Essential Oil Compounds of Andaliman (Zanthoxylum acanthopodium DC.) Fruit Varieties and Their Utilization as Skin Anti-Aging Using Molecular Docking

Exposure to UV/infrared (IR) radiation is the main extrinsic factor that changes skin morphology and affects the increase in reactive oxygen species (ROS) in skin aging. Ten varieties of andaliman (Zanthoxylum acanthopodium DC.) fruit are presumed to have skin anti-aging compounds via an enzyme-inhibition mechanism. This study aims to compare ten essential oils (EOs) of andaliman fruit varieties, group them according to their varieties, and obtain the chemical components that can be used as potential skin anti-aging agents using molecular docking. EOs were isolated by hydrodistillation, and the determination of the chemical compounds was performed using gas chromatography-mass spectrometry (GC-MS). Using the Orange data mining software, a heatmap was used for grouping and showing the abundance of the compounds of ten varieties. Finally, molecular docking was conducted using the software AutoDockTools 1.5.7. There were 97 chemical components in the ten EOs of andaliman fruit varieties, with the main chemical components being geranyl acetate (29.87%) and D-limonene (26.49%), and they were grouped into three clusters. The chemical components that are prospective candidates as skin anti-aging agents are geranyl acetate and D-limonene, found in abundance in the Sihalus variety of andaliman fruit. These can be developed for applications in the pharmaceutical industry.

Comparative transcriptomics reveals unique pine wood decay strategies in the Sparassis latifolia

Sparassis latifolia is a valuable edible mushroom, growing on fresh pine wood sawdust substrate. However, the mechanistic bases are poorly understood. The gene expression profiles of S. latifolia were analyzed from submerged cultures with fresh pine wood sawdust substrate for different time (0 h, 1 h, 6 h, 1 day, 5 days, and 10 days, respectively). The total number of differentially expressed genes (DEGs) identified under pine sawdust inducing was 2,659 compared to 0 h (CK). And 1,073, 520, 385, 424, and 257 DEGs were identified at the five time points, respectively. There were 34 genes in common at all inoculated time points, including FAD/NAD(P)-binding domain-containing protein, glucose methanol choline (GMC) oxidoreductase, flavin-containing monooxygenase, and taurine catabolism dioxygenase. Weighted gene co-expression analysis (WGCNA) was then used to compare the molecular characteristics among the groups and identified that the blue module had the highest correlation with the time induced by pine wood sawdust. There were 102 DEGs out of 125 genes in the blue model, which were most enriched in nitronate monooxygenase activity, dioxygenase activity, and oxidation-reduction process GO terms (p < 0.05), and peroxisome in KEGG pathway. This may provide clues into mechanisms that S. latifolia can grow on fresh pine wood sawdust substrate.

GC-MS Profiling, Anti-Helicobacter pylori, and Anti-Inflammatory Activities of Three Apiaceous Fruits' Essential Oils

Eradication of Helicobacter pylori is a challenge due to rising antibiotic resistance and GIT-related disorders. Cuminum cyminum, Pimpinella anisum, and Carum carvi are fruits belonging to the Apiaceae family. Their essential oils were extracted, analyzed using GC-MS, tested for anti-H. pylori activity by a micro-well dilution technique, identified for potential anti-H. pylori inhibitors by an in-silico study, and investigated for anti-inflammatory activity using a COX-2 inhibition assay. Results showed that the main components of C. cyminum, P. anisum, and C. carvi were cumaldehyde (41.26%), anethole (92.41%), and carvone (51.38%), respectively. Essential oil of C. cyminum exhibited the greatest anti-H. pylori activity (3.9 µg/mL) followed by P. anisum (15.63 µg/mL), while C. carvi showed the lowest activity (62.5 µg/mL). The in-silico study showed that cumaldehyde in C. cyminum has the best fitting energy to inhibit H. pylori.C. cyminum essential oil showed the maximum ability to reduce the production of Cox-2 expression approaching celecoxib with IC₅₀ = 1.8 ± 0.41 µg/mL, followed by the C. carvi oil IC₅₀ = 7.3 ± 0.35 µg/mL and then oil of P. anisum IC₅₀ = 10.7±0.63 µg/mL. The investigated phytochemicals in this study can be used as potential adjunct therapies with conventional antibiotics against H. pylori.
