The aim of this study was to investigate the biological and chemical activity on two species of fungi of the genus Penicillium isolated from wastewater. On the selected species of fungi the different antioxidant activity assays were carried out: DPPH free-radical scavenging activity, total antioxidant activity, Fe2+- chelating ability and Fe3+- reducing power. Total phenol content was also determinate for ethanolic extract of mycelia. Penicillium chrysogenum ethanolic extract contained higher total phenolic content and better total antioxidant capacity as well as ferrous ion chelating ability. Penicillium fumiculosum ethanolic extract showed higher DPPH free-radical scavenging activity, as well as reducing power. Based on the obtained results it can be concluded that two types of fungi are potential new sources of natural antioxidants.

The research was conducted to explore the potency of pluchea leaves-black tea drink as antioxidant at various proportions. The research used a single factor randomized block design of pluchea leaves and black tea proportions, including 100:0; 75:25; 50:50; 25:75; and 0:100% (w/w). Each of it was repeated five times. The parameters observed in this study were secondary metabolites, total phenolic, total flavonoids, free radical DPPH scavenging activity, and iron reducing power. The data were statistically analyzed using Analysis of Variance (ANOVA) at α = 5%, if the analysis showed a significant effect then it was continued with Duncan's Multiple Range Test (DMRT). Data was stated as mean ± standard deviation. The results showed that the secondary metabolites containing in drink from pluchea leaves and black tea at various proportions were alkaloids, flavonoids, phenolics, saponins, tannins, and cardiac glycosides. The increasing of black tea proportion in samples added the intensity of alkaloids, phenolics, flavonoids, saponins, and cardiac glycosides compounds detected, but the tannins were decreased. These secondary metabolites were correlated with total phenolic content (TPC) and total flavonoid content (TFC). The increasing of black tea proportion in drink significantly decreased DPPH free radical scavenging activity and iron ion reducing power, except for 100% black tea proportion. Tannin compounds seems determining antioxidant activity.  Based on coefficient correlation between TPC or TFC and DPPH free radical scavenging activity or iron ion reducing power, the result showed that DPPH free radical scavenging activity was dominantly contributed by TPC and iron ion reducing power was determined by TPC and TFC. ABSTRAKPenelitian ini dilakukan untuk mengetahui potensi minuman daun beluntas teh hitam sebagai antioksidan pada berbagai proporsi. Penelitian ini menggunakan rancangan acak kelompok satu faktor, yaitu proporsi daun beluntas teh hitam meliputi 100:0; 75:25; 50:50; 25:75; dan 0:100% (b/b). Tiap faktor diulang sebanyak 5 kali. Parameter yang diamati pada penelitian ini meliputi kandungan metabolit sekunder, total fenolik (TPC), total flavonoid (TFC), kemampuan menangkal radikal bebas DPPH, dan kemampuan mereduksi ion besi. Data dianalisis secara statistik dengan Analysis of Variance (ANOVA) pada α = 5%, jika terdapat beda signifikan dilanjutkan dengan uji Duncan's Multiple Range Test (DMRT). Data dinyatakan dengan rata-rata ± standar deviasi.  Hasil menunjukkan bahwa metabolit sekunder yang terkandung dalam minuman daun beluntas teh hitam pada berbagai proporsi adalah alkaloid, flavonoid, fenolik, saponin, tannin, dan kardiak glikosida. Peningkatan proporsi teh hitam menambah intensitas senyawa alkaloid, fenolik, flavonoid, saponin, dan kardiak glikosida yang terdeteksi, tetapi kandungan senyawa tannin berkurang. Kandungan metabolit sekunder ini berkorelasi dengan total fenolik (TPC) dan total flavonoid (TFC). Peningkatan proporsi teh hitam dalam minuman menurunkan kemampuan menangkal radikal bebas DPPH dan kemampuan mereduksi ion besi, kecuali pada proporsi teh hitam 100%. Kandungan senyawa tannin dalam minuman menentukan aktivitas antioksidan. Berdasarkan koefisien korelasi antara TPC atau TFC dan kemampuan menangkal radikal bebas DPPH atau kemampuan mereduksi ion besi, hasil menunjukkan bahwa kemampuan menangkal radikal bebas DPPH dominan dikontribusi oleh TPC dan kemampuan mereduksi ion besi ditentukan oleh TPC dan TFC.

