Morphological characterization and chemical composition of Lubeg (Philippine Cherry)

Lubeg or Philippine Cherry is a fruit tree that grows on the west side of Luzon. It is abundant in the municipality of Lal-lo. This fruit tree has been declared as the municipal tree of the town and its by-products are registered as the official “One Town One Product” (OTOP). Its by-products are wine, candy, vinegar, jam and jelly. Lubeg tree remains to be not fully characterized especially the Lubeg trees that inhabit Lal-lo,Cagayan. Exploration of its morphology, classification and chemical composition are greatly considered. Thus, this study was conducted. Profiling and collection was done in the municipality of Lal-lo. The leaves were dried and extracted. Phytochemical analysis was conducted using tree solvents: aqueous, ethanol, and methanol using its leaves and fruits. Morphologically, lubeg tree is medium in size with a height of 5-7 meters. Its leaves have smooth leathery texture, simple, opposite, lanceolate, pinnately netted, entire and with acute apex. The flower is bisexual with white color and in cluster. Lubeg fruit is white to red to purple when ripe; is a berry fruit with brittle rind, ovoid and with one seed per fruit. Lubeg tree belongs to Family Myrtaceae under Phylum Magnoliophyta. The chemical composition of Lubeg leaves was high in steroids, tannins, and coumarins while its fruits was highly positive in quinones and flavonoids. It has anti-oxidant property, and anti-inflammatory. It can lower cholesterol level and reduce risks of heart disease.

Strategic bioprospecting of Ctenolepis garcinii for metabolic and infectious disease intervention using HPLC and GC-MS analysis

Diabetes mellitus, a common metabolic disorder, demands the development of safe and affordable therapeutic agents. Traditional medicinal plants provide valuable bioactive compounds with antidiabetic and antimicrobial potential. Ctenolepis garcinii, a climber from the Cucurbitaceae family used in South Indian and Sri Lankan medicine, remains scientifically underexplored. This study investigates its phytochemical composition and biological activities using phytochemical, chromatographic, antimicrobial, and molecular docking approaches, emphasizing its antidiabetic and antimicrobial efficacy. Ethanolic extracts of C. garcinii underwent qualitative and quantitative phytochemical screening, FTIR, UV–Vis, HPLC flavonoid profiling, GC-MS volatile compound identification, antimicrobial testing against Streptococcus aureus and Candida albicans, and molecular docking targeting SPA and Sky proteins. Phytochemical analysis revealed major constituents such as alkaloids (25.90%), flavonoids (21.50%), and phenols (18.40%). FTIR confirmed hydroxyl, aliphatic and aromatic hydrocarbons, ethers, halogens, and disulfides. UV–Vis analysis showed strong absorption at 353 nm and 407 nm, indicating phenolic and flavonoid presence. HPLC detected flavonoids including naringin (15.45 µg/mL), quercetin, kaempferol, and luteolin. GC–MS identified 20 compounds, notably tetracosanal (39.55%), 3-methylene-1-oxa-spiro[3,6]decane, and 3-methyl-2-(2-oxopropyl)furan. Antimicrobial assays showed moderate inhibition zones (8 mm for S. aureus, 7 mm for C. albicans). Docking studies revealed strong binding affinities of 3-methyl-2-(2-oxopropyl)furan with SPA (-7.4 kcal/mol) and Sky proteins (−8.3 kcal/mol). Overall, C. garcinii demonstrates a rich phytochemical profile with promising antidiabetic and antimicrobial potential. The identified compounds, supported by docking results, highlight its ethnomedicinal relevance and warrant further pharmacological and toxicological studies for drug development.

Phytochemical analysis and antibacterial activity of Biophytum sensitivum

World is rich in knowledge with a wide diversity of medicinal plants which provide people with traditional healing methods for diseases in general healthcare area. The agar diffusion method was used to examine the antibacterial activity of different solvent extracts of Biophytum sensitivum tested against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, and Staphylococcus aureus. For qualitative phytochemical investigation, several solvent extracts of the complete Biophytum sensitivum plant were investigated. The minimum inhibitory concentration (MIC) of Biophytum sensitivum ethanol extract had significant antimicrobial effectiveness against Escherichia coli (456 µg/ml), and Pseudomonas aeruginosa (419 µg/ml). The ethanolic extract showed (419 µg/ml and 398 µg/ml) antimicrobial activity against Klebsiella pneumonia and Staphylococcus aureus respectively. The lowest antibacterial activity was found in acetone extract with MIC (198µg/ml) of Biophytum sensitivum. Various parts of the plant has the presence of variety of phytoconstituents such as flavonoids, saponins, tannins, terpenes, steroids, amino acids, essential oil, polysaccharides and pectin.
