Nature is an amazing source for food, shelter, clothing and medicine. An impressive number of modern drugs are isolated from many sources like plants, animals and microbes. The development of natural products from traditional medicines is of great importance to society. Modern concepts and methodologies with abundant clinical studies, unique diversity of chemical structures and biological activities aid the modern drug discovery process. Kedrostis foetidissima (Jacq.) Cogn., a traditional medicinal plant of the Cucurbitaceae family, is found in India, Sri Lanka, Ethiopia and Western Malaysia. Almost all parts of the plant are used in traditional systems of medicines and reported having medicinal properties in both in vitro and in vivo studies. In the last few years, extensive research work had been carried out using extracts and isolated phytoconstituents from Kedrostis foetidissima to confirm its pharmacology and biological activities. Many scientific reports show that crude extracts and extensive numbers of phytochemical constituents isolated from Kedrostis foetidissima have activities like antimicrobial, antioxidant, anticancer, gastroprotective, anti-inflammatory and various other important medicinal properties. The therapeutic properties of the plants are mainly attributed to the existence of phytoconstituents like phenols, alkaloids, flavonoids, tannins, terpenoids and steroids. This comprehensive review in various aspects gave a brief overview of phytoconstituents, nutritional values and medicinal property of the plant and might attract the researchers to explore its medicinal activity by discovering novel biologically active compounds that can serve as a lead compound in pharmaceutical and food industry.
Duckweed, a floating macrophyte, has attracted interest in various fields such as animal feedstocks and bioenergy productions. Its enriched nutritional content and rapid growth rate make it particularly promising. However, common laboratory cultures of duckweed often experience fronds layering, diminishing the efficiency of sunlight capturing due to limited surface area on conventional cultivation platforms. In this work, we aimed to address the issue of fronds layering by introducing a novel cultivation platform - a superhydrophobic coated acrylic sheet. The sheet was prepared by spray-coating a suspension of beeswax and ethanol, and its effectiveness was evaluated by comparing the growth performance of giant duckweed, Spirodela polyrhiza, on this platform with that on a modified version. The superhydrophobic coated acrylic sheet (SHPA) and its variant with a metal mesh added (SHPAM) were employed as growing platforms, with a glass jar serving as the control. The plantlets were grown for 7 days with similar growth conditions under low light stress (25 μmol/m2/s). SHPAM demonstrated superior growth performance, achieving a mass gain of 102.12 ± 17.18 %, surpassing both SHPA (89.67 ± 14.97 %) and the control (39.26 ± 8.94 %). For biochemical compositions, SHPAM outperformed in chlorophyll content, protein content and lipid content. The values obtained were 1.021 ± 0.076 mg/g FW, 14.59 ± 0.58 % DW and 6.21 ± 0.75 % DW respectively. Therefore, this work proved that incorporation of superhydrophobic coatings on a novel cultivation platform significantly enhanced the biomass production of S. polyrhiza. Simultaneously, the biochemical compositions of the duckweeds were well-maintained, showcasing the potential of this approach for optimized duckweed cultivation.