Background: The mulberry tree, a plant of the family Moraceae and the genus Morus, has been widely cultivated to feed silkworms. Various parts of Morus alba linn used as an Anti-inflammatory, hypoglycemic, cardioprotective, hepatoprotective, free radical scavenging activity and neuroprotective agent. The plant contains flavonoids, moranoline, albanol, morusin coumarine, and stilbene, which have. In this study, anticonvulsant property of Morus alba leaves extract (MAE) was evaluated by using MES and PTZ induced convulsion in rats.Methods: Effects of MAE were evaluated in experimental models of electro convulsions, maximal electro shock (MES) and chemoconvulsion induced by pentylenetetrazole (PTZ) in rats (n=6), which were treated intraperitonially with doses of 100, 200 and 400mg/kg.Results: The duration of tonic hind limb extension (seconds) with MAE in MES induced convulsions at dose of 100, 200, 400 mg/kg is 8.33±1.21, 6.83±1.16 & 3.16±0.98 respectively. In the dose of 400 mg/kg of MAE showed highly significant results by reducing the duration of tonic hind limb extension in MES induced convulsions. And onset of jerky movements (seconds) with MAE in PTZ induced convulsions at dose of 100, 200, 400mg/kg is 157.83±8.99, 195.66±17.02 and 295.50±21.10 respectively. In the dose of 400mg/kg of MAE showed highly significant results by delaying the onset of convulsions.Conclusions: Results indicate that the MAE have anticonvulsant effects in MES induced convulsions and in PTZ induced convulsions.

Abstract Bitter herbs (Sambiloto) have many pharmacological activities including antioxidant, antidiabetic, anticancer, antihyperlipidemic and anti-inflammation. Andrographolide is a diterpene compounds contained in bitter herbs. It is known that andrographolide compound responsible for the pharmacological activity of the bitter herbs. This study investigated DPPH free radical scavenging activity from andrographolide diterpene lactone. This study was initiated with the isolation of andrographolide compound from bitter herbs and then testing their DPPH free radical scavenging. The results suggested that andrographolide had IC50 value of 5.45 mg. This means andrographolide has 50% DPPH inhibition effect, i.e 5.45 mg.

This study was undertaken to evaluate the antioxidant and anti-hemolytic properties of Algerian Drimia maritima Baker flower extracts. Determination of phenolic content was carried out to estimate the chemical composition of D. maritima extracts. Antioxidant properties were investigated in all extracts using free radical scavenging activity (against DPPH, ABTS, hydroxyl radical, and superoxide anion), reducing power, inhibition of lipid peroxidation, and anti-hemolytic capacity. Phenolic determination revealed that D. maritima flowers contain phenolic compounds, flavonoids, and tannins. Ethyl acetate extract showed the highest reducing power and scavenging activity using DPPH and ABTS assays. However, aqueous extract was the most effective against hydroxyl radical, superoxide anion, and lipid peroxidation. The half-time of hemolysis indicates that chloroform extract exhibited the best anti-hemolytic capacity in the AAPH induced hemolysis model. The results of this study suggest that D. maritima could be used as a possible source of antioxidant phenolic compounds and that further determination of these compounds may provide more information on their medicinal value.  Keywords: Drimia maritima, phenolic compounds, scavenging activity, reducing power, anti-hemolytic.

A process for preparation of a microgreen and fruit based beverage was optimized using spinach (Spinacia oleracea) microgreen, pomegranate (Punica granatum), pineapple (Ananascomosus) and sugar. The blended juice in different ratios was analysed for total soluble solids, viscosity, sedimentation, acidity, metal chelation activity, free radical scavenging activity and reducing power. The optimized beverage had, 17.26 mL 100 mL-1 spinach microgreen juice, 57.07 mL 100 mL-1 pomegranate juice, 1.01 g 100 g-1 sugar and 24.66 mL 100 mL-1 pineapple juice. The product was high in nutrients, particularly protein, minerals (sodium, potassium and iron), vitamins (vitamin C), bioactive compounds (total phenols and total carotenoids) and had high antioxidant activity (metal chelation activity, free radical scavenging activity and reducing power). The antioxidants and bioactive compounds present in juice were designed to help reduce oxidative stress during inflammatory cases such as arthritis.
