Hylocereus polyrhizus cultivation started in Taiwan around the 1980s. The pulp of the fruit is edible and contains small, black, and soft seeds. The peel of the fruits are covered with bracts. The H. polyrhizus fruit is known to be rich in nutrients and minerals. To evaluate the potential applications of the agricultural wastes of H. polyrhizus, the stem, peel, and flower of H. polyrhizus were extracted with solutions of ethanol and water mixed in different ratios. Data was collected for the H. polyrhizus extract including the yield of total phenolics, the total flavonoids, and antioxidant activity, as determined by the 2-2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging assay. The protective effects of H. polyrhizus extract on DNA was investigated using an assay with the pUC19 plasmid. The cell proliferation and migration effects were evaluated in the NIH-3T3 fibroblast cell line. The greatest yield of extract from the stem of H. polyrhizus was 44.70 ± 1.77% which was obtained using 50% aqueous ethanol and the greatest yield of extract from the peel was 43.47% using distilled water. The stem extract, which was prepared with 95% aqueous ethanol, had the highest composition of phenolics and flavonoids as well as the best DPPH radical scavenging activity. The stem extract had excellent ABTS radical scavenging activity as well. The stem, peel, and flower extracts, which were prepared using 95% aqueous ethanol, showed excellent results in protecting themselves from DNA damage, similar to the effect of 0.3 mg/mL ferulic acid. None of the extracts were able to promote cell proliferation at concentrations of 250 μg/mL to 2,000 μg/mL in a 24 h period. The 1000 μg/mL stem and flower extracts in 95% aqueous ethanol promoted considerable cell migration after a 24 h period.

Abstract Background Strobilanthes heyneanus (Nilgirianthus heyneanus) belongs to the family Acanthaceae that contains many species with potential for diverse medicinal uses. It is also called ‘Karun kurinji’ and is commonly found in the South-West regions of India. The species are commonly used in rheumatic complaints, sprain of the ankle, and hernia. The objectives of the study were to evaluate the antioxidant activity, phytochemical analysis, and antibacterial activities of the root extract of S. heyneanus. Results The radical scavenging and reduction assays such as DPPH● radical and OH● radical scavenging assays, as well as phosphomolybdenum reduction and Fe3+ reducing power assays, were determined for the root extract. The highest DPPH● radical scavenging activity was 88.23 ± 1.32 at 120 μg/mL concentration, and the calculated IC50 was 38.52 μg/mL concentration. The highest OH● radical scavenging activity was 51.28 ± 1.06 at 120 μg/mL concentration, and the calculated IC50 was 51.28 μg/mL concentration. The highest ABTS●+ radical scavenging activity was 91.28 ± 1.12 at 30 μg/mL concentration, and the calculated IC50 was 33.92 μg/mL concentration. The highest phosphomolybdenum reduction was 87.43 ± 0.90 at 120 μg/mL concentration, and the calculated RC50 was 24.74 μg/mL concentration. The highest Fe3+ reduction was 89.38 ± 0.98 at 120 μg/mL concentration, and the calculated RC50 was 31.06 μg/mL concentration. The antibacterial activity of S. heyneanus showed the highest zone of inhibition of 24 mm for Salmonella typhi with 500 μg/mL concentration. The cytotoxicity limits of the root extracts were tested by MTT assay using human dermal fibroblast cell lines, reflecting > 90% cell viability at a concentration of 500 μg/mL. Conclusions The current study showed that the root extract of S. heyneanus has better antioxidant properties and potential anti-bacterial compounds. The phytochemical analysis of the root extract showed the presence of alkaloids, steroids, terpenoids, phenols, flavonoids, tannins, saponins, glycosides, and carbohydrates, which are responsible for the antibacterial root extract of S. heyneanus synergistically.

