Cordia macleodii, an important medicinal plant traditionally used for the treatment of various disorders, including wound healing, jaundice, gastric ulcer, hepatoprotective activity and antivenom potential, thus the plant showed the high antioxidant properties. Successive extraction of leaf and barks powder with methanol and water was tested for quantitative determination of total phenolics, total flavonoids and various in vitro antioxidant activities. Phytochemical screening of crude plant extracts revealed the presence of sterols, alkaloid, flavonoid, phenolic, Reducing sugar, glycosides, tannins and saponins. All extracts showed the significant total phenolic and flavonoid contents and as well as radical scavenging and iron-chelating activities. Among all, methanol leaf extract was observed to be higher antioxidant activity than that of other extract. The methanol extracts showed greater antioxidant activity by DPPH scavenging the free radical with IC 50 values of 7.63 ± 0.38 μg gm-1 along with scavenged free radical in a concentration depended manner, which is compare to the standard ascorbic acid. Our results revealed that the presence of grater antioxidant activity of C. macleodii extract may be due to the high level of flavonoid and phenolic content in the plant. These results clearly indicated that C. macleodii is an effective natural antioxidant.

Indian mustard or Brassica juncea (B. juncea) is an oilseed plant used in many types of food (as mustard or IV range salad). It also has non-food uses (e.g., as green manure), and is a good model for phytoremediation of metals and pesticides. In recent years, it gained special attention due to its biological compounds and potential beneficial effects on human health. In this study, different tissues, namely leaves, stems, roots, and flowers of three accessions of B. juncea: ISCI 99 (Sample A), ISCI Top (Sample B), and “Broad-leaf” (Sample C) were analyzed by HPLC-PDA/ESI-MS/MS. Most polyphenols identified were bound to sugars and phenolic acids. Among the three cultivars, Sample A flowers turned were the richest ones, and the most abundant bioactive identified was represented by Isorhamnetin 3,7-diglucoside (683.62 µg/100 mg dry weight (DW) in Sample A, 433.65 µg/100 mg DW in Sample B, and 644.43 µg/100 mg DW in Sample C). In addition, the most complex samples, viz. leaves were anal...

Profound research has been done on the medicinal value of Brassica nigra (BN) seeds, and the leaves of the plant have been investigated in this study. The methanol extracts of the leaves were subjected to several in vitro studies. Among the four parts of this experimental plant seed extracts, which showed better antimicrobial activity in the initial screening test, were selected for further investigations. Though a floral extract with chloroform solvent showed refusal activity against five tested bacteria. However, maximum zone of inhibition observed in seed extract with polar and non polar solvents such as Pet. Ether, Chloroform and methanol against S. aureus (17.90 ± 2.1), P. mirabilis (17.8±4.02), E. aerogens (15.71.4±0.2), P. vulgaris (14.7±2.8), E. coli (11.47±3.3). Comparison of the antimicrobial activities of the fractions with that of the crude extract indicated that the non-polar fractions in many cases are stronger in activity at the two concentration levels than the crude extract. Results of the present study indicated that seed extracts with polar and nonpolar solvents can be exploited for future antimicrobial drugs against selected pathogenic bacterial strain.

The objective of the study was to carry out phytochemical, nutritional and antimicrobial evaluations of the aqueous extract of Brassica nigra seeds. The nutritional and phytochemical analyses were carried out by adopting standard methods. The antimicrobial study was carried out by using agar well diffusion method. The nutritional evaluation of the seeds of Brassica nigra showed that it contained moisture 4.16%, crude fibre 0.30%, crude fat 30.30%, ash 5.14%, crude protein 24.70% and carbohydrate 35.40%. The phytochemical screening of the seeds indicated the presence of saponins, alkaloids, flavonoids, glycosides, reducing sugar, phlobatannins and volatile oil. It was observed that the extract was effective in inhibiting Escherichia coli, Klebsiella pneumonia, Salmonella para-typhi, Pseudomonas aeuriginosa and Staphylococcus aureus, with the zone of inhibition ranging between 7mm and 23mm. The extracts of the Brassica nigra seeds can be used for common cold, painful joints and muscles (rheumatism), arthritis, edema, and increasing appetite. The seeds can also serve as a source of cooking oil because of the high content of crude fat and ethno medicine.

Phytochemical Composition and Antioxidant Potential of Brassica
Brassica Germplasm - Characterization, Breeding and Utilization, 2018
The edible parts of Brassica plants are a rich source of phytochemical compounds which possess strong antioxidant potential. These plants contain a variety of phytochemical compound including phenolics, polyphenols, phenolic acids, flavonoids, carotenoids (zeaxanthin, lutein, β-carotene), alkaloids, phytosterols chlorophyll, glucosinolates, terpenoids, and glycosides. These plants possess strong antioxidant potential in terms of metal reducing, metal chelating, lipid reducing and free radical scavenging activities. These also have a positive effect on the activity of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase, and ascorbate peroxidase. Among various species of genus Brassica studied for their phytochemical composition and antioxidant activity, Brassica oleracea leaves, florets and seeds have better phytochemical and antioxidant profile. Brassica juncea, Brassica napus, Brassica rapa and Brassica nigra are also the phytochemical and antioxidant rich species of genus Brassica. The phytochemical profile and antioxidant potential of Brassica plants make them the preferable candidates for nutritional and pharmaceutical applications.
Therapeutic potentials of Brassica juncea: an overview
2011
Diverse medicinal uses of different types of products obtainable from Brassica juncea have been known for centuries. Most such traditionally known uses of the plant have been centered on its seeds and oils obtainable from them. During more recent decades diverse bio-active molecules and their therapeutically interesting pharmacological properties of its green edible leaves have also been described, and they are now often considered to be effective substitutes for other so called "healthy" Brassica vegetables. However, little concentrated effort has yet been made to obtain a pharmacologically better defined phytopharmaceutical from this easily cultivable plant of commercial interest in many underdeveloped and developing countries. The main aim of this overview is to point out some possibilities for designing and developing such products from the plant for combating the rapidly spreading obesity epidemic in the developed countries and some other countries. Efforts to achieve such goals could as well be an economically more feasible, and culturally more acceptable, starting point for better understanding the potential health benefits of other vegetarian foods.
