Abstract Background The Chenopodium genus is a plant family widely spread worldwide that includes various plant species reputed to possess several medicinal virtues in folk medicines. Chenopodium ambrosioides L. is among the most used plants in traditional medicines worldwide. This review aimed to highlight ethnomedicinal uses, phytochemical status, and pharmacological properties of C. ambrosioides L. Main body of the abstract The analysis of relevant data highlights various ethnomedicinal uses against human and veterinary diseases in forty countries. Most indications consisted of gastrointestinal tract dysfunctioning troubles and worms parasitemia. Around 330 chemical compounds have been identified in different plant parts, especially in its essential oil fractions (59.84%). However, only a few compounds—mainly monoterpenes and glycosides—have been isolated and characterized. Experimental pharmacological studies validated a large scale of significant health benefits. It appeared that many monoterpenes are antioxidant, insecticidal, trypanocidal, analgesic, antifungal, anti-inflammatory, anti-arthritic, acaricidal, amoebicidal, anthelmintic, anticancer, antibacterial, antidiabetic, antidiarrheal, antifertility, antifungal, anti-leishmanial, antimalarial, antipyretic, antisickling, antischistosomal, antiulcer, anxiolytic, immunomodulatory, molluscicidal, and vasorelaxant agents. Short conclusion Thus, the Chenopodium ambrosioides species necessitates further chemical studies to isolate and characterize new bioactive secondary metabolites and pharmacological investigations to precise the mechanisms of action before clinical trials.

Aims: One of the most important resources for the development of new drugs is a biologically active lead compound from natural sources. Biomedical researchers and pharmaceutical companies have a high interest in plant-derived molecules that can be used for drug development. Background: The collective knowledge of plants and their phytoconstituents would be of great benefit for the researchers involved in drug design. Therefore, we developed a unique and dynamic database GreenMolBD, to provide collective information of medicinal plants such as their individual profile, chemical constituents and pharmacological evidence, along with their plant parts and extract types based on different studies. Objective: We have also provided a complete profile of each compound, their physical, quantum, drug-likeliness, and toxicity properties (48 type’s descriptor) using in silico tools. Method: 1846 associated targets, related to individual compounds that are already explored in different studies, are also incorporated and synchronized. Result: GreenMolBD is freely accessible and searchable by keywords, plant name, synonym, common name, family name, family synonym, compound name, synonym, IUPAC name, InChI Key, target name and disease name. Conclusion: This is the first evidence-based database of bioactive molecules from medicinal plants specially grown in Bangladesh, which may help to explore and foster nature-inspired rational drug discovery in the future. Our database is continuously updating with the new information.

Cancer is a group of diseases which is categorized to differentiate into diverse cell types and move around in the body to sites of organogenesis that is key to the process of tumor genesis. All types of cancer fall into the group of malignant neoplastic diseases. In Bangladesh, cancer is now one of the foremost killer diseases and its personal, social, and economic bearing are huge. Plant-derived natural compounds (vincristine, vinblastine, etoposide, paclitaxel, camptothecin, topotecan, and irinotecan) are useful for the treatment of cancer. Since there is no extensive ethnobotanical research study in Bangladesh regarding the traditional uses of medicinal plants against neoplasms, therefore, a randomized ethnopharmacological surveys were carried out in 3 districts of Bangladesh to learn more about the usage of anticancer medicinal plants and their chemical constituents having antineoplastic activity. Comprehensive interviews were conducted to the folk medicine practitioners and medicinal plants as pointed out by them were photographed, collected, deposited, and identified at the Bangladesh National Herbarium. The various plant parts have been used by the healers which included whole plant, leaves, fruits, barks, roots, and seeds. This study evaluated considerable potential for discovery of novel compounds with less side effects in the management and prevention of malignancy in cancer.

