Background:The active components of Horcha-6 were identified using liquid chromatography with tandem mass spectrometry.Also,we investigated the potential mechanisms that explain why Horcha-6 may be effective in treating migraines through the use of network pharmacology and a rat migraine model.Methods:After identifying the active components of Horcha-6,the corresponding genes of the active components’target were obtained from the Universal Protein database,and a“compound-target-disease”network was constructed using Cytoscape 3.9.0 software.For the in vivo experiments,nitroglycerin was injected intraperitoneally into rats to create a migraine model.Pre-treatment with Horcha-6 was administered orally for 14 days,and rats were subjected to migraine-related behavior tests.RNA sequencing was performed to identify the gene expression regulated by Horcha-6 in the trigeminal nerve.Results:A total of 903 chemical components of Horcha-6 have been collected in the liquid chromatography with tandem mass spectrometry.We discovered 55 of the Horcha-6 bio-active components that were evaluated based on their Percent Human Oral Absorption(≥30%)and DL values(≥0.185)on the traditional Chinese medicine systems pharmacology database.The“compound-target-disease”network contained 163 intersection targets with the migraine state.Gene Ontology analysis indicated that these components significantly regulated the immune response,vascular function,oxidative stress,etc.When Kyoto Encyclopedia of Genes and Genomes enrichment analysis was performed,we observed that most of the target genes were significantly enriched in the inflammation and neuro-related signaling pathway,toll-like receptor signaling pathway,neuroactive ligand-receptor interaction,etc.These predictions were further demonstrated via in vivo animal model experiments.The RNA sequencing results showed that 41 genes were down-regulated(P<0.05)and 86 genes were up-regulated(P<0.05)in the Horcha-6 treated group compared with the untreated group.Those genes were mainly i 展开更多

Thermal drying could lead to the deterioration of substance which affect its nutraceutical and chemical properties. Hence, thermal stability of substance is necessary in course of its drying to acertain the degree of temperature it will be subjected to. In this research, sclerotium of Pleurotus tuberregium is subjected to thermogravimetric analysis, differential thermal analysis and differential scanning calorimetry. Both thermogravimetric analysis and differential thermal analysis were conducted from ambient temperature to 1000°C at a rate of 20°C/min constant heating rate, while differential scanning calorimetry was conducted from ambient temperature to 400°C at a rate of 10°C/min constant heating rate. Besides, the oxides contents of sclerotium of Pleurotus tuberregium were determined using x-ray fluorescence analysis and the mircostruture was determined with scanning electron microscopy. It was discovered that complete dehydration of the sample ended at about 110.38°C and oxidation reaction occurred between 233.42°C to 373.82°C with release of heat by the sample. Sclerotium of Pleurotus tuber-regium is thermal stable up to 233.42°C with decompostion of steroid which is its second major component at about 400°C to 480°C. The x-ray fluorescence analysis of sclerotium of Pleurotus tuber-regium revealed that Na<sub>2</sub>O, MgO, SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, and Fe<sub>2</sub>O<sub>3</sub> are the major compound and SEM analysis showed that it is a solid with amorphous structure having some fibrous skeleton. This study revealed that sclerotium of Pleurotus tuberregium could be dried to minimal moisture content without the deterioration of its nutritional and medinicnal properties. 展开更多

Efficient utilization of isabgol(Plantgo ovata Forsk.)straw biomass through preparation of bio-active organic fertilizer in a natural composting process has not been studied.In this study,phosphate rock and silicate mineral(mica)powder were used as natural sources of phosphorus(P)and potassium(K),respectively.Cow dung slurry as a natural decomposer was mixed with the straw biomass at a 10:1(weight/weight)ratio along with mineral powder.Then,nutrient-mobilizing bio-inoculants were used in the composting process after attaining thermal stabilization.The agronomic effectiveness of the resulting bio-active compost(BAC)as a bio-organic fertilizer was compared with that of conventional organics(farmyard manure and vermicompost)and chemical fertilizer(CF)by growing isabgol under field conditions.Composting with the natural sources of P and K along with the bio-inoculants increased the total nitrogen(13.6 g kg^(-1)),P(38.7 g kg^(-1)),and K(31.2 g kg^(-1))contents in the final product(i.e.,BAC)compared with composting without the mineral powder and bio-inoculants.Application of BAC remarkably improved the seed yield(2.5%)and husk quality of isabgol in comparison with conventional organics and CF.Compared with CF,BAC significantly boosted the economic yield of isabgol by improving the husk recovery(2.5%)and mucilage yield(4.12%).Furthermore,BAC significantly improved the soil quality by increasing organic carbon(C),available nutrients,and microbial biomass C contents,as well as enzyme activity.The positive correlation between soil and plant parameters also highlighted the benefits of BAC for isabgol production through soil quality improvement.Therefore,it can be considered as a zero-waste technology,whereby a large quantity of straw biomass generated from isabgol cultivation,which contains essential nutrients,can be recycled back to the soil.Furthermore,BAC can be effectively used as a bio-active organic fertilizer,particularly in systems where chemical inputs are restricted,such as organic agriculture. 展开更多

Traditional Medicine (TM) and their secondary metabolites are being increasingly recognized as useful complementary treatments toward the cancer. A large number of clinical studies have reported and proven concern of cancer patients. Here we have also reported recent studies on the biochemical and cellular mechanisms of Traditional Medicine (TM). Nowadays, Chemotherapy and surgery are standard methods for treatment of cancer, but still it’s not been fully successful. Some progress has been made in cancer diagnosis and treatment, but high incidence rate of cancer and low survival rate of patient are still being reported worldwide. Since ancient times, a number of traditional medicines known as Ayurveda, Siddha, Unani, Iranian, Chinese, Korean, acupuncture, Muti, Ifa, and African medicine are widely used for therapeutic purposes and are becoming popular as Traditional Medicine (TM). It has been reported that plants synthesize plethora of “secondary metabolites” or “phytochemicals”, proven to possess anti-mutagenic and anti-cancer properties in many research studies. There are many possibilities for further organized research for screening of medicinal plants for their potential and efficacy against chronic diseases such as a cancer and other inflammatory diseases. Therefore, researcher’s interest should be in identification and standardization of new anti-cancer drug with low side effects and greater efficacy, that is easily acceptable in medical community and which may overcome the challenges in present and future cancer therapy. This review explores therapeutic value of certain bio-active principals of plant which could serve as potential pharmacologically active drug for treatment of cancer in future. 展开更多

Inhibitors of pancreatic a-amylase offer an effective strategy to lower the levels of postprandial hyperglycemia by controlof starch breakdown. Among 86 fungal endophytes isolated from 15 medicinal plants Aspergillus terreus-AFl04S, Aspergillusegypticus-HT166S and Penicillium sp.-CC200 exhibited strong pancreatic amylase inhibitory potential were selected. Endophyteswere subjected to ethyl acetate extraction and tested for a-amylase inhibition, in order to assess and evaluate their inhibitory potentialon pancreatic a-amylase. Analysis showed concentration dependent enzyme inhibition up to 83% with half inhibition (IC50) valuesfor less 25 mg.mL1, which is lower than acarbose as control. It was observed 3-fold increasing of Vmax and maintenance Km atcontrol level in the presence of extracts A. terreus-AFl04S and Penicillium sp.-CC200, while in presence of extract A.egypticus-HT166S Km was doubled, and Vmax was maintained at the control level. Kinetic studies allow proposing the competitivemode of a-amylase inhibition by extracts A. egypticus-HT166S and uncompetitive inhibition by extracts A, terreus-AFl04S andPenicillium sp.-CC200. 展开更多
