. With the exception of alkaloids whose difference in the mature and immature was significant, other differences obtained were not significant. &lt;strong&gt;Conclusion:&lt;/strong&gt; The study showed that the extracts contain diversity of phytochemicals in appreciable amount that can expertly keep the body against oxidative stress triggered by free radicals and therefore be used as a source of potent natural products.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">946</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Desmond Ato Koomson&lt;sup&gt;1&lt;/sup&gt;, Benjamin Danso Kwakye&lt;sup&gt;2&lt;/sup&gt;, Williams Kweku Darkwah&lt;sup&gt;1,3&lt;/sup&gt;*, Bismark Odum&lt;sup&gt;3,4&lt;/sup&gt;, Mabel Asante&lt;sup&gt;5&lt;/sup&gt;, Gideon Aidoo&lt;sup&gt;6&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
