Abstract. Shabira AP, Tjahjoleksono A, Lestari Y. 2022. Endophytic actinobacteria of Eleutherine palmifolia as antioxidant producer. Biodiversitas 23: 4209-4215. can generate bioactive compounds similar to those produced by the host plant. The (L.) Merr is an example a widely utilized plant in Dayak community. Flavonoids, which have effects, are among found E. palmifolia. activity endophytic re...

Bioautography has been used as rapid and easy strategy to detect and identify bioactive fractions/molecules in the never before investigated Hedyosmum sprucei Solms (Chloranthaceae) essential oil (EO). The antioxidant activity, performed through DPPH bioautographic assay and spectrophotometric evaluations (IC50 = 230 ± 10 µg/mL), seemed to be mainly due to α-cadinol and α-muurolol. (HP)TLC bioa...

BACKGROUND Olea africana leaves are used by Bapedi people to treat different ailments. The use of these leaves is not validated, therefore the aim of this study is to validate antimicrobial properties of this plant. METHODS The ground leaves were extracted using solvents of varying polarity (hexane, chloroform, dichloromethane (DCM), ethyl acetate, acetone, ethanol, methanol, butanol and wate...

PURPOSE Coleus amboinicus is a medicinal plant traditionally used to treat various diseases such as throat infection, cough and fever, diarrhea, nasal congestion and digestive problems. The plant was explored for endophytic fungi producing antimicrobial agents. METHODS Screening for endophytic fungi producing antimicrobial agents was conducted using agar plug method and antimicrobial activity...

Salvia genus is one of the largest genera of the Lamiaceae family. Its species have been used for a wide variety of disorders in the local traditional medicine systems. Therefore, the genus has been the subject of several phytochemical and biological studies. The aim of the study was to identify the major antioxidant compound(s) from the methanol extract of Salvia verticillata using activity-gu...

Objective: The objective of the study was to carry out phytochemical profiling essential oils (EOs) and evaluation their anti-microbial activity. Methods: EOs extracted from Cumminum cyminum, Zingiber officinale, Trachyspermum ammi, Alipnia galanga, Cedrus deodara, Elettaria cardamomum using clavenger apparatus. Phytochemical analysis high-performance thin layer chromatography (HPTLC) fingerpri...

Solvent extracts from the carnivorous plant Dionaea muscipula (Venus flytrap) were prepared using eight different organic solvents, and examined for antibacterial activity against food-related pathogenic and putrefactive bacteria. All solvent extracts showed higher antibacterial activity against gram positive bacteria than against gram negative bacteria. The TLC-bioautography analysis of the ex...

S treptococcus mutans (Gram-positive) and higella dysenteriae (Gram-negative) are two types of pathogen bacteria. The use synthetic antibiotics against both bacteria is known to impact the bacteria's resistance. E. spinosum from Tasikmalaya a potential macroalgae as source an antibacterial compound for research aims determine metabolite s pinosum originated S. . was conducted through several st...

The richness of bioactive compounds in plant materials encourages continuous development of separation methods and bioassays for their isolation and identification. Thin-layer chromatography-direct bioautography links separation on the adsorbent layer with biological tests performed directly on it. Therefore, the method is very convenient for searching plant constituents with biological activit...

AIM The aim was to screen the selected Indian plants for their antibacterial efficacy against four cariogenic bacteria Lactobacillus acidophilus (LA)(Microbial Type Culture Collection [MTCC]-*447), Lactobacillus casei (LC) (MTCC-1423), Streptococcus mutans (SMU) (MTCC-890) and Staphylococcus aureus (MTCC-96). To identify and characterize active principle present in these plants for the treatmen...
