Neuropharmacological potential of various morphological parts of Camellia sinensis L.

Abstract

Camellia sinensis L. has long been used as a therapeutic agent for the Central nervous system (CNS) due to the presence of flavonoids. The present study aimed to evaluate the dose-dependent Neuropharmacological behavioral potential of Camellia sinensis seed and leaf extracts on mice. To evaluate the differential potential of leaf and seed extract various doses were prepared and examined in open field, head dip, rearing, cage cross, swimming and traction tests. One-way ANOVA set at P* < 0.05 followed by POST HOC LSD (P* < 0.01) was applied to evaluate the significant difference among the treatments. Herein both seed and leaf extract showed significant results at high doses. Interestingly leaf extract at high dose showed significant effect on mice CNS in open field and head dip test, while seed at high dose revealed significant stimulus on mice CNS in rearing, cage cross, swimming and traction tests. Overall results showed that seed produced more stimulant effect and less calmness as compared to leaf extract was. Tea leaves had already known as potential CNS stimulant drugs; current investigation suggests that tea seed can be used as an alternative CNS stimulant agent with more effective stimulant action.

Quality assurance and authentication of herbal drug (Argyrolobium roseum and Viola stocksii) through comparative light and scanning electron microscopy

“…Moreover, these plants should be further screened out for its molecular study, medicinal value, phytotoxic effects, pharmacological, antimicrobial potential, phytoremediation potential, and its association with other plants as well (Ashfaq et al, 2019a; Azam et al, 2020; Bahadur et al, 2020; Naeem et al, 2020; Rubab et al, 2020; Sajad et al, 2020; Sarah et al, 2019). The pollen characterization of Family Violaceae has been reported by various workers but a few studies are published on pollen morphology of Viola species using SEM and LM.…”

Palynological characteristics of selected Lamioideae taxa and its taxonomic significance

“…Sculpturing of Exine was observed as reticulate, microreticulate, and bireticulate, with colpus surface ornamentation verrucate, gemmate, scabrate, and psilate. These species further recommended for medicinal and pharmacological potential (Ashfaq et al, 2019; Bahadur et al, 2020; Zaman et al, 2020), macromorphological (Khan, Ahmad, Shuaib, Bahadur, & Hussain, 2020), nanoparticles (Azam, Ayaz, et al, 2020; Azam, Khan, et al, 2020), pharmacological, and antimicrobial potential (Rubab et al, 2020), ecological significance (Sajad, Khan, Bahadur, Naeem, et al, 2020; Sajad, Khan, Bahadur, Shuaib, et al, 2020), its association with other plants (Azam, Ayaz, et al, 2020; Azam, Khan, et al, 2020; Naeem et al, 2020; Sarah et al, 2019).…”

Foliar epidermal micromorphology and its taxonomic significance in Polygonatum (Asparagaceae) using scanning electron microscopy

“…In the last few decades, SEM has revolutionized bioscience and its various branches which provides the opportunity to explore consistent features to determine plant taxa, as well as information about the anatomical features such as leaf epidermal decoration, stomata type and distribution, epidermal cells, glandular, and non‐glandular trichomes, have proven to be the most useful traits in the identification and discriminations of the species of various plant groups (Nurit‐Silva & De Fátima Agra, 2011). Moreover, these plants should be further screened out for its medicinal value (Ashfaq et al, 2019b; Bahadur et al, 2020; Zaman et al, 2020), nanoparticles (Azam et al, 2020; Azam et al, 2020; Saqib et al, 2019), pharmacological and antimicrobial potential (Rubab et al, 2020), ecological significance (Retamales & Scharaschkin, 2015; Sajad et al, 2020), its association with other plants (Azam, Ayaz, et al, 2020; Azam, Khan, et al, 2020; Naeem et al, 2020; Sarah et al, 2019), and palynological using SEM (Amina et al, 2020; Ashfaq et al, 2018; Ayaz et al, 2020; Bahadur et al, 2018; Gul et al, 2019c; Naz et al, 2019; Sufyan et al, 2018) have been recommended to strengthen the taxonomy of Polygonatum .…”
