The comprehensive identification of phenolic compounds in food and beverages is a crucial starting point for assessing their biological, nutritional, and technological properties. Pomegranate (Punica granatum L.) has been described as a rich source of (poly)phenolic components, with a broad array of different structures (phenolic acids, flavonoids, and hydrolyzable tannins) and a quick, high throughput, and accurate screening of its complete profile is still lacking. In the present work, a method for UHPLC separation and linear ion trap mass spectrometric (MSn) characterization of pomegranate juice phenolic fraction was optimized by comparing several different analytical conditions. The best solutions for phenolic acids, anthocyanins, flavonoids, and ellagitannins have been delineated and more than 70 compounds have been identified and fully characterized in less than one hour total analysis time. Twenty-one compounds were tentatively detected for the first time in pomegranate juice. The proposed fingerprinting approach could be easily translated to other plant derived food extracts and beverages containing a wide array of phytochemical compounds.

During a previous study that identified plants used in traditional medicine in Togo to treat infectious diseases, Daniellia oliveri was specifically reported to treat intertrigo and candidiasis. Consequently, to explore the anti-infective potential of this plant, we investigated the antibacterial and the antifungal activity of the plant’s parts, as well as the cytotoxic activities of raw extracts and subsequent fractions, and the chemical composition of the most active fractions. In order to evaluate the antimicrobial activity, MICs were determined using the broth dilution method. Then, the most active fractions were evaluated for cytotoxicity by using normal human cells (MRC-5 cells) via the MTT assay. Finally, the most active and not toxic fractions were phytochemically investigated by GC-MS. Interestingly, all the raw extracts and fractions were active against the bacteria tested, with MICs ranging from 16 µg/mL to 256 µg/mL, while no antifungal activity was observed at 256 µg/mL, the highest tested concentration. Moreover, no toxicity was observed with most of the active fractions. The subsequent chemical investigation of the most interesting fractions led to identifying terpenes, phytosterols, phenolic compounds, and fatty acids as the main compounds. In conclusion, this study demonstrated that D. oliveri possesses valuable antibacterial activities in accordance with traditional use.

Background Costus speciosus, Cymbopogon citratus, and Tabernaemontana coronaria are herbal plants traditionally used as remedies for symptoms of tuberculosis (TB) including cough. The aims of the present study were to evaluate the in vitro anti-TB activity of different solvent partitions of these plants, to identify the phytochemical compounds, and to assess the effects of the most active partitions on the growth kinetics and cellular integrity of the tubercle organism. Methods The in vitro anti-TB activity of different solvent partitions of the plant materials was determined against M. tuberculosis H37Rv using a tetrazolium colorimetric microdilution assay. The phytochemical compounds in the most active partition of each plant were identified using gas chromatography-mass spectrometry (GC-MS) analysis. The effects of these partitions on the growth kinetics of the mycobacteria were evaluated over 7-day treatment period in a batch culture system. Their effects on the mycobacterial cellular integrity were observed under a scanning electron microscope (SEM). Results The respective n-hexane partition of C. speciosus, C. citratus, and T. coronaria exhibited the highest anti-TB activity with minimum inhibitory concentrations (MICs) of 100–200 μg/mL and minimum bactericidal concentration (MBC) of 200 μg/mL. GC-MS phytochemical analysis of these active partitions revealed that majority of the identified compounds belonged to lipophilic fatty acid groups. The active partitions of C. speciosus and T. coronaria exhibited high cidal activity in relation to time, killing more than 99% of the cell population. SEM observations showed that these active plant partitions caused multiple structural changes indicating massive cellular damages. Conclusions The n-hexane partition of the plant materials exhibited promising in vitro anti-TB activity against M. tuberculosis H37Rv. Their anti-TB activity was supported by their destructive effects on the integrity of the mycobacterial cellular structure.

Aquilaria Species (Thymelaeaceae) Distribution, Volatile and Non-Volatile Phytochemicals, Pharmacological Uses, Agarwood Grading System, and Induction Methods
2021
Agarwood is a highly valuable fragrant wood of Aquilaria spp. (Thymelaeaceae) which has been widely utilized in traditional medicine, religious rites, and cultural activities. This study summarizes a review on the identification of Aquilaria cultivars, volatile and non-volatile phytochemicals, pharmacological uses, and agarwood grading system to determine its quality, and different agarwood induction methods. Due to the highly demanding and depleted natural resources, the research on agarwood is still insufficient, and it has broad research and development prospects in many industries. However, due to the significant scientific nature of agarwood application, developing high-quality products and drugs from agarwood have become highly important, while no one has discussed in detail the phytochemicals uses and provided a summary until now. The main phytochemicals of agarwood include terpenoids, dominated by sesquiterpenes. For centuries, terpenoids have been used in traditional Chinese medicine and have been shown to possess various pharmacological properties, including bacteriostatic, antibacterial, sedation, analgesia, anti-inflammation, anti-asthmatic, hypoglycemic, antidepressant, and many others. Alongside biological activity screening, phytochemical advances and pharmacological research have also made certain progress. Therefore, this review discusses the research progress of agarwood in recent years and provides a reference basis for further study of Aquilaria plants and agarwood.

