“…The macroscopic parameters of the fresh leaves including the type of leaf, shape, surfaces, venation, presence or absence of petiole, the apex, margin, base, lamina, and texture were noted. 8 The macroscopic pictures were obtained using a digital camera (Canon G11).…”

Introduction: The leaves of Polyscias guilfoylei L. (Araliaceae) were reported to have medicinal value. Therefore, authentication of the leaves of Polyscias guilfoylei L. is important to ensure the reproducible quality of herbal raw materials. Objective: This study aims to evaluate macroscopic and microscopic parameters of the leaves of Polyscias guilfoylei L. Methods: Organoleptic, macroscopy, and microscopy of fresh leaves and microscopy parameters of leaves powder were observed. Results: Organoleptic and macroscopic studies found that the leaves had a smooth surface with green color, pinnate venation, elonged to lanceolate shape, cuspidate apex, serrated margin, broad base steam, a bit of distinctive smell, and characteristic taste. The leaves microscopy indicated the presence of anisocytic and paracytic stomata, druses type of calcium oxalate crystals, spiral type xylem, and essential oil were found. Conclusion: The results obtained can be used as quality control parameters, especially diagnostic features for the herbal raw material of Polyscias guilfoylei L.

“…Some species contain antioxidant phenolic compounds, such as gallic acid, catechins, hydroxybenxoic acid, and coumaric acid. Also, the fruits of the species possess strong reducing properties and free radical scavenging properties with ABTS and DPPH assay which showed a significant relationship with phenolic and flavonoids content 45 .…”

In aerobic organisms, oxygen is essential for sufficient energy production but self-contradictory, produces chronic toxic stress in cells. So, protective techniques must exist for removal of toxic free radicals which are byproducts of oxygen. Diverse protective systems have evolved to enable adaptation of antioxidant activity. Tissues and organs have different rates of metabolic activity and oxygen consumption. Their levels of antioxidants are also different. Such is the case with glutathione (GSH) and cysteine, which are lower in the brain than the liver, kidney, or muscle. Investigations of oxidative responses in different complex organisms such as mammals, organs, and tissues which contain distinct antioxidant systems and this may form the basis for differential susceptibility to toxic agents. Notable advances have been made in our understanding of these distinct systems, with several antioxidant systems and their regulatory pathways being described at the cellular level, thus understanding the pathways leading to the induction of antioxidant responses will enable development of strategies to protect against oxidative damage.

“…Transverse sections of the leaf showed that the upper and lower epidermis consist of single-layered polygonal cells that cover the mucilaginous cuticle; vein islet and vein termination were 9–11 and 13–15, respectively [21,51]. Transverse sections of matured stem bark revealed multi-layered cork, made of rectangular, tangentially elongated, thin-walled cells, whereas the secondary cortex contained rectangular-polygonal parenchymatous cells with oval shaped starch grains [38,39,52,53,54].…”

“…For instance, tannins extracted from its bark are used as a dyeing agent [6]. Indeed, the presence of distinct bioactive compounds, such as alkaloids, flavonoids, glycosides, tannins, terpenoids, saponins, and volatile oils [8,21], has been increasingly reported as related to its pharmacological effects. For example, crude extracts and isolated compounds from M. esculenta exhibit both in vivo and in vitro pharmacological activities.…”

Myrica esculenta (Myricaceae) is a popular medicinal plant most commonly found in the sub-tropical Himalayas. It is widely used in folk medicine to treat several ailments such as asthma, cough, chronic bronchitis, ulcers, inflammation, anemia, fever, diarrhea, and ear, nose, and throat disorders. Due to its multidimensional pharmacological and therapeutic effects, it is well recognized in the ayurvedic pharmacopeia. However, the recent upsurge in M. esculenta use and demand has led to illicit harvesting by the horticultural trade and habitat loss, pushing the plant to the brink of extinction. Thus, the present review aims to provide updated information on M. esculenta botany, ethnomedicinal uses, phytochemistry, pharmacological effects, toxicity, and conservation methods, as well as also highlight prospective for future research. Particular emphasis is also given to its antioxidant potential in health promotion. In-depth literature was probed by searching several sources via online databases, texts, websites, and thesis. About 57 compounds were isolated and identified from M. esculenta, and the available reports on physicochemical parameters, nutritional and high-performance thin-layer chromatography analysis of bioactive plant parts are portrayed in a comparative manner. Friendly holistic conservation approaches offered by plant biotechnology applications, such as micropropagation, germplasm preservation, synthetic seed production, and hairy root technologies are also discussed. Nonetheless, further studies are needed to propose the mechanistic role of crude extracts and other bioactives, and even to explore the structure–function relationship of active components.
