Background From the last few years, the development and discovery of bioactive compounds and their potential properties from marine algae have been enhanced significantly. The coastal area is a huge storehouse for propitious algae. It has been the genuine reality that the consequence of marine algae as a source of different compounds is increasing. Main body Numerous advanced research devices are available for the discovery of synthetic compounds but still many researchers are working on natural bioactive compounds to discover their biological properties, which are useful to society. Marine algae are taking the preponderance of consideration from investigators owing to its phenomenon of biological activity like anti-cancer, anti-viral, cholesterol-reducing, and many more. A variety of compounds are collected from algae with specific purposes as they remain in an extremely ambitious and hard state; this condition is responsible for the synthesis of very particularly effective bioactive compounds. The present article is concentrating on the brown algae of the Gujarat coast, phlorotannins, polyphenol, phytosterol from brown algae, and their various applications. The main importance has been given to the secondary metabolites and various applications of marine brown algae. Conclusion From this review, it can be concluded that the prominent bioactive compounds from brown algae can cure many serious diseases. Besides, the potential biological activities of a special bioactive compound may represent the interest in the industry of pharmaceuticals, cosmeceutical, and functional foods.

Our study developed a HPTLC fingerprint profile of alkaloids and glycosides obtained from the methanol extracts of four different plant parts of Terminalia arjuna, T. bellerica and T. chebula, trees with cardio-protective values. The multiple qualitative phytochemical analyses of water, acetone, petroleum ether and methanol extracts from all the plant parts of Terminalia spp. detected the presence of alkaloids and glycosides, wherein the methanol extracts exhibited the presence of maximum alkaloids and glycosides. The chromatographic analysis of methanol extracts was carried out on silica gel 60F254HPTLC aluminium sheets with CAMAG Linomat 5 applicator. The plates were developed using ethyl acetate:toluene:formic acid (10:10:1; v/v/v) mobile phase. Alkaloids and glycosides were detected at 254 nm, 366 nm and 540 nm (after derivatization). These developed fingerprints would eventually be of great benefit in identifying or differentiating the alkaloids and glycosides in the form of marker compounds in the three Terminalia spp. mentioned.

Padina is rolled-blade-shaped marine brown algae that often have overgrown and has been well explored for its medicinal qualities. The various species of Padina release a wide range of promising chemical components as part of their chemical defense systems. In this context, a finding was conducted to explore the bioactive compounds using exceptionally sophisticated analytical techniques, such as high-performance thin-layer chromatography. Microchemical and biochemical derivatization was used in the investigation to confirm multi-class bioactive molecules and the antioxidant activity of the separated band. Microchemical derivatization ascertained the appearance of miscellaneous lipophilic substances, essential oils, volatile compounds, coumarin, and bitter principles. To determine the chemical standard of these algae, the qualitative (microchemical) screening of phytochemicals associated with flexible high-performance thin-layer chromatography was utilized. Moreover, biochemical derivatization, which generates a spectacular white band with a purple background to appear on the chromatogram, substantiates the antioxidant activity of a particular band.These results proffer a chromatographic profile of the antioxidant capability of three species of Padina's bioactive components, which will create the necessary information for the standardization and identification of marine algae. Mass spectrometry results revealed the presence of phytol compound from the diterpenoid class, which has antioxidant potential.

The Veraval coast situated at (20º54’30º N 76º21’20º E) the gulf of Kachchh, western coast of Gujarat, India. This site has a rich diversity of marine algae, corals and gastropods at intertidal region. The main aim of present study focused on occurrence and diversity of marine algae at coastal site. The study carried out in month of December- 2019. Algae collection was done during low tide situation, at this condition algae were collected with their holdfast/rhizoid. Total 33 species of algae were collected from three different phylum. Among these maximum 18 species were recorded from red algae, 8 species were recorded from green algae and 7 species were recorded from brown algae.

Background India is a diverse source of medicinal and aromatic plants. Desmodium species are one among them having importance in curing many human diseases. This herbaceous plant's species diversity minimizes problems with its pharmaceutical or herbal formulation. As a result, a detailed analysis of the phytochemistry of the Desmodium genus will allow for the proper use of this plant. Main body This review explores the distribution of Desmodium species and their various biological activities. Worldwide, 17 Desmodium species are found, while 13 species of Desmodium are found in India. Plants are mainly used in ayurvedic preparation for curing various diseases. Phytochemical examination of Desmodium species indicated the presence of isoflavones, glycosyl-flavonoids, coumarone-chromones, pterocarpons, triterpenoids, saponins, tetrahydroiso-quinolones, phenylethylamines, indole-3-alkylamines, lipids, and alkaloids. These genera also display various pharmacological activities, including anti-inflammatory, anticancer, analgesic, depressive, antipyretic, antidepressant, anti-diabetic, and antioxidant properties. Also it is valuable for febrifuges, remedies for dysentery and liver disease, wound healing, ulcer, antidote against snake bites, catarrh, abscesses and eye diseases, abdominal tumor, asthma, fever, nasal polyps, menstrual disorder, fever, colds and helps in kidney problems. Conclusion This review describes the distribution of various Desmodium species recorded by a different author, focusing on species recorded in Gujarat, India. Again, the review helps in the documentation of bioactive compounds from the Desmodium genus that may help rectify multiple severe diseases. Furthermore, the numerous biological potencies of the specific bioactive substance may characterize the interest in various pharmaceuticals and cosmeceuticals sectors.
