Eucalyptus is a commonly planted tree in North India and its cultivation area is increasing. Leaves of Eucalyptus are used for tea which has healing properties and many other economic uses. Silicon is the second most abundant element in the earth’s crust next to oxygen. Silicon (Si) can improve photosynthesis, decrease transpiration, increase water use efficiency and provide resistance against biotic and abiotic stress. The clear information was not available regarding Silicon nourishment in tree species like Eucalyptus. Although a positive in plant development and overall dry matter production was noticed in Eucalyptus with Si application. The amount of nitrogen (N), phosphorus (P), and potassium (K) were inclined leaf whereas Calcium (Ca) and magnesium (Mg) content was not affected by Si application potassium silicate (K2SiO3). Finally results revealed that upon Si application significant increase in the leaf mineral content in almost all genotypes was recorded. Correlation studies revealed that leaf N and P were highly and significantly correlated with leaf copper (Cu) and iron (Fe) content, leaf Mg and leaf Cu were positively and significantly correlated with leaf N, manganese (Mn) and Fe content, leaf Mn and Fe content were highly and significantly correlated with leaf N, Mg and Cu content. To our detailed knowledge this is the first ever study conducted in Eucalyptus. Here the influence of potassium silicate on popular North Indian cultivars’ leaf mineral content Nevertheless, more studies are required to analyze the effect of Si application in tree species like Eucalyptus.

Background The plant Olax subscorpioidea Oliv (Olacaceae) is a shrub that is widely available in Africa. It has been used in traditional medicine to treat various diseases including asthma, pain, inflammation, gastrointestinal and central nervous system (CNS) disorders, cough, diabetes mellitus, cancer, infectious diseases, hepatic diseases, and many other diseases. Several phytochemical and pharmacological investigations were conducted on this plant. However, comprehensive information on this medicinally important plant is not available in the literature. Therefore, in this review, we aimed to provide comprehensive and critical information on all the reported ethnomedicinal uses, phytochemistry, pharmacological activities, and potential toxicity of Olax subscorpioidea to highlight its therapeutic potentials based on traditional usage and identify research gaps as a basis for further investigations to develop novel therapeutic compounds. Main body The available information about the plant was retrieved from the online bibliographic databases (PubMed and Google Scholar) and published PhD dissertation using the search terms Olax subscorpioidea, traditional uses, ethnomedicinal uses, phytochemistry, pharmacology, toxicology, and safety. Phytochemical studies have shown that the plant contains several bioactive compounds such as rutin, morin, quercetin, caffeic acid, santalbic acid, n-hexadecanoic acid, squalene, nonacosane, hentriacontane, and many more compounds. Also, pharmacological investigations revealed that Olax subscorpioidea has antidepressant, antiepileptic, anti-Alzheimer’s, cytotoxic, antioxidant, antihyperlipidemic, analgesic, antiinflammatory, antiarthritic, antidiabetic, anticancer, antiulcer, antimicrobial, hepatoprotective, apoptotic, antiprotease, and other CNS effects. Conclusion Several pharmacological studies on Olax subscorpioidea have established its ethnopharmacological uses. However, there are limited phytochemical and pharmacological studies to validate other folkloric claims of the plant. Therefore, extensive phytochemical and further pre-clinical efficacy and safety evaluations to fully establish its therapeutic potentials and elucidate its mechanisms of pharmacological actions could be necessary.

“…There are thousands of herbal plants in the world but the O. sanctum is considered to be the queen of herbs due to its greater medicinal values. Tulsi contains various phytochemicals, having strong antioxidant, antibacterial [46], antiviral, adaptogenic, and immune-enhancing properties that promote general health and support the body's natural defence against stress and diseases. Some of the main chemical constituents of tulsi are oleanolic acid, ursolic acid, rosmarinic acid, eugenol, carvacrol, Linalool, β-caryophyllene (about 8%), β-element (c.11.0%), and germacrene D (about 2%).…”

The antioxidant activities of four genotypes of basil species were selected for biochemical studies, viz., Ocimum sanctum L. (Rama Tulsi), Ocimum tenuiflorum L. (Krishna Tulsi), Ocimum gratissimum L. (Van Tulsi), and Ocimum basilicum L. (Babui Tulsi) for the antioxidant properties. Ocimum L. is considered useful in the treatment of respiratory system disorders, reduction of blood glucose level and is regarded as an 'adaptogen' or anti-stress agent. The phytochemical analysis of the plant leaves extract to the estimation of standard biochemical methods such as peroxidase, superoxide dismutase (SOD), polyphenol oxidase (PPO), catalase activity, antioxidant, flavonoids, total phenols, protein as well as total carbohydrates, starch and reducing and non-reducing sugar. The biochemical studies revealed that the starch (98 mg/gfw), the content was found to be higher in O. gratissimum. Similarly the other parameters such as total sugar (159 mg/gfw), non-reducing sugar (61mg/gfw), Peroxidase (142 U/mL), Catalase (188 U/mL), SOD (92.47 U/mL), PPO (462 U/mL) were found to be higher in O. sanctum. On the other hand, soluble protein (62 mg/gfw), total flavonoids (325 mg/gfw) and total flavonols (486 mg/gfw) were found to be higher in O. tenuiflorum. Total antioxidants (136.45 mg/gfw), reducing sugar (108 mg/gfw) and phenol (479 mg/gfw) were found to be higher in O. basilicum. The result shows that the best genotype among the four follows the trends O. sanctum > O. basilicum > O. tenuiflorum > O. gratissimum. On the basis of the result, the two genotypes can be recommended for medicinal purpose in the pharmaceutical application.
