Background: Garcinia daedalanthera is an Indonesian plant where commonly found in Sulawesi, Indonesia and spread out in the forest. Garcinia daedalanthera is one of Clusiaceae family that have been scientifically proven to provideantidiabetic and antioxidant activity but never been examined in pharmacognosy parameters. Pharmacognostical parameters of the leaves were studied with the aim of drawing the pharmacopoeial standards for this species. Methods: The present study was aimed to analysis the pharmacognosy of Garcinia daedalanthera including leaf morphology, microscopic characteristics, physicochemical parameters, phytochemical study, contaminant analysis and FTIR spectrum analysis. Results: The phytochemical analysis revealed the presence of flavonoids, saponins, tannin, steroids and phenols.The moisture content was 2.35%, total ash 2.51%, acid insoluble ash 0.05%, total flavonoid and phenolic content were found to be 3.121% and 14.36% (w/w). The level of Arsenic (As), Cadmium (Cd) and lead (Pb) were found under the limit (0.357 ppm) and the extract of

RESUMOPiper arboreum Aubl. var. arboreum e P. tuberculatum Jacq. (Piperaceae), conhecidas como pimenta-longa, são comercializadas como produtos tradicionais fitoterápicos e, frequentemente, identificadas erroneamente, não havendo relatos sobre controle de qualidade dessas espécies. O objetivo do trabalho foi preparar e caracterizar drogas vegetais foliares e caulinares dessas espécies para estabelecer-lhes parâmetros de autenticidade botânica e grau de pureza para o controle de qualidade. Foram utilizados métodos padrões para o preparo e análises estrutural e físico-química das drogas vegetais. São caracteres diagnósticos macroscópicos para distinguir as drogas vegetais íntegras: tamanho, forma, cor, sabor, textura, características da superfície de fratura e da secção transversal e os padrões de venação foliar. São caracteres diagnósticos para distinguir as drogas vegetais pulverizadas: padrões de cutícula e cera epicuticular, tipos de tricoma e espessamento parietal dos elementos traqueais e a forma do hilo dos grãos de amido. Emergências são marcadores morfológicos chave para as drogas vegetais de P. tuberculatum. Os valores dos parâmetros físico-químicos foram similares nas drogas vegetais das espécies, exceto o de cinzas ácido-insolúveis que foi maior nas drogas vegetais caulinares de P. arboreum var. arboreum. As maiores concentrações de metais ocorreram nas drogas vegetais de P. arboreum var. arboreum. As concentrações mais elevadas foram de Al, Cu, Mn e V e as mais baixas de Cd, Co e Hg. Os resultados obtidos poderão ser utilizados como parâmetros de controle de qualidade para as drogas vegetais de ambas as espécies. PALAVRAS-CHAVE: Pimenta-longa, Produtos tradicionais fitoterápicos, Farmacognosia, Metais tóxicos, ICP-OES. Pharmacognostical characterization of Piper arboreum var. arboreum and P. tuberculatum (Piperaceae)ABSTRACT Piper arboreum Aubl. var. arboreum and P. tuberculatum Jacq. (Piperaceae), both known as "pimenta-longa", are frequently misidentified. Despite the fact that both species are sold as traditional phytotherapeutic products, there are no reports on their quality control. The aim of this study was to prepare and characterize leaf and stem herbal drugs of both species using standard methods aiming to establish parameters for botanical authentication and purity degree for their quality control. Size, shape, color, taste, texture, fracture surface and transection characteristics, and leaf venation patterns are macroscopic diagnostic characters useful to distinguish the herbal drugs when they are not powdered. The following characters are useful for diagnostic purposes of the powdered herbal drugs: cuticular and epicuticular wax patterns, types of trichomes, and wall thickening of the tracheary elements, and shape of the hilum of the starch grains. Emergences are key morphological markers for P. tuberculatum herbal drugs. Physicochemical parameter values were similar in herbal drugs of both species, except acid-insoluble ash value which was higher in the P. arboreum var. arboreum stem her...

“…The essential oil of Pyrrosia species contained bioactive constituents such as triterpenoids, hydrocarbons, alcohols, and phenols, which was similar to the previous reports. [5,12,13] The study of Cui et al showed that differences in volatile oil between Pyrrosia species significantly affected the quality of the medicinal substances. [14] It is notable that the chemical components and content of trans,trans-2,4-heptadienal, hotrienol and trans,cis-2,4-decadienal in volatile oils from Pyrrosia samples were quite different.…”

The present study was aimed at analyzing the chemical components of the essential oil from six Pyrrosia species by GC/MS and evaluating their in vitro antibacterial activities. Seventy volatile compounds were identified in the essential oil of six Pyrrosia samples. The identified volatile components were divided into following nine categories: aldehydes, terpenoids, fatty acids, ketones, furans, hydrocarbons, alcohols, esters, and phenols. The major components of the essential oil were 2,4-pentadienal, phytol and nonanal. The antimicrobial assays showed that the essential oils from Pyrrosia samples exhibited a broad-spectrum antimicrobial activity. However, P. lingua had the highest antibacterial activity against Staphylococcus aureus (ATCC 25923) with a minimum inhibitory concentration (MIC) of 2.5 μL/mL. This article is the first report of the chemical components and antimicrobial activity of the essential oil from six Pyrrosia species, which will lay the foundation for developing medicinal resources from Pyrrosia fronds.