Fridericia chica (Bignoniaceae) is a traditional medicinal plant. The aim of this research was to determine the protective effects of the hydroethanolic extract from the F. chica leaves (HEFc) against the cytotoxicity of zearalenone (α-ZEL) and β-ZEL on SH-SY5Y cells. Free radical scavenging activity of HEFc was evaluated using the DPPH method. The cytotoxicity of both zearalenone metabolites and HEFc was examined using MTT test, as was the cytoprotective effects of the HEFc on cells treated with these mycotoxins. The chemical composition of HEFc was determined using UPLC-QTOF-MS/MS. HEFc elicited good DPPH radical scavenging activity following a concentration-dependent relationship. Cells exposed to α-ZEL exhibited a viability ˂50% after 48 h of treatment (25 and 50 µM), while those exposed to β-ZEL showed viability ˂50% (100 µM) and ˂25% (25-100 µM) after 24 and 48 h of exposure, respectively. HEFc showed a significant increase in cell viability after exposure to α-ZEL (25 and 50 µM) and β-ZEL (6–100 µM) (p < 0.05). UPLC-QTOF-MS/MS analyses allowed the identification of 10 phytochemical components in the HEFc. In short, the hydroethanolic extract of F. chica grown in Colombian Caribbean can protect against the effects of mycotoxins and it is a valuable source of compounds with antioxidant properties.

Gac fruit (Momordica cochinchinensis Spreng) is mostly found in southeast Asian countries. Previous studies have demonstrated that gac fruit is a major source of β-carotene, lycopene, and α-tocopherol. This study aimed to develop the extraction of Thai gac fruit as a potential active ingredient for antioxidant, melanogenesis, and collagen stimulating activities. In the present study, different parts of ripe Thai gac fruit, the peel, pulp, and seed membrane, were extracted using the accelerated solvent extraction (ASE) technique, an innovative plant extraction method. DPPH radical-scavenging activity, ABTS radical scavenging activity, and ferric reducing/antioxidant power (FRAP) assay were performed to compare the antioxidant activity derived from each part of the fruit. The effect of Thai gac fruit on melanogenesis and collagen stimulating activities was investigated using B16F1 and human fibroblast cell lines, respectively. The results demonstrate that the pulp (EC50 value of 7.42 ± 0.81 mg/mL) and the seed membrane (EC50 value of 76.43 ± 2.66 μg/mL) showed the strongest antioxidant activities in DPPH and ABTS assay, respectively. The peel clearly displayed the strongest antioxidant activity and significantly increased the FRAP value (247.67 ± 19.73 μM/mg). Furthermore, the peel showed the lowest melanin content (76.56 ± 7.13 % of control) in the B16F1 cell line, and clearly increased the most amount of collagen (21.87 ± 3.12%) in the human fibroblast cell line in comparison to the other fractions. Therefore, Thai gac fruit peel revealed the biological effects, including antioxidant, melanogenesis, and collagen stimulating activities. In conclusion, Thai gac fruit extracted using the ASE technique exhibited several effects that could be used as a potential active ingredient for cosmeceutical products, due to its antioxidant, melanogenesis, and collagen stimulating activities. Our findings provide potential uses of Thai gac fruit as a multifunctional cosmeceutical ingredient to be further explored in future studies.

Five different proteases were used to hydrolyze the swim bladders of Nibea japonica and the hydrolysate treated by neutrase (collagen peptide named SNNHs) showed the highest DPPH radical scavenging activity. The extraction process of SNNHs was optimized by response surface methodology, and the optimal conditions were as follows: a temperature of 47.2 °C, a pH of 7.3 and an enzyme concentration of 1100 U/g, which resulted in the maximum DPPH clearance rate of 95.44%. Peptides with a Mw of less than 1 kDa (SNNH-1) were obtained by ultrafiltration, and exhibited good scavenging activity for hydroxyl radicals, ABTS radicals and superoxide anion radicals. Furthermore, SNNH-1 significantly promoted the proliferation of HUVECs, and the protective effect of SNNH-1 against oxidative damage of H2O2-induced HUVECs was investigated. The results indicated that all groups receiving SNNH-1 pretreatment showed an increase in GSH-Px, SOD, and CAT activities compared with the model group. In addition, SNNH-1 pretreatment reduced the levels of ROS and MDA in HUVECs with H2O2-induced oxidative damage. These results indicate that collagen peptides from swim bladders of Nibea japonica can significantly reduce the oxidative stress damage caused by H2O2 in HUVECs and provides a basis for the application of collagen peptides in the food industry, pharmaceuticals, and cosmetics.
