“…Divergences may result from the environmental and phenological factors at play at the time of plant collection. Climate, seasons of the year, phenological stage, genetic load, temperature, altitude, cultivation conditions and humidity, among other factors, can significantly affect the quality and/or quantity of bioactive compounds (Szakiel, Pączkowski, & Henry, 2011;Pavarini, Pavarini, Niehues, & Lopes, 2012). In this context, this work aimed to investigate how seasonality, phenological stage, geographical location, plant cultivation substrate, and plant age influence the antimicrobial activity of Cochlospermum regium roots against the pathogenic microorganism Candida albicans.…”

ABSTRACT. Cochlospermum regium (Bixaceae) is a medicinal plant species native to the Brazilian savannah, known as the Cerrado. Local communities use its roots to treat infections of the female reproductive system. This study evaluated how seasonality, phenological stage, geographical location, plant age, and plant cultivation substrate affect the antimicrobial activity of Cochlospermum regium roots against Candida albicans. Although the plant displayed antimicrobial action in all the assayed conditions, the roots collected during fall and winter inhibited C. albicans the most effectively. The geographical location in which the plant material was found did not influence its biological response. Plant age and cultivation substrate did impact the biological response; those grown in sand showed fungicidal activity, while those grown in Cerrado soil fertilized with cow dung showed fungistatic activity during certain periods. The inner bark and core of the root were the main structures underlying the antimicrobial activity of Cochlospermum regium.

“…This assigns mangrove's noteworthy roles in the arena of natural product research and remedy detection since ancient times as crude or extracts or formulations [4], but plant reference chemicals possess a multifarious nature in their biochemical configurations, unknown chemical compositions and natural variability (quantitative and qualitative) allow them to differ noticeably and difficult to assess [5]. The specific environmental factors (like geography and place to place variations, physiology of the plant, its habitat, different soil composition and salinity levels, time of harvesting, levels of specific pollution and seasonal variations) and several other factors [5][6] found to be extremely influencing factors for phytoconstituents types and quantity existence in the plants [7][8]. The presence of other chemicals and impurities in the form of singularity or mixtures or multipart-motifs, also make it difficult to obtain a characteristic profile of a particular plant or its drug and also create many problems in standardisation of the drugs from the plant origin [9][10].…”

Objective: An attempt has been made to study phytoconstituents and High-Performance Thin Layer Chromatography (HPTLC) fingerprinting pattern of leaf/stem/root methanol extracts of Avicennia marina. Methods:The phytochemical screening was done by standard biochemical methods and standard optimized HPTLC densitometry determination was performed under two different energy zones [under UV-254 nm and under 540 nm after derivatization at sample size-10 µl, temperature = 25.8±0.3 °C (constant) and relative humidity = 86±1% (constant) in optimized solvent system].Results: Phytochemical analysis confirmed the presence of phytochemicals in the leaf, stem, and root of the plant. Under UV-254 nm energy range, the leaf, stem and root extract showed the presence of 8, 6 and 5 components respectively and under 540 nm energy zone after derivatization, the leaf, stem and root extract revealed the presence of 7, 5 and 5 components, respectively and specific marker components with very high concentration (under UV-254 nm; 3, 2, 2 in leaf, stem, and root respectively and under 540 nm after ASR treatment; 2, 1, 2 in leaf, stem, and root respectively) were detected among them. Conclusion:The preliminary phytochemical test results elucidated Avicennia marina leaf, stem, and root as a hug reservoir of various class of phytochemicals and metabolites. The results obtained by HPTLC fingerprinting method found to be acceptable as a quick, reliable, accurate and economical for identification and authentication of Avicennia marina mangrove plant and useful to differentiate this mangrove species from other similar mangroves, in a single TLC plate run. This serves as a biochemical marker pattern for leaf, stem and root parts of this mangrove and for its diverse phytoconstituents.

Se determinó la composición bromatológica de cáscara de banano (Musa paradisiaca) producida en Ecuador y se identificaron las fracciones y grupos fitoquímicos responsables de su actividad antimicrobiana. El análisis bromatológico determinó un porcentaje de humedad del 88,94% y 11,06% de sólidos totales (1,55% ceniza, 0,47% grasa, 0,74% proteína, 0,87% fibra y 8,3% carbohidratos totales). Para la obtención de las fracciones se aplicaron dos métodos de extracción por maceración. El primero usó cuatro solventes de diferente polaridad como éter de petróleo, cloroformo, acetato de etilo y agua. Los extractos obtenidos fueron sometidos a pruebas de tamizaje fitoquímico identificándose la presencia de compuestos grasos, esteroles, triterpenos, saponinas y taninos. El segundo método usó como solvente etanol al 70% y se generaron cinco fracciones. Ensayos de actividad antimicrobiana por el método de difusión en agar se realizaron en Staphylococcus aureus y Escherichia coli mediante el extracto crudo etanólico y sus fracciones, se evidenció actividad microbiológica. Ensayos de tamizaje fitoquímico y cromatografía en capa fina se realizaron sobre cada fracción y extracto identificándose los principales grupos de compuestos responsables de la actividad antimicrobiana.
