The objective was to evaluate the effect of different solvents on the total phenolic content and antioxidant activity of Brassica oleracea var. italica (broccoli). &lt;strong&gt;Methods: &lt;/strong&gt;The sample, consisting of stems and florets of Brassica oleracea var. italica (broccoli), were collected from the Chocas community in Carabayllo, Lima, Peru. Three extracts were prepared using different solvents, including a mixture of ethanol and water. The total phenolic content was determined using the Folin-Ciocalteu method, and antioxidant capacity was evaluated using two specific assays (DPPH and ABTS). Additionally, the correlation between total phenolic content and antioxidant activity was analyzed. &lt;strong&gt;Results:&lt;/strong&gt; The hydroethanolic extract demonstrated the highest phenolic content, with 686.02 mg GAE/100 g dry matter). It also exhibited strong antioxidant activity, measuring 1035.81 mg TE/100 g DM in the DPPH assay and 6506.94 mg TE/100 g DM in the ABTS assay. &lt;strong&gt;Conclusion: &lt;/strong&gt;The highest total phenolic content and antioxidant activity of Brassica oleracea var. italica were found in the hydroethanolic extract, which showed a significant high correlation. Frequent consumption of broccoli in the diet is recommended due to its high values.&lt;/p&gt;

Using methanol/dichloromethane and aqueous solvents, the extracts were produced. The antioxidant activity of the extracts was assessed by the 2,2-diphenyl-1- picrylhydrazyl assay, and their phenol content by the gallic acid method. The extracts were found to be inactive or weak against the HeLa (cervix), human cancer cell lines TK-10 (renal), and PC3 (prostate). It is suggested that these three human cell lines be tested against extracts of water and methanol/ dichloromethane at higher concentrations. The plant's leaf extract would also be the best substance to test against the human cell lines TK-10, PC-3, and HeLa. The IC50 values for two to three cell lines show that &lt;em&gt;T. violacea &lt;/em&gt;plant extracts (&amp;gt;100 g/ml) have no effect on cells. &lt;em&gt;T. violacea&lt;/em&gt; extract has greater antioxidant activity than the control. A thorough phenolic analysis showed that water leaf extract had the highest quantity of phenolics whereas bulb methanol/dichloromethane extract had the lowest. Both the methanol/dichloromethane and the aqueous extracts have the same characteristics for antioxidant activity. In order to enhance food's nutritional content and quality while also supporting excellent health, it has been found that phenolic compounds alter the color, flavor, and other sensory characteristics of the meal. Additionally, they help plants defend themselves against harm from ROS, molecular damage, microbial invasion, insects, and herbivores.&lt;/p&gt;

Br) is one of the typical plants of East Nusa Tenggara (NTT). Faloak contain flavonoid and polyphenol compounds, and show strong antioxidants activity which potentially correlated with its elastase inhibitory activity. Therefore, in this research, elastase inhibitory activity on various part of Faloak plant was investigated. &lt;strong&gt;Objective:&lt;/strong&gt; The purpose of this research was to investigate the elastase inhibitory activity, determination of total polyphenol, determination of total flavonoids, and also pharmacognosy characterization of Faloak leaves, roots, stems and stem barks. &lt;strong&gt;Methods:&lt;/strong&gt; Sample of leaves, roots, stems, and stem barks were extracted by 70% ethanol using ultrasound-assisted extraction (UAE). Phytochemical screening, microscopic identification and elastase inhibitory activity testing were performed on the leaves, roots, stems, and stem barks extract. This extract with the highest elastase inhibitory activity was then determined for its total polyphenol content and of total flavonoids content. &lt;strong&gt;Results:&lt;/strong&gt; UAE method with 70% ethanol successfully extracted active compounds from leaves, stems, roots, and stem barks of Faloak. Extract of all Faloak parts contained alkaloids, flavonoids, tannins, terpenes, and glycosides. The extract of Faloak stem barks showed the strongest elastase inhibitory activity as compared to the extract from other parts, with IC&lt;sub&gt;50&lt;/sub&gt; of 73.7 μg/mL. Alkaloid, flavonoid, tannin, terpene, and glycoside were detected as secondary metabolite in the extract of leaves, roots, stems and stem barks. The extract of Faloak stem barks showed the highest elastase inhibitory activity with IC50 73.7 μg/mL. The total flavonoids and total polyphenol content of Faloak stem bark extract were respectively 28.75 mg/gram and 45.25 mg/gram extract. &lt;strong&gt;Conclusion: &lt;/strong&gt;The 70% ethanol extract of leaves, roots, stems, and stem barks of Faloak showed elastase inhibitory activity, and stem barks extract showed the strongest activity. Faloak stem barks extract can be considered as potential to be developed as active compound in anti-aging product, both in cosmetic and pharmaceutical dosage forms.&lt;/p&gt;

This study was aimed to explore the lipid peroxidation inhibitory activity of polar extract of &lt;em&gt;M. parviflora&lt;/em&gt;.&lt;strong&gt; Methods:&lt;/strong&gt; The polar extract is the result of ethanol extract partition solved in acetone. The extract will keep polar components which are insoluble in acetone. Assayed methods applied are &amp;szlig;-carotene bleaching inhibition, thiobarbituric acid reactive substance (TBARS) measurement, and continuous monitoring of conjugated dienes formation in LDL. &lt;strong&gt;Results:&lt;/strong&gt; &lt;em&gt;M. parviflora&lt;/em&gt; extract inhibit &amp;szlig;-carotene/ linoleic acid oxidation, showed by IC&lt;sub&gt;50&lt;/sub&gt; value of 15.83 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml in 30th minute; but the potency will be reduced to IC&lt;sub&gt;50&lt;/sub&gt; value of 111.19 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml and 225.07 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml after the 60th and 120th minute of incubation. &lt;em&gt;M. parviflora&lt;/em&gt; extract inhibit MDA formation as for linoleic acid peroxidation product until the third day; at 20, 40, 60, 80 and 100 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml inhibit MDA formation as many as 29.16 &amp;plusmn; 2.41%, 4.24% &amp;plusmn; 43.27, 54.08 &amp;plusmn; 2.87%, 59.88 &amp;plusmn; 1.90%, and 69.75 &amp;plusmn; 2.32%, respectively. M. parviflora extract at 50 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml can inhibit LDL-oxidation induced by CuSO&lt;sub&gt;4&lt;/sub&gt;, performed by LDL-oxidation lag-time elongation until 70 minutes, similar ability was performed by epigallocathecin gallate at 5 &lt;em&gt;&amp;mu;&lt;/em&gt;g/ml. &lt;strong&gt;Conclusions:&lt;/strong&gt; &lt;em&gt;M. parviflora&lt;/em&gt; extract expressed relatively strong protection against lipid and LDL oxidation which can serve as the scientific basis of its development as a remedy for various diseases caused by lipid peroxidation.&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%">171</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mufidah Murdifin,&lt;sup&gt;1&lt;/sup&gt;* Ermina Pakki,&lt;sup&gt;1&lt;/sup&gt; Gemini Alam,&lt;sup&gt;1&lt;/sup&gt; Marianti A.
