Essential Oils of Piper pendulispicum C. DC. and Piper hymenophyllum Miq.: Chemical Composition and Anti-microbial activity

Do Ngoc Dai et al.

Summary: Chemical compositions of essential oils from two Vietnamese Piper plants, Piper pendulispicum C. DC. and P. hymenophyllum Miq., were identified through hydro-distillation and GC-FID/MS analysis. The essential oils of P. pendulispicum leaf and stem were mainly composed of sesquiterpene hydrocarbons, with bicyclogermacrene and beta-caryophyllene as the principal compounds. P. hymenophyllum leaf oil was mainly composed of monoterpene hydrocarbons, with alpha-pinene and beta-pinene as the principal compounds. These essential oils exhibited better antimicrobial activity than the positive control streptomycin against three Gram-positive bacteria and comparable activity to cycloheximide against Candida albicans. Overall, the essential oil of P. pendulispicum showed greater potential for antimicrobial treatment than P. hymenophyllum leaf oil.

Chemical Composition and Preliminary Toxicity Evaluation of the Essential Oil from Peperomia circinnata Link var. circinnata. (Piperaceae) in Artemia salina Leach

Kessia do Socorro Miranda Mesquita et al.

Summary: Peperomia Ruiz and Pav, the second largest genus of the Piperaceae, was studied for seasonal and circadian variations in the chemical composition of its essential oils and aromas. The study found that the chemical composition is influenced by the period and time of collection. Clinical toxicity testing revealed that the essential oil extracted from dry material collected in July had the highest toxicity value.

Piper betle (L): Recent Review of Antibacterial and Antifungal Properties, Safety Profiles, and Commercial Applications

Ni Made Dwi Mara Widyani Nayaka et al.

Summary: Piper betle is a popular medicinal plant in Asia, with recent studies showing its potent antibacterial and antifungal properties. Extracts and essential oils from betel leaves can inhibit microbial growth, including multidrug-resistant strains, and display high efficacy against Gram-negative and Gram-positive bacteria as well as fungi. The combination of betel leaves with antibiotics has shown to enhance antibacterial properties, providing potential for the development of value-added products.