Plant Wax

This review discusses the potential use of plant wax components, especially n-alkanes, as markers for estimating herbage intake, estimating the botanical composition of consumed herbage and studying digesta kinetics. Previous approaches to making these measurements are discussed briefly. Attention is drawn to the fact that current methods for estimating intake do not adequately allow for differences between individual animals. It is also suggested that the markers currently used to estimate botanical composition or study digesta kinetics are inadequate. The nature of the chemical constituents of plant waxes is briefly discussed and the concept of using alkanes to estimate intake is introduced. Particular emphasis is given to the fact that although the recovery of alkanes in faeces is not complete, intake can still be estimated using a pair of alkanes (one natural, one dosed) provided these have similar faecal recoveries. The accuracy of estimation of intake is discussed in terms of: obtaining a representative sample of herbage; alkane dosing and faecal sampling procedures; validity of the assumption of similar recoveries for the natural and dosed alkanes; sample preparation and analysis. Published comparisons of estimated and actual intakes are presented, with the conclusion that satisfactory results are obtained if intake is estimated using natural C33 alkane and dosed C32 alkane. The use of the different patterns of alkanes in herbage species, as a means of estimating botanical composition, is then discussed. Results are presented showing this can be done successfully with herbage mixtures or oesophageal extrusa. Procedures are then described for making the corrections for incomplete faecal alkane recovery, necessary to estimate the botanical composition of the herbage consumed by the free-grazing animal. This allows the quantification of the intake of individual plant species by individual animals, and it is suggested that this can be achieved without the need for oesophageally-fistulated (OF) animals. Differences in alkane levels between plant parts within a species are then discussed. It is suggested that these can lead to error in the estimation of intake, if OF animals should consume plant parts different from those consumed by the test animals. However, it is also suggested that differences in alkane levels between plant parts can be used to quantify the intake of these parts, in a manner analogous to the estimation of the intake of individual plant species. The usefulness of alkanes in studies of digesta kinetics is then discussed, principally in relation to the natural alkanes, which remain intimately associated with plant particles in the gut. It is suggested that natural alkanes could prove excellent markers for studies of particle breakdown and digesta flow. The preparation of natural 14C-labelled alkane, for use as a pulse dose in mean retention time studies, is also discussed.

Properties Of Soil

This paper investigates the effects of gypsum powder from the gypsum plant in Adigudem on chemical properties of soil as well as the yield of two major crops, wheat (Triticum aestivum) and barley (Hordeum vulgare). Three mixes of 10kg of soil with 0%, 10%, 30%, and 50% proportion of gypsum powder were used for pot experiments under glasshouse conditions at Mekelle University. One bulk soil sample was collected from a spot at 4 km from the eastern side of the plant. The chemical concentration of major elements Ca, K, Na, Mg, and Mn, and trace elements, Cd, Zn, Cu, Pb, Cr, and Fe in soil and plant parts were determined using an Atomic absorption spectrometer as well as NO3, PO4 and SO4 using UV-spectrometer. The results suggest that the gypsum powder enhances metals and anion content in soil and in crop parts compared to the control sample. The chemical constituents in soil and crop parts showed negligible variation with increasing proportions of gypsum powder. Gypsum loaded Ca, SO4, Mn, and Pb onto the soil, which exhibited higher Mg, Cu, Mo, Cd, NO3, and PO4 but the comparable concentrations of Fe, K, Zn, and Cr in decreasing order. However, a direct relationship was noted in chemical constituent loadings along the pathway:  powder-soil-crop in a similar fashion in the three mixes. Factor analyses revealed that wheat parts have a higher accumulation of nutrients than the barley parts with higher content in its growth soil blends.  As an extension of this research, the in-situ investigation is recommended to assess the direct impact of the gypsum powder emitted over the soil and crops.

The Nigerian essential oils of fresh Pterocapus soyauxii leaf, leaf stalk and stem bark were isolated by hydro-distillation using the adapted all glass Clevenger’s apparatus designed to British Pharmacopeia specifications. Chemical compositions of the plant parts were characterized using Gas Chromatography-Mass Spectroscopy (GC-MS). The leaf essential oil contained 12 compounds, out of which 10 were identified accounting for 93.91% of it. Leafstalk oil had 20 major compounds, which were characterised; they constitute 95.47% of the oil. 11 compounds make up 78.61% of stem bark oil, out of which 7 were characterised, responsible for 76.30% of it. Prominent compounds in the leaf oil were cembrene (43.59%), a monocyclic diterpenoid, eremophilene (29.72%), and azulene derivatives (6.62%), which are polycyclic aromatic compounds. Leaf stalk oil was dominated by hexadecane (32.97%), cis- and trans- β-ocimene (11.60 and 7.74% respectively) and heptanol (8.39%). Major compounds in stem bark oil were neophytadiene (22.11%), 2-heptanol (19.27%) and 3,7,11,15-Tetramethyl-2-hexadecene-1-ol (14.35%). Other prominent compounds in the stem bark oil are 4-propyl-cyclohexene (4.83%), 3-Eicosyne (7.63%), 3,7,11-trimethyl-14-(1-methylethyl-[S-(E,Z,E,E)]-1,3,6,10-cyclodecatetraene (5.10%) and methyl-Z-5,8,11,14,17-Eicosapentaenoate (3.01%). Notable compounds of biological importance and in appreciable amounts in the oils include phytol (6.93%), squalene (1.14%) and ambrial (1.97%). Fragmentation patterns in the mass spectrum of some unidentified compounds are also presented which are unique features of the oils. Interesting classes of compounds in the three oils include monoterpenes, sesquiterpenes, diterpenes, naphthalenes, alcohols and hydrocarbons.
