: Oxalis corniculata (Oxalidaceae) is a small decumbent and delicate appearing medicinal herb flourishing in warm temperate and tropical domains such as Pakistan and India. Main bioactive chemical constituents of Oxalis plant include several alkaloids, flavonoids, terpenoids, cardiac glycosides, saponins, phlobatannins along with steroids. Due to its polyphenolic, glycosides and flavonoid profile, it is proved to be protective in numerous ailments and exhibit various biological activities such as anti-fungal, anti-cancer, anti-oxidant, anti-bacterial, anti-diabetic, and cardioprotective. Moreover, bioactive phytochemicals from this plant possess significant wound healing potential. Our current effort intends to emphasize on the immense significance of this plant species, which have not been the subject matter of clinical trials and effective pharmacological studies, even though its favored usage has been stated. This review proposes that Oxalis corniculata possess potential for the cure of various diseases, however, further researches on isolation and characterization of bioactive compounds along with pre-clinical trials are compulsory to figure out its pharmacological applications.

A preliminary chemical characterization of main components of ethanolic extract with dried rhizomes of Smilax domingensis Wid. that grow in Cuba was done using a GCMS-QP2010 Ultra Shimadzu and the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. After sample derivatization 125 chemical compounds were registered by the equipment and from them, 35 different chemical components were characterized and reported for the first time from this part of the plant in our country. The results demonstrate the developed method could be employed as a rapid and versatile analytical technique for identification of chemical constituents and quality control of Smilax domingensis.

Phytochemical study of two medicinal plants from Ecuador, Tagetes terniflora Kunth, and Croton rivinifolius Kunth, led to the isolation and characterization of the major constituents present in the organic extracts obtained from these plants: 5-(4-acetoxy-1-butynil)-2,2’-bi-thiophene (1), 5-methyl-2,2’:5’,2”- terthiophene (2), patuletin (3) from Tagetes terniflora, and isocorydine (4), sweroside (5), tiliroside (6) from Croton rivinifolius. The structures of these compounds were established by spectroscopic analysis including two-dimensional NMR methods, MS, and comparison with published spectral data. They are recognized as secondary metabolites that represent the chemotaxonomy of Tagetes and Croton genera and could be responsible for the recognized medicinal properties attributed to these species. This paper deals with the first report that shows the presence of these compounds in these plants.
