Arbutus pavarii Pamp. (fam. Ericaceae), commonly known as “Shmeri” or “Libyan Strawberry”, is an endemic Libyan medicinal plant, currently considered as an endangered species of shrub or tree (Kabiel et al., 2016), and has attracted public attention in relation to its conservation. The distribution of this important forage species of plant for honeybees to produce specific honey type is considerably confined to the Al-Akhdar mountainous region in Libya.
pavarii Pamp。（Ericaceae家族），通常被称为“Shmeri”或“利比亚草莓”，是利比亚特有的药用植物，目前被认为是灌木或树木的濒危物种（Kabiel et al.，2016），并因其保护而引起公众关注。这种用于蜜蜂生产特定蜂蜜类型的重要饲料植物的分布在利比亚的Al-Akhdar山区相当有限。

The United Nation’s New Urban Agenda has created a playbook for planning advocates. It opens possibilities for building inclusive, integrated urban planning in countries where planning has been top-down and limited in scope. Yet it raises concerns about ignoring the power of industry and imposition of global ideas inappropriate to national contexts. Success will require strengthened capacity building for the urban professions, and sensitivity in adapting global best practices to national contexts.

Plant pathogens lead to severe damage of the agricultural crops, worldwide. The disease management is currently being done by the synthetic chemicals. In the present report, Cinnamomum tamala (Buch.-Ham.) T. Nees & Eberm. oil was analyzed by gas chromatography-FID and GC/MS, which revealed (E)-cinnamaldehyde (40.6%), (E)-cinnamyl acetate (19.6%), linalool (10.2%) and benzaldehyde (3.6%) as marker constituents. Contact, volatile and spore germination inhibition assays were performed to determine the antifungal activities of Cinnamomum tamala (Buch.-Ham.) T.Nees & Eberm. against Rhizoctonia solani AG 4, Choanephora cucurbitarum and Bipolaris australiensis. C. tamala oil 500-560 ppm showed complete fungal growth inhibition in poison food technique over concentration range of. Solid-phase microextraction analysis of drop diffusion assay revealed the presence of benzaldehyde in headspace of Petri-plate, and found to be one of the strongest antifungal compounds against tested phytopathogens. Similarly, an oil concentration of 500 ppm inhibits spore germination. Therefore, products containing such compositions can be used for the plant diseases management.

This study was designed to evaluate and compare the phytochemical constituents along with the bioactivities of Solanum khasianum C.B. Clarke. leaves (SKLME) and berries (SKBME) methanolic extracts. Alkaloids, flavonoids, saponins, steroids, terpenoids, phenols, oxalates and cardiac glycosides were present in SKLME and SKBME. Considerable amounts of phenolic and flavonoids were found in SKLME and SKBME. SKBME showed better antioxidant activity with an IC50 value of 20.68 μg/mL vs SKLME (38.30 μg/mL). SKBME and SKLME respectively showed anti-inflammatory activity with IC50 of 20.96 and 23.37 μg/mL. Apart from this, the present investigation also reports SKBME skin whitening ability, anti-diabetic potential and anti-cholinesterase activity with IC50 values of 33.97, 28.24, and 32.42 μg/mL, respectively. Furthermore, SKLME showed herbicidal property with a total germination rate of 9.06% at a concentration of 80 μg/mL. Bioactivity analysis revealed higher pharmacological importance of the SKBME than SKLME, as well.

Some of the isolated compounds (3, 4 and 5) were tested in vitro against bacteria strains Escherichia coli, Bacillus subtilis, Pseudomonas agarici, and Micrococcus luteus. Compound 3 displayed good activity against Bacillus subtilis, Micrococcus luteus, and Pseudomonas agarici with MIC values of 1.7, 2.3 and 9.8µM, respectively; while compound 4 showed significant activity against Micrococcus luteus with MIC value of 11.9µM.

This study divulges a comparative analysis of Berberis tinctoria Lesch. leaf, stem, and fruit towards proximate contents assessment, e.g., moisture, crude-ash, crude-fibre, crude-lipid, crude-protein, nitrogen-free extract, energy followed by ICP-MS analysis which revealed that fruits have a higher amount of essential minerals. The primary metabolites were higher in the fruit extract, whereas more secondary metabolites were observed in the methanolic extracts in the hierarchy of leaf and fruit then stem, respectively. Likewise, a higher amount of antioxidant activities were observed in ethyl acetate and methanolic extracts. The fruit ethyl acetate extract showed a maximum of 95.27% anti-inflammatory activity. The fruit methanolic extract exhibited an antidiabetic activity with IC50 values of 75.5 ± 6.8 μg/mL and 45.4 ± 11.1 μg/mL for α-amylase and α-glucosidase, respectively. A significantly positive correlation was identified between the secondary metabolites and antioxidant activities. The principal component analysis implies ethyl acetate and methanolic extracts as pivotal extracts of B. tinctoria.
