Holy Basil

The research objectives of this study are to analyse the volatile compositions of different basil types available in Thai markets and to descriptively determine their aromatic qualities. Essential oils were hydro-distillated from fresh leaves of two Holy basil (Ocimum sanctum) varieties namely, white and red and other basil species, including Tree basil (O. gratissimum), Thai basil (O. basilicum var. thyrsiflorum), and Lemon basil (O. citriodorum). Oil physiochemical characteristics and volatile chromatograms from Gas Chromatography–Mass Spectrometry (GC-MS) were used to qualitatively and quantitatively describe the chemical compositions. Estragole, eugenol, and methyl eugenol were among the major volatiles found in the essential oils of these basil types. Classification by Principal Component Analysis (PCA) advised that these Ocimum spp. samples are grouped based on either the distinctive anise, citrus aroma (estragole, geranial and neral), or spice-like aroma (methyl eugenol, β-caryophyllene, and α-cubebene). The essential oils were also used for descriptive sensorial determination by five semi-trained panellists, using the following developed terms: anise, citrus, herb, spice, sweet, and woody. The panellists were able to differentiate essential oils of white Holy basil from red Holy basil based on the intensity of the anisic attribute, while the anise and citrus scents were detected as dominant in the Lemon basil, Tree basil, and Thai basil essential oils. The overall benefit from this research was the elucidation of aromatic qualities from Thai common Ocimum species in order to assess their potential as the raw materials for new food products.

Metabolic disorders are usually categorized as inborn metabolism defects, including carbohydrate metabolism deficits in enzymes, amino acids derived from proteins, and fatty acids released from lipids. A metabolic disorder, which arises from elevated body weight, diabetes, and obesity, has reached epidemic proportions in countries. This review discusses the metabolic disorders with respect to diabetes, obesity and liver disorders and their therapeutic management with selective Ocimum species. Ocimum genus contains more than 200 species and is one of the richest sources of diverse phytoconstituents, including fatty acids, saponins, flavonoids, terpenoids, phenols, tannins, etc. that are documented to be beneficial in the management of various metabolic disorders. The potential of selected Ocimum species in metabolic disorders is discussed by reviewing available preclinical and clinical studies and associated mechanisms of action and their effect on gene expression.

Ocimum species (Lamiaceae) have aroused great interest to the scientific community with respect to different biological properties attributed to their essential oils. The seasonal variation and antioxidant and fungical activities were carried out for the essential oil of Ocimum campechianum. Its essential oil showed an excellent yield (0.5–5.3%) throughout the season. The essential oils of leaves/stems and inflorescences were analyzed by GC and GC-MS to identify their volatile constituents and associate them with the antioxidant and antifungal activities. Methyleugenol was the main component in the leaves/stems (80.0-87.0%) and inflorescences (75.3–83.5%). The essential oil and the methyleugenol standard showed low antioxidant activity (<40%) against DPPH radical, but high antifungal activity against Fusarium oxysporum and Colletotrichum gossypii phytopatogens as well as the mycelial growth and spore germination of the fungi. The high levels of methyleugenol coupled with good fungicidal activity give great agroindustrial potential to this Ocimum species.

Abstract Objectives Ocimum is a genus of aromatic, annual and perennial herbs and shrubs, in the family Lamiaceae, native in Asia, Africa, South, and Central America. Ocimum includes about 150 species; of which the most well- known and widely used for culinary purposes is O. basilicum (basil). Ocimum species have been reported to exhibit anti-diabetic property. The objective of this study was to analyze Ocimum species for antidiabetic properties and identify compound(s) that may be best associated with its anti-hyperglycemic effects. Methods Sixteen Ocimum accessions consisting of three O.africanum, two O.americanum, four O.basilicum, one O.campechianum, two O.gratissimum, and three O.tenuiflorum accessions were cultivated using organic production system. Leaves were harvested at peak vegetative phase, lyophilized, and ground into fine particles and extracted with aqueous methanol. Results A primary evaluation of phytochemicals demonstrated the presence of eugenol, β-sitosterol, caffeic acid, chicoric acid, luteolin, oleanolic acid, rosmarinic acid, and ursolic acid in Ocimum species. Analysis of the crude extracts of the above 16 Ocimum accessions showed that O.tenuiflorum, O.gratissimum, and O.basilicum inhibited yeast alpha glucosidase activity. Of these, O.tenuiflorum demonstrated comparable IC50 inhibitory concentrations as acarbose, a widely-prescribed anti-diabetic medication. Additionally, further sub-fractionation of crude extracts retained and enhanced the alpha glucosidase inhibitory property, with O.tenuiflorum and O.gratissimum showing maximal inhibitory effects (60%–70% inhibition) that were comparable to acarbose (75% inhibition). Conclusions These studies suggest anti-hyperglycemic potential of O.tenuiflorum and O.gratissimum species. Funding Sources NIFA-USDA.
