Plant Essential Oils

The antifungal activities of 19 plant essential oils against six wood mold and stain fungi (Aspergillus niger, Penicillium citrinum, Trichoderma viride, Botryodiplodia theobromae, Fusarium moniliforme, and Alternaria alternata) were investigated with the in vitro medium method. The chemical compositions and volatilization rates of the essential oils were analyzed by gas chromatography–mass spectrometry and oven heating, respectively. Antifungal effects of the essential oils on fresh Pinus massoniana wood were evaluated by dipping treatment. The average antifungal efficacies of the essential oils varied from 0.1 to 1.0, and oils of Cinnamomum cassia, Syzygium aromaticum, and Thymus mongolicus showed the greatest antifungal activities and completely inhibited the growth of all six fungi. The essential oils presented great differences in their main chemical components, and a significant negative linear correlation (Pearson correlation coefficient = -0.627, p < 0.01) was found between antifungal efficacy and volatilization rate, indicating that both chemical composition and volatilization rate are important factors influencing the antifungal activities of essential oils. Eight essential oils effectively inhibited the growth of fungi in Pinus massoniana wood with an absorption of 65.51 g/m2 ± 13.78 g/m2, and they have the potential to be environmentally friendly anti-mildew agents.

Mimusops Elengi

Mimusops elengi Linn. is a plant with high medicinal and commercial value. Although several secondary metabolites have been reported from different species of this plant, there has been not much information available on the complete profile of phytochemical constituents in Mimusops elengi Linn. The HPTLC fingerprinting of methanol extract showed 6 peaks having maximum Rf values 0.10, 0.27, 0.34, 0.51, 0.72, and 0.80 at 254nm. The same extract showed 3 peaks having maximum Rf value 0.25, 0.29 and 0.49 at 366 nm. This study applies Gas chromatography-Mass spectrometry technique to determine the possible chemical components in the methanol extract of Mimusops elengi Linn. Unripened fruits reports for the first time most extensive profile of the plant. The determination and identification of bioactive chemical compounds is established and based on the peak area, retention time molecular weight, and molecular formula. GC-MS analysis of Mimusops elengi Linn. revealed the existence of the 2,2’ Methylenebis [3,4,6-trichloroanisole] which was found to be major component followed by Z-1,9-Hexadecadiene, Cyclopentaneundecanoic-acid, 4-Methyloctanoic acid and E-10-Dodecen-1-ol propionate. The results obtained may be helpful to the further study of pharmacological action for their promising utilization as therapeutic agents.

First Time

As a classic TCM prescription, LGZG has been widely used in clinical prevention and treatment of heart failure, nonalcoholic fatty liver, and hyperlipidemia. However, there are few studies on chemical components in recent years, and the basis of quality evaluation is not sufficient. This study was to find the active ingredients of the Lingguizhugan decoction using UPLC-MS/MS and network pharmacology. By comparing the retention time and MS dates of the reference and self-building database, the cleavage rules of chemical composition whose mass errors are less than 1 ppm(FL less than 3 ppm) are analyzed. On this basis, a network pharmacology method was used to find biomarkers for quantitative analysis. The results show that 149 compounds were preliminaries identified or inferred, including 63 flavonoids, 30 triterpenes, 22 phenylpropanoids, 13 organic acids, 6 lactones, 5 alkaloids, 4 anthraquinones, and 6 other compounds. According to the network pharmacology results, 20 chemical constituents were selected as the biomarkers, which were determined simultaneously for the first time, including poricoic acid A, poricoic acid B, glycyrrhizic acid, glycyrrhetinic acid, liquiritin, isoliquiritin, liquiritigenin, isoliquiritin apioside, cinnamic acid, caffeic acid, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid A, B, and C, atractylenolide I, II, and III, and coumarin. The methodological results show that the linearity, stability, precision, repeatability, and recovery of the method are satisfactory. Therefore, a comprehensive quality assessment system for LGZG was established on the basis of a systematic study of chemical substances and network pharmacology, which provided an important reference for the foundation of pharmacological action and its mechanics.

The transformation of high molecular weight components present in heavy oils into useable liquid fuels requires their decomposition by means of a variety of processes. The low molecular weight species produced recombine under controlled conditions to generate synthetic fuels. However, an important fraction undergo further recombination into higher molecular weight components, leading to the formation of coke. The optical texture of the coke can be related to its originating components. Those with high sulfur and oxygen content tend to produce cokes with small optical texture or fine mosaic, whereas compounds with relatively high hydrogen content are likely to produce large optical texture or domains. In addition, the structure of the parent chemical components, planar or nonplanar, determines the isotropic or anisotropic character of the coke. Planar molecules have a tendency to align in an approximately parallel arrangement to initiate the formation of the nematic mesophase leading to the formation of anisotropic coke. Nonplanar highly alkylated compounds and/or those rich in polar groups form isotropic coke. The aliphatic branches produce steric hindrance to alignment, whereas the polar groups participate in cross-linking reactions.

In modern era about 80% of the world population depends on herbal alternative system of medicine. Seventy thousand plants are used in medicine and about 2000 plants are used in Indian Ayurveda. The activities of the curative plants are evaluated by their chemical components. Few of them are important as a medicine but also posses poisonous or toxic properties. The toxicity is produced in them due to the synthesis of toxic chemical compounds may be in primary or secondary phase of their life. Most of the users of such medicinal plants in crude form are tribal and peoples living in the forests and their domestic stock . Most of the time these peoples may not aware about the toxicity of such plants used by them and probably get affected sometimes even leads to death. In the study area during the field survey of poisonous plants, information are gathered from the traditional practicing persons, cow boy and from shepherds. About 20 plant species belonging to 17 families are reported as a medicinal as well as toxic. From the available literature, nature of toxic compound and symptoms of their intake on human being are recorded. In the study area the plants like, Abrus precatorious commonly known as a Gunj or Gunjpala, Jatropha curcas , (Biodiesel plant), Croton tiglium (Jamalgota), Citrullus colocynthis (Kadu Indrawan, Girardinia diversifolia (Agya), Mucuna purriens (Khajkuairi), Euphorbia tirucali (Sher), E. ligularia (Sabarkand), Datura metel ( Kala Dhotara), Datura inoxia (Pandhara Dhotara) and Asparagus racemo-sus (Shatavari) etc . are some of the toxic plants used as a medicine and harmful also.

Stimulation Of

The widespread worldwide spread of acute respiratory diseases is an urgent problem in health care. Expressed polyetiology of respiratory diseases does not allow to limit the use of specific vaccine preparations and dictates the need to use to combat them a variety of non-specific means that stimulate the natural resistance of the human body. The main pharmacological action of sodium deoxyribonucleate is the stimulation of phagocytic activity of T-helpers and T-killers, increasing the functional activity of neutrophils and monocytes/ macrophages, providing regeneration and repair processes in the epithelial component of antiviral protection of the body. Based on the above, the study of the clinical efficacy of Derinat® in the form of spray in the treatment of acute respiratory viral infections is relevant.
