Foeniculum Vulgare

World Health Organization (WHO) estimated that 80% of the population of developing countries use traditional medicines, mostly natural plant products, for their primary health care needs. In the past few decades, the medicinal value of plants has been assumed more important dimension owing largely to the discovery that extracts from plants contain not only primary metabolites but also a diverse array of secondary metabolites with antioxidant potential. Medicinal plants are potential sources of natural compounds with biological activities and therefore attract the attention of researchers worldwide. Antioxidants are vital substances which possess ability to protect the body from damage due to free radical-induced oxidative stress. The purpose of current study was to determine the antioxidant activities and bioactive components of Foeniculum vulgare (fennel) (Samonsabar) seeds by using UV Visible Spectrophotometer (UV-Vis) and Gas Chromatography-Mass Spectrometry (GC-MS). Aqueous extract of fennel seeds showed more antioxidant activity (IC50: 0.28 ug/ml) than ethanolic extract (IC50: 0.83 ug/ml) and comparable to standard antioxidant, ascorbic acid (IC50: 0.59 ug/ml). GC-MS analysis was fruitful in identification of compounds based on peak area, retention time, molecular formula, molecular weight, MS Fragmentions and pharmacological actions. Ten bioactive phytochemical compounds from aqueous extracts and 11 from ethanolic extract of fennel seeds were identified. These findings indicated that fennel seeds are potential to provide preventive properties against oxidative damage. These results will give scientific information for quality control of indigenous drug to herbal medicine users and local practitioners using fennel for different types of ailments

Pharmacological Potential

Crocus sativus L. (saffron) has been traditionally used as a food coloring or flavoring agent, but recent research has shown its potent pharmacological activity to tackle several health-related conditions. Crocus sp. leaves, and petals are the by-products of saffron production and are not usually used in the medicine or food industries. The present study was designed to determine the chemical composition of the water and ethanolic extracts of C. sativus leaves and test their cytotoxic activity against melanoma (IGR39) and triple-negative breast cancer (MDA-MB-231) cell lines by MTT assay. We also determined their anti-allergic, anti-inflammatory, and anti-viral activities. HPLC fingerprint analysis showed the presence of 16 compounds, including hydroxycinnamic acids, xanthones, flavonoids, and isoflavonoids, which could contribute to the extracts’ biological activities. For the first time, compounds such as tectoridin, iristectorigenin B, nigricin, and irigenin were identified in Crocus leaf extracts. The results showed that mangiferin (up to 2 mg/g dry weight) and isoorientin (8.5 mg/g dry weight) were the major active ingredients in the leaf extracts. The ethanolic extract reduced the viability of IGR39 and MDA-MB-231 cancer cells with EC50 = 410 ± 100 and 330 ± 40 µg/mL, respectively. It was more active than the aqueous extract. Kaempferol and quercetin were identified as the most active compounds. Our results showed that Crocus leaves contain secondary metabolites with potent cytotoxic and antioxidant activities.

Introduction: Imbalance between total energy intake and expenditure causes accumulation of excess fat and sugar in the body which leads to development of diabetes mellitus type II, obesity, and metabolic syndrome. These harmful diseases accelerate aging and cause fatal metabolic disorders as people age. Inhibition of pancreatic lipase, and alpha glucosidase digestive enzymes is a step that can reduce excess fat and sugar from the body, which is an essential component of healthy aging. Methodology: In this study, aqueous and 50% ethanolic extracts of Hibiscus sabdariffa were investigated for their inhibitory activities on pancreatic lipase and alpha-glucosidase, in addition to their antioxidant activities (using UV-vis spectrophotometer). Results: Both extracts displayed antioxidant properties, indicated by IC50 of 5166.80 mg/mL for H. sabdariffa aqueous extract and 2809.10 mg/mL for H. sabdariffa 50% ethanolic extract. The extracts also suppressed the activities of pancreatic lipase and alpha-glucosidase enzymes, which suggests possible antiobesity and anti-diabetic activities. H. sabdariffa aqueous extract inhibited pancreatic lipase activity with IC50 of 167.5+/-12.7 mg/mL, whereas H. sabdariffa 50% ethanolic extract inhibited the enzyme with an IC50 of 790.65+/-16.02 mg/mL. Both H. sabdariffa aqueous and ethanolic extracts also successfully inhibited alpha-glucosidase enzyme activity with IC50 949.88 +/-10.83 mg/mL, and 378.33 +/-4.20 mg/mL, respectively. Conclusion: Taken together, the outcome of the investigations offers the possibility of the extracts as an anti-obesity, anti-diabetic, anti-metabolic and anti-aging agent, which can be developed into supplements for adults to prevent the occurrence of these prevalent diseases and delay the onset and effects of aging.