Salvia schimperi is widely used in Ethiopian folk medicine, particularly its raw and roasted seeds for treating ailments such as diarrhea. While numerous reports on its traditional uses and biological activities exist, limited chemical datasets are available on this plant. This study aimed to annotate and identify the phytochemical constituents in S. schimperi seed extracts. The ground samples of S. schimperi seeds (raw and roasted) were extracted with 80% methanol prior to metabolomic analysis using LCMS. Data processing and compound identification were conducted using MZmine, SIRIUS and XCMS platforms. Multivariate statistical analyses and biological targets prediction were carried out via XCMS, MetaboAnalyst, BindingDB and Therapeutic Target Databases. Annotation by SIRIUS based on ZODIAC, SIRIUS and confidence scores criteria, validated 99 of the 689 identified compounds. Among the compounds annotated by METLIN in XCMS, 105 were predicted to be of significant value based on multivariate analysis of MetaboAnalyst. Compounds annotated comprised of primary and secondary metabolites. Two alkaloid compounds (actinonin and indole acrylate) were identified as significant from SIRIUS and METLIN/MetaboAnalyst, with actinonin described as a potent antibacterial metabolite. To our knowledge, this study represents the first metabolomic fingerprinting of S. schimperi seed extracts, revealing diverse bioactive phytochemicals with nutritional and therapeutic potential. The consistent identification of actinonin suggests promising antibacterial applications. Roasting significantly alters the metabolite profile, reducing certain nutritional components such as isoleucine. These findings underline the importance of processing methods in determining phytochemical composition and bioactivity. Further research would explore the toxicity and potential functional food applications.

Cancer is a hard-to-treat disease with a high reoccurrence rate that affects health and lives globally. The condition has a high occurrence rate and is the second leading cause of mortality after cardiovascular disorders. Increased research and more profound knowledge of the mechanisms contributing to the disease’s onset and progression have led to drug discovery and development. Various drugs are on the market against cancer; however, the drugs face challenges of chemoresistance. The other major problem is the side effects of these drugs. Therefore, using complementary and additional medicines from natural sources is the best strategy to overcome these issues. The naturally occurring phytochemicals are a vast source of novel drugs against various ailments. The modes of action by which phytochemicals show their anti-cancer effects can be the induction of apoptosis, the onset of cell cycle arrest, kinase inhibition, and the blocking of carcinogens. This review aims to describe different phytochemicals, their classification, the role of phytochemicals as anti-cancer agents, the mode of action of phytochemicals, and their role in various types of cancer.

This study investigated the chemical and biological potential of Bidens pilosa and Croton sp., plants from megadiverse ecosystems in Colombia, collected in Santander de Quilichao (Cauca) and San Basilio de Palenque (Bolivar). The chemical profile was analyzed by UHPLC-ESI-Orbitrap-HRMS, and the total phenolic and flavonoid content was quantified using colorimetric methods. Antioxidant capacity was assessed using methods that evaluate reducing power and electron transfer mechanisms. The inhibition of key enzymes in skin aging, such as tyrosinase, hyaluronidase, and collagenase, was evaluated, as well as cytotoxicity in keratinocytes and human melanoma cells. Chemical characterization revealed distinctive phytochemical profiles: B. pilosa contained 21.1 mg GAE/g DT of phenolics and 64.6 mg RE/g DT of flavonoids, dominated by p -coumaric acid and rosmarinic acid, while Croton sp. exhibited higher levels of phenolics (169.4 mg GAE/g DT) and 54.1 mg RE/g DT of flavonoids, highlighting rosmarinic acid, p -coumaric acid and quercetin. Both extracts showed significant antioxidant capacity and enzyme modulation, including moderate collagenase inhibition (53.9–55.0%), high hyaluronidase inhibition (64.5–76.5%), and low tyrosinase inhibition (11.1–12.7%), suggesting protection of extracellular matrix and hyaluronic acid during skin aging. Sun protection factor was limited (SPF: 14.5 for B. pilosa and 11.6 for Croton sp.), with low ultraviolet absorption, consistent with low antityrosinase activity. Cytotoxicity assays demonstrated that B. pilosa was not toxic to HaCaT keratinocytes (IC₅₀ > 500 µg/mL) and displayed antimelanoma activity on A375 cells (IC₅₀ = 398.6 µg/mL), whereas Croton sp. showed moderate selectivity towards melanoma cells (IC₅₀ HaCaT = 329.5 µg/mL; IC₅₀ A375 = 189.0 µg/mL). The results suggest that both plants have potential in dermatological applications such as anti-melanoma agents, antioxidants, and modulators of skin aging enzymes, although highlight the importance of improving strategies to maximize their efficacy and safety.

2024
The fruit of Choerospondias axillaris (Anacardiaceae), known as south wild jujube in China, has been consumed widely in several regions of the world to produce fruit pastille and leathers, juice, jam, and candy. A comprehensive chemical study on the fresh fruits led to the isolation and identification of 18 compounds, including 7 new (1 –7 ) and 11 known (8 –18 ) comprised of 5 alkenyl (cyclohexenols and cyclohexenones) derivatives (1 –5 ), 3 benzofuran derivatives (6 –8 ), 6 flavonoids (9 –14 ) and 4 lignans (15 –18 ). Their structures were elucidated by extensive spectroscopic analysis. The known lignans 15 –18 were isolated from the genus Choerospondias for the first time. Most of the isolates exhibited significant inhibitory activity on α -glucosidase with IC[sub.50] values from 2.26 ± 0.06 to 43.9 ± 0.96 μM. Molecular docking experiments strongly supported the potent α -glucosidase inhibitory activity. The results indicated that C. axillaris fruits could be an excellent source of functional foods that acquire potential hypoglycemic bioactive components.
