The purpose of this study is to evaluate the phytochemicals and antioxidant activity of leaves and roots of &lt;em&gt;Raphanus sativus &lt;/em&gt;of Saudi origin. Various phytochemicals were screened in n-hexane, chloroform, ethyl acetate and aqueous fractions of leaves and roots of &lt;em&gt;Raphanus sativus &lt;/em&gt;using standard protocols and IR screening method. Total phenolic (TPC) and flavonoid (TFC) contents were assessed by Folin-Ciocalteau and aluminium chloride methods respectively. The antioxidant activity was evaluated by DPPH antioxidant protocol, using trolox as standard. Results demonstrated that &lt;em&gt;Raphanus sativus&lt;/em&gt; chemically characterized by the availability of various constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels in fractions of leaves and roots of&lt;em&gt; Raphanus sativus&lt;/em&gt; and the absence of cardiac glycosides, anthraquinones and alkaloids which was further confirmed using FTIR analysis. TPC was ranged from (8.92±1.01) and (211.80±1.57) mg GAE/g extract and TFC was ranged from (0.036±0.03) and (11.57±0.60) mg QE/g extract for leaves and roots extracts respectively. Due to the high phenolic and flavonoid content in aqueous and ethyl acetate fractions of leaves and roots extracts , results demonstrated high antioxidant activity with IC&lt;sub&gt;50&lt;/sub&gt;: (56.3±1.3) and (69.7±1.8) for aqueous fractions and (47.2±1.5) and (58.7±0.7) for ethyl acetate fractions of leaves and roots extracts respectively Study revealed that ethyl acetate and aqueous fractions of leaves and roots of&lt;em&gt; Raphanus sativus &lt;/em&gt;could develop a potential natural antioxidant herbal remedy. The study recommends future investigation to isolate and identify the bioactive secondary metabolites in &lt;em&gt;Raphanus sativus.&lt;/em&gt;&lt;/p&gt;

Bitter melon leaves (&lt;em&gt;Momordica charantia&lt;/em&gt; L.) has been traditionally utilized to treat hypertension, yet not many studies explained the antihypertension effect of this plant. &lt;strong&gt;Methods:&lt;/strong&gt; This study was conducted to test the benefit of bitter melon leaves as antihypertension using angiotensin converting enzyme inhibition activity in 80% ethanolic extract and its fractions (n-hexane, ethyl acetate, and n-butanol) using ACE kit-WST (Dojindo, Japan). Then the antihypertension activity was associated with the phenolic content which was expressed in gallic acid equivalent (GAE) and total flavonoid in quercetin equivalent (QE). &lt;strong&gt;Results:&lt;/strong&gt; Result of the study showed that the IC&lt;sub&gt;50&lt;/sub&gt; value obtained from the ethanolic extract to inhibit ACE activity was 7.52 &amp;mu;g/mL and the highest inhibition obtained in ethyl acetate fraction with IC&lt;sub&gt;50&lt;/sub&gt; value was 4,29 &amp;mu;g/mL. Phenolic total and flavonoid total determination also showed that the highest content obtained in ethyl acetate fraction with 18.752 mg GAE/gr extract and 8.310 mg QE/gr extract, respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; According to the study, it could be concluded that bitter melon (&lt;em&gt;Momordica charantia&lt;/em&gt; L.) leaves provide inhibition activity against Angiotensin Converting Enzyme (ACE) and chemical compounds that were expected to play an active role in inhibiting ACE were flavonoid and tannin.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">252</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Putri Lestari, Katrin, Rissyelly*, Putu Gita Maya Widyaswari Mahayasih&lt;/strong&gt;&lt;/p&gt;
