“…The content of total phenols in Fritillaria straw was 26.56 ± 1.36 mg GAE/g dw, and the content of total flavonoids was 18.75 ± 0.80 mg RE/g dw. These values are higher than the phenolic and flavonoid content detected in ethanolic extracts of other edible plants, such as the contents of total phenols and flavonoids of pomegranate were 17.6 ± 2.3 mg GAE/g dw and 1.9 ± 0.3 mg RE/g dw (Mahboubi et al., 2015), the contents of total phenols and flavonoids of Salak fruit were 6.78 ± 1.18 mg GAE/g dw and 8.54 ± 0.09 mg RE/g dw (Tan et al., 2020), and the contents of total phenols and flavonoids of Artemisia campestris were 2.43 ± 0.62 mg GAE/g dw and 22.08 ± 2.13 mg RE/g dw (Tlili et al., 2013), which proved the antioxidative and anti‐microbial activity of FSE.…”

Fritillaria cirrhosa D. Don, which can be used for medicine and food, contains a variety of chemicals including polyphenols, alkaloids, terpenoid, and others that have beneficial biological properties like antihypertension, bacteriostasis, and anti‐inflammatory. The ethanolic extract of Fritillaria straw was obtained for this study using ultrasonic‐aided extraction, and the amounts of total phenols and total flavonoids were 26.56 ± 1.36 mg GAE/g dw and 18.75 ± 0.80 mg RE/g dw, respectively. Ultra‐performance liquid chromatography–quadrupole time‐of‐flight–mass spectrometry technology was utilized to identify 50 major chemicals in the Fritillaria straw extract (FSE). Meanwhile, the antioxidative activities of FSE were evaluated by 2,2‐diphenyl‐1‐picrylhydrazyl, 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) and Ferric reducing antioxidant power assays in vitro, which pointed out the antioxidative potential of FSE. Additionally, 0.1%, 0.5%, and 1% of FSE and 0.02% butylated hydroxyanisole (BHA) + butylated hydroxytoluene (BHT) (1:1) were separately added to Chinese‐style sausage to study their effects on the lipid oxidation, protein oxidation, and quality of the sausage at different storage times. The study found that the effect of adding 1% FSE on carbonyl content, total volatile basic nitrogen, and TVC of sausage could achieve the effect of the 0.02% BHA + BHT (1:1) group on the 35th day, and the thiobarbituric acid reactive substances value and peroxide value of sausage were significantly lower than the control group. Therefore, as one of the candidates to replace synthetic antioxidants, the FSE can be used in the production of Chinese sausages, which has a positive effect on improving the product's quality and extending the shelf life.Practical ApplicationThe antioxidative activities of 50 main compounds were identified after the ethanolic extraction of Fritillaria straw. This Fritillaria straw extract was added to Chinese sausage, effectively inhibiting the oxidation of lipids and proteins as well as the decomposition of proteins. Obviously, the Fritillaria straw extract, one of the choices to replace synthetic antioxidants, may be useful for future meat processing, because of its positive impact on the product's quality and shelf life.

Pulasan (Nephelium mutabile Blume) is an underutilized fruit native to tropical countries, including Malaysia, Thailand, and Indonesia. To date, the medicinal potential of pulasan remains unexplored, although this fruit shares the same genus with the well-known rambutan (Nephelium lappaceum). Therefore, the current study aims to examine the antioxidant properties of different parts of pulasan (flesh, rind, and kernel) and investigate the bioactive profile, anti-hypertensive and hypoglycemic properties of pulasan rind. Pulasan were extracted using different solvents, including distilled water, methanol, and ethanol. The antioxidant capacity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP), and the antioxidant component was identified by total flavonoid content (TFC) and total phenolic content (TPC). The bioactive profile of pulasan rind was characterized by high-performance liquid chromatography (HPLC). The anti-hypertensive and hypoglycemic properties of pulasan rind were determined with angiotensin-converting enzyme (ACE) assay and alpha-amylase inhibition assay, respectively. Emerging findings revealed that pulasan rind exhibited the highest antioxidant capacity (DPPH, TEAC, and FRAP) in all extraction solvents and antioxidant components (TPC and TFC) in ethanolic extract. The ethanolic extracts of pulasan rind also had higher ACE and alpha-amylase inhibition activities than the distilled water extracts. Geraniin, chlorogenic acid, catechin, corilagin, syringic acid, and naringenin of pulasan rind may function as anti-hypertensive agents.

“…Tilaar et al (2017) have stated that several studies have proved that snake fruit has antioxidant activity that can be used for any purposes. The methanol extracts of the fruits showed a high antioxidant activity accompanied by its anti-hypertensive and anti-diabetic effects (Tan et al, 2020). Suica-Bunghez et al (2016) revealed that the antioxidant activity of snake fruit is caused by the content of polyphenol, flavonoid, tannin and monoterpenoid compounds.…”

Snake fruit (Salacca zalacca (Gaertner) Voss) is one of indigenous fruits from Southeast Asia that has been consumed for its antioxidant contents. Improving the fruit quality might increase its benefits for human health. This study aims to analyze fruit morphology, antioxidant activity, total phenolic and flavonoid contents of the fruit applied with goat manures and Bacillus velezensis B-27. The research used two-factor Randomized Complete Block Design (RCBD) with three blocks as replications. The first factor is the level of goat manure application i.e. 0 kg plant-1, 5 kg plant-1 and 10 kg plant-1, while the second factor is the bacteria application i.e. applied with Bacillus velezensis B-27 and without Bacillus velezensis B-27. The research was conducted in June until December 2019 at Turi, Sleman, Yogyakarta, Indonesia. Fruit length, diameter and shape were measured as morphology parameters. Antioxidant activities were measured using 2,2-Diphenyl-1-picrylhydrazyl, whereas flavonoid and phenolic contents were determined by the aluminium-chloride colorimetric and Folin-Ciocalteu methods, respectively. Means of each parameter were analyzed using ANOVA, continued with the Tukey’s HSD test at a 5% significance level. The result showed that the application of 10 kg goat manure per plant with bacteria increased the fruit length (76.78 mm) and the diameter (62.72 mm). Addition of 10 kg goat manure per-plant combined with Bacillus velezensis B-27 gave the highest antioxidant (IC50 of 37.83 µg.mL-1), flavonoid (5.35 mgGAE.100 g-1) and total phenolic contents (44 mgQE.100 g-1).
