“…The production and activity of bioactive compounds are influenced by genetics and the environmental factors surrounding the habitat [ 7,8 ]. Different agro-climatic conditions have been reported to have effects on the alkaloids, phenols, flavonoids, saponins, terpenes, total phenolic contents and antioxidant potential of Aloe Vera plant [5 ]. Improvement in soil fertility through application of organic amendment has been shown to increase the water content and the maturity stage of the leaves, thus contributing to a reduction in the content of total and individual glucosinolates as well as flavonoids and anthocyanins [29].…”

“…Several factors such as age, cultural practices, environment, the season and the varieties have been reported to influence the nutrient composition of plants [ 34 ]. Factors such as pH, available nutrients, texture, organic matter content, soil water relationship, weather and climate factors among others have been reported to directly or indirectly affect the nutritional quality of plants [5]. In addition, soil pH and organic matter affect plant nutrient availability and soil functions.…”

“…Environmental disturbances resulting from mining and road construction activities also contribute to changes in soil quality [ 3 ], and in consequence affect the elemental composition in plants [4 ]. Climatic change has been reported to have a great influence on the life cycle, distribution and phytochemical composition of the world's vegetation [5 ]. Phytochemical composition of medicinal plants is known to be affected by a number of environmental factors such as altitude, soil type and change of season [ 6,7,8 ].…”

Background: Polyscias fruticosa is used widely as food, remedy for diseases, and as an ornamental across Afro-Asian countries. For instance, P. fruticosa is used traditionally as an anti-asthma, anti-tussive, and a muco-suppressant herbal remedy for asthmatics in Ghana. Although many studies have investigated the pharmacological basis of the ethnobotanical uses of P. fruticosa, however, its effect on the reproductive system remains completely unknown. Aim of study: This study assessed effects of P. fruticosa leaf extract (PFE) on male fertility and toxicity in adult male Wistar rats. Materials and methods: After crude preparation of PFE, it was subjected to qualitative phytochemical, thin layer chromatography and gas chromatography mass spectrometry analyses. The effect of PFE was assessed on male fertility and toxicity by using healthy adult male Wistar rats. Rats were randomly assigned to normal saline (5 ml/kg po, n = 5), Clomiphene Citrate (CL; 50 mg/kg po; n = 5), and PFE (100, 200, and 500 mg/kg po; n = 5, respectively) groups and treated for 21 days. On day 22, rats were sacrificed and male fertility parameters (left testis weight, relative testis weight, caudal epididymal weight, caudal epididymal sperm count, sperm motility, sperm morphology, and assessment of male sex hormones and testicular histology) were assessed. Results: There were no significant changes in bodyweight, weight of left testis, weights of right and left caudal epididymides between treatment groups (PFE and CL) and control. Caudal epididymal sperm count increased in PFE (100 and 500 mg/kg)-treated rats relative to control. Sperm motility relatively increased in PFE-treated rats compared to control. Sperm abnormality decreased in PFE-treated rats, especially in PFE (100 mg/kg) group compared to control. Serum testosterone levels decreased inversely with serum luteinizing hormone levels in PFE-treated rats compared to control. There were minimal-to-no-alterations in histological sections of testis, except vacuolations at primary spermatocyte stage. Glycosides, saponins, cyanogenic glycosides, sterols, and alkaloids were detected in PFE. Conclusion: PFE improved caudal epididymal sperm count and may be useful as male fertility enhancer but exhaustive safety studies on key male sex organs needs to be established.

“…El estudio presenta algunas limitaciones, por ejemplo, el análisis de la capacidad antioxidante fue limitado, debido a que podrían haberse usado pruebas de mayor complejidad como el scavenging con H 2 O 2 , la actividad quelante de metales, sistemas de ácido linoleico, entre otros; que hubieran permitido caracterizar mejor la actividad antioxidante encontrada (30) . …”

Objetivo: Determinar la actividad antioxidante en partes aéreas (hojas, tallos y flores) de la especie Loricaria ferruginea Ruiz & Pav. Wedd. Material y Método: El material vegetal fue recolectado en la quebrada de Llaca, Provincia de Huaraz, Región Ancash. Los extractos se obtuvieron utilizando el método de extracción sólido - líquido Soxhlet con etanol. El extracto etanólico fue fraccionado utilizando solventes de polaridad creciente. Para la determinación de la actividad antioxidante se utilizó el método de neutralización del radical libre Difenildipicrilhidracil (DPPH). Se determinó la Concentración Efectiva Media (CE50) en la fracción de mayor actividad. Asimismo se realizó el tamizaje fitoquímico preliminar, para determinar los tipos de metabolitos secundarios presentes en la planta. En el extracto etanólico total y sus fracciones también se realizó un análisis fitoquímico preliminar con el mismo objetivo. Resultados: La fracción de acetato de etilo tuvo mayor actividad antioxidante 19.25% (10 μg/mL) y 73.47 % (50 μg/mL), con una CE50 de 28.37μg/mL. El tamizaje fitoquímico de la especie vegetal, indicó la presencia de flavonoides, triterpenos y catequinas. El análisis fitoquímico preliminar en la fracción Acetato de Etilo detectó la presencia de flavonoides y catequinas. Conclusión: La fracción de acetato de etilo tuvo mayor actividad antioxidante, pero inferior a la sustancia patrón (Rutina), pudiendo los flavonoides y catequinas estar relacionados con la actividad antioxidante.
