Edible flowers have been an integral part of human nutrition for centuries, being used as garnishes of individual dishes and also consumed fresh. This study determines and compares the essential and trace mineral composition of the three edible flowers of Allium cepa (onion), Carica papaya (papaya) and Cucurbita maxima (pumpkin) with four other commonly consumed edible flowers. Also, a comparative study of the three above-mentioned edible flowers with its respective fruit and leafy parts has been carried out. Macro-mineral and trace mineral contents were estimated by means of Inductively Coupled Plasma-Optical Emission Spectroscopy following the Association of Official Analytical Chemists (AOAC, 1990) method. Amongst the three chosen edible flowers, onion flowers contain the highest amount of potassium, calcium, sodium, zinc, and sulphur content, while the pumpkin flowers have the highest quantity of copper. Onion flowers have the highest quantity of calcium and manganese when compared to their stalk and bulb. Papaya flowers are a rich source of phosphorous and copper compared to their fruit and leaf counterparts. The test...

Plants and their parts are used to treat many infectious diseases due to the presence of phytoconstituents and avoid some side effects. The present study evaluated the phytochemicals, anti-diabetic, anti-urolithiatic, and anti-cancer activities of Prosopis juliflora seeds in various solvents such as aqueous, ethanol, and 85% ethanol. The preliminary works revealed the presence of secondary metabolites likes alkaloid, phenol, saponin, tannin, phytosterol and flavonoids. The work focused on the anti-diabetic properties of the extract by α-amylase, α-glucosidase methods. In-vitro anti-urolithiatic activity by titrimetric method showed that there was maximum activity, and its effect was compared with the standard drug cystone. The MTT assay was used to screen the crude extracts and the isolated compounds to assess their toxicity. The aqueous extracts of Prosopis juliflora seeds showed the inhibition effects of the cancer cell lines (MCF7), while there was no effect on the growth of normal cells. Such selective effects were found to be time-dependent. With respect to concentration (25 µg/ml, 50 µg /ml, 100 µg /ml, 250 µg /ml...

Environmental factors influence plant growth, morphology, as well as nature and quantity of secondary metabolites. Modification of abiotic factors during plant growth can impact the production of bioactive phytoconstituents. A six-month field study was carried out to assess the effect of different abiotic stresses on bioactive compounds (flavonoids, phenols, quercetin), acetylcholine sterase (AChE) inhibition and antioxidant capacity of two selected Allium species i.e. Allium cepa L. (AC) & Allium sativum L. (AS; family Amaryllidaceae). AC and AS plants were grown for six months (from November 2018 to April 2019) on three different soil types (i.e. black, red, clay-loamy) and various stresses (salinity, water deprivation, flooding, fertilizer, metal, shade) were applied on the plants. At the end of the season, plants were collected, dried and plant yield was determined. Hydro alcoholic extracts of all samples were prepared. Extract yield, total flavonoids (TFC), total phenols (TPC), AChE inhibition, and antioxidant activity were determined in all the extracts. The results show the varied response of AC & AS plants to different soil...

The study was designed to evaluate the anti-fatigue activity and biochemical effects of nootkatone in Balb-C mice. Thirty-six mice weighing 33-41g were randomly divided into six groups; 1) sedentary group, 2) sedentary group fed with 50 mg/kg nootkatone, 3) control group (exercise control), 4) exercise with 10mg/kg nootkatone group, 5) exercise with 25mg/kg nootkatone and 6) exercise with 50mg/kg nootkatone. Nootkatone was administered orally to mice from all groups. The anti-fatigue activity was assessed using a treadmill running test. Biochemical parameters were also evaluated. Nootkatone was found to increase run time on the treadmill and reverse the fatigue-induced reduction in liver/muscle glycogen, in addition to reducing lactate dehydrogenase (LDH) activity, blood urea nitrogen (BUN), and lactic acid. Moreover, nootkatone increases the activity of enzymes such as catalases, SOD and decreases lipid peroxidation. The data suggested that the nootkatone could extend the treadmill exercise duration in mice, as well as increase the tissue glycogen contents and decrease the malondialdehyde (MDA), lactic acid, BUN, CK and LDH levels. There was a...

Extract of Adhatoda vasica leaves has been used to treat various diseases and disorders in Ayurvedic and Unani medicine. Effect of ethanolic extract of Adhatoda vasica against gamma radiation-induced changes in terms of histological alterations in testes of Swiss albino mice were studied at post-irradiation intervals between 1-30 days. Mice exposed to 6 Gy gamma radiation showed radiation-induced sickness, including changes in the histology of testes. When ethanolic leaf extract of Adhatoda vasica was given orally at a dose of 900 mg/kg, body weight prior to irradiation showed significant protection. Leaf extract of Adhatoda vasica was also reported for the protective role in the spleen of Swiss albino mice exposed to 6 Gy γ-radiation. Mice were divided into four groups i.e., group (i) containing normal mice served as a control for each experimental stage; group (ii) mice given 900 mg/kg body wt. of Adhatoda vasica extract orally for 15 days; group (iii) mice exposed to gamma radiation (6 Gy) and group (iv) mice given Adhatoda vasica extract orally for...
