Background: The use of herbs as traditional medicine in Indonesia is increasing, with more than 40% of Indonesia's population utilizing them. White oyster mushroom (Pleurotus Ostreatus) is a fungus that has various therapeutic effects including antioxidant, anti-inflammatory, anti-bacterial, anti-cholesterol, and anti-cancer properties. This mushroom contains many active substances in its secondary metabolites which have pharmacological effects. The purpose of this study was to identify the active compounds in the ethanolic extract of white oyster mushroom that will form the extract profile and become the basis for drug development. Methods: The active compound test used High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography with Mass Spectrometer (LC-MS). Ethanolic extract of white oyster mushroom was processed by 70% alcohol maceration, evaporation, and thickening. Results: The results of the HPLC test showed that the ethanolic extract of white oyster mushroom contained cinnamic acid and rutin, while the LC-MS test showed the presence of p-coumaric acid, Ascorbic acid, Linoleic acid, 9-Eicosene (E), Niacinamide, Veritric acid, Syringic acid, Ergosterol. Conclusions: The active compounds that were detected in the ethanolic extract of white oyster mushroom showed that the extract had the potential for antioxidant and anti-inflammatory activity.

The discovery of new active compounds of natural products tends to be increasingly more challenging due to chemical complexity and unpredictable matrices. Forskolin is an active natural labdane-type diterpenoid ingredient widely used worldwide for the treatment of glaucoma, heart failure, hypertension, diabetes, and asthma, and is expected to be a promising anticancer, anti-inflammation, and anti-HIV agent. In recent years, demand for forskolin in the medicine market has increased dramatically. However, natural forskolin originates exclusively from traditional Indian herb medicine Coleus forskohlii (Willd.) Briq. In a previous study, we isolated a series of diterpenoids including an 8,13-epoxy-14ene labdane carbon skeleton from Blumea aromatica DC. In order to identify alternative plant resources, a novel and effective strategy was proposed for the screening of potential forskolin-type diterpenoids (FSKD) compounds obtained from B. aromatica, using the mass defect filtering (MDF) strategy via ultra-high-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS) approach. Within a narrow, well-defined mass defect range, the strategy developed could significantly improve the detection efficiency of selected FSKD compounds by filtering out certain major or moderate interference compounds. Additionally, the MS/MS cleavage behavior and the characteristic diagnostic ions of the FSKD compounds were proposed to be used in aiding structural identification of the filtration compounds. As a result, a total of 38 FSKD of B. aromatica were filtered out and tentatively identified. To the best of our knowledge, it was the first time that these forskolin-type diterpenoids were identified in B. aromatica, which significantly expands our understanding of the chemical constituents of Blumea species, and allows B. aromatica to be used as a potential alternative plant resource that contains these forskolin-type active compounds. The strategy proposed was proven efficient and reliable for the discovery of novel compounds of herbal extracts.

Abstract Embelia ribes is a traditional Chinese medicine compound used as a remedy for various diseases. Nevertheless, detailed information regarding its chemical composition is unavailable. Herein, ultra-high-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry was used to characterize the components of E. ribes. A total of 56 compounds, including 16 phenolics, 16 flavonoids, 4 coumarins, 5 fatty acids and 15 other compounds were identified. Furthermore, the total phenolic and total flavonoid content was also assessed; the acetic ether extract of E. ribes was an ideal source of phenolics (308.16 ± 0.00 mg gallic acid equivalents/g of extract) and flavonoids (62.00 ± 0.01 mg rutin equivalents/g of extract). Additionally, acetic ether extract exhibited a high antioxidation effect (ferric reducing activity power: 0.15 ± 0.01 mg/mL; 1,1-diphenyl-2-picrylhydrazyl: 0.18 ± 0.01 mg/mL; 2,2-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid: 0.06 ± 0.01 mg/mL). Further, the nitric oxide concentration in lipopolysaccharide-simulated macrophage RAW 264.7 cells and the pro-inflammatory cytokines (TNF-α and IL-6) were suppressed by acetic ether extract. These findings support the notion that E. ribes is an ideal antioxidant and anti-inflammatory agent.
