The ancient world had huge faith on the herbal medicines for curing various ailments. Scoparia dulcis Linn. is a medicinal herb of family Scrophulariaceae is considered to be one of such plants which have remarkable curative property. Scoparia dulcis is the commonly known as Sweet broom weed and is distributed throughout the tropical and subtropical region of the world. This herbaceous weed comprises of typical morphological characteristics which are of great use. Dried or fresh leaves, fruits and some other parts of plant serve the purpose of providing with essential components for the body metabolism. Some of the scientific studies demonstrated about the bioactive compounds present in the plant extract. These bioactive compounds were flavonoids, polyphenols, tannins and terpenoids. The fresh and the dried leaves of the herb showed its richness in ascorbic acid content. Scoparic acid, scopadulcic acid, scopadulciol, scopadulin and ammelinare is the major chemical components to which have contributed to the medicinal effect of the plant. Ethnomedicinal application of this herb revealed its uses for diabetes, jaundice, stomach problems, skin disease, fever, kidney stones, reproductory issues and piles. Evidences reported its flawless activity in anti-diabetic, anti-inflammatory, anti-ulcer, antioxidant, anti-microbial and analgesic illnesses. The current review is concerned with morphological, phytochemical, pharmacological, therapeutic and nutritional aspects of the plant Scoparia dulcis. This review may assist one to acquire encapsulated concept about the herb.

Air pollution is a significant matter of concern in today's world. The current study objective is to determine the air pollution tolerance index (APTI) of Kolkata from five roadside medicinal plants, namely, Heliotropium indicum, Tridax procumbens, Cleome rutidosperma, Commelina benghalensis, and Euphorbia hirta. APTI was determined by fresh leaves extracts using four important plants physiological parameters such as relative water content, ascorbic acid (AA) content, total chlorophyll (Chl) content, and pH of leaf extracts. Three sites or areas were selected for the study in Kolkata. It includes a control area (Jadavpur), a moderately polluted area (Salt Lake, Sec V), and highly polluted area (Dunlop Bridge) based on the West Bengal State Pollution Control Board databases and previous study reports. For estimating Chl and AA content spectrophotometer and titration method were used, respectively. A higher APTI value was found in plants located at the control area and moderately polluted area. However, the lower amount of APTI value was found in plants located in the polluted area. The study concludes that air pollution has a severe impact on plant and human health. The plant species with high APTI value can be planted around industrial complexes, roadsides, and urbanized sites to monitor air pollution in greener and cost-effective way.

Oxalis corniculata Linn. is a highly useful and important traditionally used medicinal herbaceous plant which is found in tropical and subtropical areas of the world. The plant is commonly called creeping wood sorrel and it is belonging to the family Oxalidaceae. The plant has been used in different system of traditional medication for the treatment of diseases and ailments of human beings. The present review reveals the diverse ranges of phytomolecules which was previously isolated such as flavonoids, alkaloids, tannins, steroids, polyphenols, glycosidic compounds, lipids and volatile oil. The leaves of the plant contain medicinal substances like isovitexine, flavonoids, and vitexine-2-O-beta-D-glucopyrunoside. It is a rich source of essential fatty acids like palmitic acid, oleic, linolenic and stearic acids. It possesses various important pharmacological activities like antioxidant, anti-cancer, anthelmintic, antiinflammatory, antimicrobial, astringent, diuretic, febrifuge, cardio-relaxant and stomachic properties. These reports are very encouraging and indicated that the herb should be studied more details for its future therapeutic benefits. The current review article briefly describes the botanical features, ethnomedicinal uses, pharmacological properties and phytochemical composition of this medicinal herb. The present study is an attempt to combine and document the necessary information on different aspects of Oxalis corniculata and highlights the need for research and development.

Trianthema portulacastrum Linn. (Biskhapra) is an annual herb belongs to the family Aizoacae, which is used to treat for many oxidative stresses related diseases. The current study was done to characterize the organoleptic and proximate characteristics and to estimate the phytochemical components and to investigate antioxidant activity of aqueous extracts of leaves of the plant. The results showed that total phenolic, flavonoids and tannin content are 112.96±0.93 mg Gallic Acid Equivalent/g Dry Weight, 164.84±0.91 mg Quercetin Equivalent/g Dry Weight and 11.79±0.37 mg Tannic Acid Equivalent/g Dry Weight, respectively. Total protein and amino acids contents are 193.56±2.68 mg BSA Equivalent/g Dry Weight and 128.79±3.19 mg Tyrosine Equivalent/g Dry Weight, respectively. Total polysaccharide, lipid and ascorbic acid content are 117.85±6.20 mg Dextrose Equivalent/g Dry Weight, 9.10% and 21.13 mg Ascorbic Acid Equivalent/g Fresh Weight, respectively. Inhibition percentage of antioxidants assays such as DPPH, ABTS and H2O2 are 80.68±0.83%, 77.27±0.93% and 72.83±0.86%, respectively. From the results may be concluded that the leaves of the plant possess biologically active secondary metabolites that can be highly applicable for the healing purposes of oxidative stress related diseases.
