“…Many Heliotropium plants are mainly found being spread in tropical Asia, Africa, Australia, Europe, and Northern America (Gottschling & Hilger, 2004;Miller, 2003;Retief & Van Wyk, 2001). The bark, leaf juice, leaves, roots, seeds, stems, twigs and whole plant parts of Heliotropium are used as aphrodisiac, laxative, ethnoveterinary medicines, as traditional medicines, for ulcers and headaches, in treatment for schizophrenia, absorption of calcium, muscle protein, post-surgery recovery, sports injuries (Maroyi, 2021;Tidke et al, 2021).…”

The medicinal value of medicinal plants lies in some bioactive constituents that produce a definite physiological action on the human body. Heliotropium verdcourtii is a deciduous shrub or small tree traditionally used in the treatment of various diseases including fever, dry cough, measles, convulsions, epilepsy, diarrhea, and other ailments. The chemical constituents of the roots of the plant were not investigated to date. The aim of the study was to investigate the phytochemicals present in the roots of Heliotropium verdcourtii. The freshly collected root of the plant was chopped and air dried under shade. The dried and finely grounded plant root was extracted through maceration with n-hexane, chloroform/methanol (v/v 1:1), and methanol successively. The extracts were subjected to qualitative phytochemical tests for screening the classes of secondary metabolites present in the plant. Compound isolation of the chloroform/methanol (v/v 1:1) extract was performed through silica gel chromatographic separation. The structures of all isolated compounds were determined by spectroscopic methods as well as comparison with previous reports in the literature. The yields of n-hexane, chloroform/methanol (v/v 1:1), and methanol extracts were 2.2 g (0.4%), 25 g (5.0%), and 19.8 g (4.0%), respectively. The qualitative phytochemical test of the extracts revealed the presence of flavonoids, terpenoids, phenolics, saponins, glycosides and alkaloids. Silica gel chromatographic separation afforded a mixture of three isomeric triterpenoids identified as α-amyrin, β-amyrin, and bauerenol. To the best of our knowledge these bioactive compounds were isolated from the root of this plant, for the first time.

Nanotechnology has changed and developed all the sectors and working fields. Nanoparticles are one of the important evolutionary materials that have application in almost all the working areas such as catalysis, bioengineering, photoelectricity, antibacterial, anticancer, and medical imaging due to their unique physical and chemical properties. Traditionally used chemical and physical method of synthesis of nanoparticles have several disadvantages like using different chemicals, high cost, and most importantly they are hazardous to the environment. Counter to these disadvantages, a more eco‐friendly, easy, and cost‐effective green synthesis method is widely employed nowadays. Various parts of a plant are used as a fuel for reducing the metal ion salt. Plant extracts act as reducing, stabilizing, and capping agents. Besides these advantages, photosynthesized nanoparticles are nontoxic, more stable, and more uniform in size than their counterparts prepared by the traditional method. In this present review, the synthesis of various plant extract‐mediated metal and metal oxide nanoparticles is discussed along with their different applications. This review provides a comprehensive overview of key findings in green synthesis of metal and metal oxide nanoparticles and attempts to determine their possible synthesis mechanism. This article also focuses on factors affecting their synthesis, characterization, potential applications, and prospects.
