 Objective: The objective is to create 4 extracts of Centella Asiatica whole plants without using toxic chemicals based on an edible oil and water and to study the UV-vis absorption spectrum of the extracts.Methods: An extract of the whole plant was taken in fresh form with green leaves, made in to a paste by using an electric grinder and the paste mixed with water was heated with coconut oil at temperatures below 100 degree C. The oil part and water part of the extracts were then taken and analysed in an UV-vis spectrometer. The experiment was repeated by using Centella Asiatica whole plants dried in sun for a day.Results: The UV spectrum of the oil extract of undried Centella Asiatica whole plant showed absorption peaks at 413nm, 434 nm, 506nm, 537nm, 564nm, 610nm and 670nm. The oil extract of dried Centella Asiatica whole plant showed peaks at 413nm, and 670nm. The peaks between 434 nm and 670 nm in the oil extract were due to Chlorophyll. The strongest peak at 413 nm is the major signal of the extract and is thought to represent the flavonoid Rutin. The water part of the extract of the dried plants does not show any significant peak at 670nm of the chlorophyll.Conclusion: Four extracts of Centella Asiatica whole plant were studied. The oil part of the extracts showed a strong peak at 413 nm. The medicinal values of the 4 extracts of the plant need to be studied in detail.

A new compound, 1,3,7,9-tetrahydroxy-6 H-dibenzo[ b, d]pyran-6-one (1), together with 6 known compounds (2-7), was isolated from the extract of whole plants of Centella asiatica. The chemical structure was elucidated on the basis of spectroscopic and mass spectrometric analyses. All the isolates were evaluated for their cytotoxicities against 4 human cancer cell lines (MCF-7, HepG2, Hela, and A549). Among them, compound 1 was found to exhibit significant cytotoxicity on MCF-7 and HepG2 cancer cells with half-maximal inhibitory concentration values of 4.1 and 7.2 µM, respectively.

Abstract The majority of the population in Bangladesh uses traditional plant-based medicines to manage various ailments, including central nervous system (CNS) disorders. This review presents ethnobotanical information and relevant scientific studies on plants used in traditional healthcare for the management of various CNS disorders in Bangladesh. The information on the medicinal plants of Bangladesh effective against CNS disorders published in scientific journals, books, and reports was compiled from different electronic databases using specific key words. The present article provides comprehensive information on a total of 224 medicinal plant species belonging to 81 families used for the treatment of CNS disorders by the various peoples of Bangladesh. In total, we reviewed more than 290 relevant papers. In this study, leaves were found as the most often used plant organ, followed by roots, fruits, whole plants, barks, seeds, stems, rhizomes, and flowers. The Fabaceae family contributes the highest number of used species, followed by Rubiaceae, Lamiaceae, Cucurbitaceae, Vitaceae, Euphorbiaceae, Malvaceae, and Zingiberaceae. The most frequently used species (in decreasing order) are Asparagus racemosus, Centella asiatica, Stephania japonica, Aegle marmelos, Coccinia grandis, Tabernaemontana divaricata, Bacopa monnieri, Abroma augusta, and Scoparia dulcis. This review may serve as a starting point for a rational search for neuroactive natural products against CNS disorders within the Flora of Bangladesh. Graphic Abstract

Toxicity studies' quality control of drug plant-based products is an important aspect of pharmacological research. The purpose of this literature review is to extract about toxicity test on Centella asiatica. The plant component utilized, the test animals used, the type of toxicity test, evaluation, the findings, and conclusions of each test are all included in this review—the database used in PubMed. Most of the literature results obtained from this review indicate high safety in C. asiatica plants. The acute toxicity test is that the most frequently used toxicity test. The use varies from plant parts to whole plants, with minimal side effects reported and high in safety, so it can be concluded that C. asiatica is very prospective to be developed as a medicine.

The differentiation of phloem in plant tissue cultures offers a unique opportunity to study the development and structure of sieve elements in a manner that avoids the injury responses associated with the processing of similar elements in intact plants. Short segments of sieve elements formed in tissue cultures can be fixed intact while the longer strands occuring in whole plants must be cut into shorter lengths before processing. While iyuch controversy surrounds the question of phloem function in tissue cultures , sieve elements formed in these cultured cells are structurally similar to those of Intact plants. We are particullarly Interested In the structure of the plasma membrane and the peripheral ER in these cells because of their possible role in the energy-dependent active transport of sucrose into the sieve elements.
