Nowadays there is a need for scientific justification of plants that have been used in traditional medicine because of loss of information, improvement of therapy and deforestation that is taking place. The majority of the natural products are compounds biosynthetically derived from primary metabolites and are generally categorized as secondary metabolites. These are the major sources of the pharmaceutical industry to discover novel drugs. The basis for interest in natural product chemistry serves as a lead compound for newer drugs, give as much information on possible mechanism and thus on the molecular origin and basis of diseases. Natural products are permanent challenges with respect to total synthesis and stimulate the development of new reagents and reactions. The present study has been taken up to review one of the ethno medicinal significant of Ipomoea pes-tigridis L plant belonging to the family convolvulaceae. The ethno medical information of the plant reveals that the herb Ipomoea pes-tigridis Linn was used as an antidote to dogbite, boils and carbuncles, the leaves were applied as a poultice for boils, carbuncles and sores. The root of this plant was found to possess purgative action. The phytochemical studies on the leaves have been reported for the presence of carbohydrates, proteins and resins.

Major Chemical

Medicinal plants have been known as a rich source of natural products (NPs). Due to their diverse chemical structures and remarkable pharmacological activities, NPs are regarded as important repertoires for drug discovery and development. Biebersteinia plant species belong to the Biebersteiniaceae family, and have been used in folk medicines in China and Iran for ages. However, the chemical properties, bioactivities and modes of action of the NPs produced by medicinal Biebersteinia species are poorly understood despite the fact that there are only four known Biebersteinia species worldwide. Here, we reviewed the chemical classifications and diversity of the various NPs found in the four known Biebersteinia species. We found that the major chemical categories in these plants include flavonoids, alkaloids, phenylpropanoids, terpenoids, essential oils and fatty acids. We also discussed the anti-inflammatory, analgesic, antibacterial, antioxidant, antihypertensive and hypoglycemic effects of the four Biebersteinia species. We believe that the present review will facilitate the exploration of traditional uses and pharmacological properties of Biebersteinia species, extraction of the NPs and elucidation of their molecular mechanisms, as well as the development of novel drugs based on the reported properties and mode-of-action.

Medicinal plants are the backbone of Traditional systems of medicine like Ayurveda and Siddha. Solanum xanthcarpum (Solanaceae) (SX) is one of the most widely used medicinal herbs in Ayurvedic Pharmacopia. Me- dicinal plants have been of age-long remedy for human diseases because they contain components of therapeutic value. Plants are rich sources of ecologically developed secondary metabolites, which are potential remedies for different ailments. Kantakari (SX) of the family Solanaceae is one of the ‘dasamoola' and widely used drugs in Ayurveda. Dasamoola means a combination of ten plant roots together. It comprises roots of five big or major trees (Brihat panchmoola) and roots of five small trees or major herbs (Laghu panchmoola). Various studies indicated that SX contains steroidal glycoalkaloid solasodine, β-solamagrine and solasonine. The indigenous uses of plants also indicate anti-inflammatory, Antispermatogenic, Antidiabetic, Antiasthmatic, Molluscidal activity, useful in in- fantile atopical dermatitis, Cytoprotective, anticancer, insecticidal, insect repellent properties and diuretic activities. Therefore, the present investigation was intended to evaluate the preliminary phytochemical characters of this plant.

Background: Diabetes is a chronic disease affecting a large population worldwide and stands as one of the major global health challenges to be tackled. According to World Health Organization, about 400 million are having diabetes worldwide and it is the seventh leading cause of deaths in 2016. Plant based natural products had been in use from ancient time as ethnomedicine for the treatment of several diseases including diabetes. As a result of that, there are several reports on plant based natural products displaying antidiabetic activity. In the current review, such antidiabetic potential compounds reported from all plant sources along with their chemical structures are collected, presented and discussed. This kind of reports are essential to pool the available information to one source followed by statistical analysis and screening to check the efficacy of all known compounds in a comparative sense. This kind of analysis can give rise to few numbers of potential compounds from hundreds, whom can further be screened through in vitro and in vivo studies, and human trails leading to the drug development. Methods: Phytochemicals along with their potential antidiabetic property were classified according to their basic chemical skeleton. The chemical structures of all the compounds with antidiabetic activities were elucidated in the present review. In addition to this, the distribution and their other remarkable pharmacological activities of each species is also included. Results: The scrutiny of literature led to identification of 44 plants with antidiabetic compounds (70) and other pharmacological activities. For the sake of information, the distribution of each species in the world is given. Many plant derivatives may exert antidiabetic properties by improving or mimicking the insulin production or action. Different classes of compounds including sulfur compounds (1-4), alkaloids (5-11), phenolic compounds (12-17), tannins (18-23), phenylpropanoids (24-27), xanthanoids (28-31), amino acid (32), stilbenoid (33), benzofuran (34), coumarin (35), flavonoids (36-49) and terpenoids (50-70) were found to be active potential compounds for antidiabetic activity. Of the 70 listed compounds, majorly 17 compounds are from triterpenoids, 13 flavonoids and 7 are from alkaloids. Among all the 44 plant species, maximum number (7) of compounds are reported from Lagerstroemia speciosa followed by Momordica charantia (6) and S. oblonga with 5 compounds. Conclusion: This is the first paper to summarize the established chemical structures of phytochemicals that have been successfully screened for antidiabetic potential and their mechanisms of inhibition. The reported compounds could be considered as potential lead molecules for the treatment of type-2 diabetes. Further, molecular and clinical trials are required to select and establish the therapeutic drug candidates.
