“…The plant leaves from the oldest farm had the highest phenolic contents (12.41 mg g −1 ), while the stems of the youngest farm had the lowest (3.14 mg g −1 ). These values are lower than the 386.4 mg g −1 recorded in the flower residue of Taif's rose [47] and 4.21-25.02 mg g −1 recorded in Aloe spp. [40].…”

This study investigated the phytochemical contents of Taif’s rose pruning wastes and their potential application as phytomedicine, thereby practicing a waste-recycling perspective. In the Al-Shafa highland, four Taif rose farms of various ages were chosen for gathering the pruning wastes (leaves and stems) for phytochemical and pharmacological studies. The leaves and stems included significant amounts of carbohydrates, cardiac glycosides, alkaloids, flavonoids, and other phenolic compounds. The cardiac glycoside and flavonoid contents were higher in Taif rose stems, while the phenolic and alkaloid contents were higher in the plant leaves. Cardiovascular glycosides (2.98–5.69 mg g−1), phenolics (3.14–12.41 mg GAE g−1), flavonoids (5.09–9.33 mg RUE g −1), and alkaloids (3.22–10.96 mg AE g−1) were among the phytoconstituents found in rose tissues. According to the HPLC analysis of the phenolic compounds, Taif’s rose contains flavonoid components such as luteolin, apigenin, quercetin, rutin, kaempferol, and chrysoeriol; phenolics such as ellagic acid, catechol, resorcinol, gallic acid, and phloroglucinol; alkaloids such as berbamine, jatrorrhizine, palmatine, reticuline, isocorydine, and boldine. Warm water extract was highly effective against Bacillus subtilis, Escherichia coli, and Proteus vulgaris, whereas methanol and cold water extracts were moderately effective against Aspergillus fumigatus and Candida albicans. The study’s findings suggested that Taif’s rose wastes could be used for varied medical purposes.

“…Similarly, 2.0 ml of the DPPH solution and ethanol absolute are weighed separately. After mixing, the absorbance of blank ( A blank ) was determined at 517 nm (Liu et al., 2020). V C was used as the positive control and DPPH free radicals scavenging rates of samples were calculated according to Equation 1 (Qiu et al., 2017).…”

Tea polyphenol (TP)‐loaded alginate–collagen microspheres were prepared by ionic gelation method by Ca2+ as a cation and alginate as an anion. The morphology of the prepared microspheres was characterized by scanning electron microscopy. TP appeared in an amorphous state with an average size of 510.26 μm when encapsulated in the microspheres. The loading capacity (LC%) and encapsulation efficiency (EE%) were about 5.11% (w/w) and 33.51%, respectively. These microencapsulated beads were evaluated as a pH‐sensitive system for the delivery of tea polyphenol. At pH 7.4, the amounts of TP released increased significantly as compared with those released at pH 1.2. The 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical‐scavenging activity and the stability of the microencapsulated TP were higher than that of free TP. Overall, the TP microspheres could improve antioxidant activity and the storage stability of TP at room temperature for 6 months. Practical applications TP is widely used in the food industry, medicine, and daily health care because of its antioxidant and antibacterial effects. However, TP is sensitive to temperature, light, pH, oxygen, etc., which risks its stability during processing, storage, and transportation. The encapsulation using microspheres is of great significance for improving the antioxidant activity of TP. In conclusion, microspheroidization is an attractive approach to preserving TP efficiency during food processing and enables a targeted delivery upon consumption.

Chemical investigation of the ethanol extract of the branch and leaves of Illicium majus resulted in the isolation of four new phenylpropanoid glycosides (1–4) and one new phenolic glycoside (9), along with 13 known ones. Spectroscopic techniques were used to elucidate the structures of the new isolates such as 3‐[(2R,3S)‐7‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐3‐(hydroxymethyl)‐2,3‐dihydro‐1‐benzofuran‐5‐yl]propyl β‐D‐glucopyranoside (1), [(2R,3S)‐7‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐5‐(3‐hydroxypropyl)‐2,3‐dihydro‐1‐benzofuran‐3‐yl]methyl 2‐O‐α‐L‐rhamnopyranosyl‐β‐D‐glucopyranoside (2), [(2R,3S)‐7‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐5‐(3‐hydroxypropyl)‐2,3‐dihydro‐1‐benzofuran‐3‐yl]methyl 2‐O‐α‐L‐rhamnopyranosyl‐β‐D‐xylopyranoside (3), 3‐[(2R,3S)‐3‐({[2‐O‐(4‐O‐acetyl‐α‐L‐rhamnopyranosyl)‐β‐D‐xylopyranosyl]oxy}methyl)‐7‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐2,3‐dihydro‐1‐benzofuran‐5‐yl]propyl acetate (4), and 4‐(2‐hydroxyethyl)phenyl 3‐O‐β‐D‐glucopyranosyl‐β‐D‐glucopyranoside (9). Free radical scavenging activities of the isolates were elucidated through the DPPH assay method. The most active compounds, 1‐O‐caffeoyl‐β‐D‐glucopyranose (17) and soulieana acid 1 (18), exhibited moderate radical scavenging activities (IC50=37.7±4.4 μM and IC50=97.2±3.4 μM, respectively). The antibacterial activities of the isolates against Staphylococcus aureus and Escherichia coli were also assessed, and no activity was shown at the measured concentration (<32 μg/mL).
