Pegagan plant (Centella asiatica (L) Urban) is one of the medicinal plant that has many benefits, so it attracts the attention of experts to research and develop it in the context of exploring new drugs that come from nature. The porpose of researc was to formulate between  pegagan leaves and corn patch in the manufacture of cold flour and characterize pegagan leaves and corn patch. The research of method was carried out, making corn starch, making cold powder, and the tests carried out were hedonic tests, irritation tests and adhesion tes,. The results obtained from the Hedonic power test from the best treatment are the colors for F1 treatment which is 3.87, F1 texture which is 4.20 and aroma at F3 which is 5. Adhesion test results obtained are 182.49 seconds of F1 action, and irritation test in F1 treatment, it was found to be negative (-) or no irritation.

The aim of this research was to produce three-layer Medium Density Particleboard (MDP), with the addition of impregnated paper, in the inner layer, in proportions of 1; 5 and 20%. In this study, MDP was composed with particles of small size in outer layers, and larger particles in internal layer. After panel manufacturing, physical and mechanical tests based on Brazilian Code ABNT NBR 14.810 were carried out to determine moisture content; density; thickness swelling; water absorption; modulus of rupture (MOR) and modulus of elasticity (MOE) in static bending and internal adhesion. Test results were compared to commercial panels, produced with 100% Eucalyptus, considering the requirements specified by Brazilian Code. Properties presented values close to normative specifications, indicating positively the possibility of production of MDP using addition of waste paper impregnated.

Naturally God gifted medicinal plants which contain more potentially active compounds their characterization and isolation are very important and can provide us a great help in making new drugs to cure many diseases. Our current attempt was made to obtain the ethanolic extracts of medicinal plant Cerastium fontanum using a hot continuous soxhlet process and also via maceration method. The concentrated dried fraction extracts of Cerastium fontanum such as aqueous, n-hexane, ethyl acetate and dichloromethane were achieved using liquid-liquid extraction which were then evaluated for in vitro antioxidants potential using DPPH (1,1-diphenyl-2-picryl-hydrazyl) assay and also agar-well diffusion method were used for antimicrobial potential. In vitro antioxidants inhibition potential were measured through spectrophotometer at various concentration (500 to 62.5µg/mL) prepared in standard solvent. Among all extracts aqueous fraction showed IC50 = 2.9 ± 0.05mg/mL maximum potency towards stable DPPH much closer to standard control acarbose IC50 = 2.61 ± 0.01mg/mL. The antibacterial activity results indicated that all fractions found active against both strains (gram positive and gram negative) of bacteria. In various extracts only the aqueous fraction extracts showed excellent inhibition potential against Staphylococcus aureus and Escherichia Coli. While dichloromethane fraction extracts were found active only with gram negative strain. Thus the Cerastium fontanum extracts possess much higher inhibition potential then standard available antibiotics in the market.

The objectives of the study were to determine the acetylcholinesterase (AChE) inhibitory activity and antioxidant activity in the selected Sri Lankan medicinal plants. AChE inhibitory activity of the selected medicinal plant extracts was determined using the Ellman’s method. The antioxidant activities were determined by four in vitro methods namely DPPH assay, FRAP assay, NO assay and TBA acid method.  The contents of total polyphenols and flavonoids were determined quantitatively.Out of the ten selected medicinal plant extracts Abrus precatorius, Centella asiatica, Strychnos nux-vomica and Ricinus communis showed IC50 values < 200 µg/mL for AChE inhibitory activity. A high antioxidant activity was shown in the extracts of Cardiosprmum halicacabum, Centella asiatica and  Ricinus communis in  the four selected antioxidant assays.  The total polyphenol content and total flavonoid content was in the range of 0.55-7.30 mg/g DW and 19.08±0.29-1283.08± 0.09 µg/gDW. The extracts of A. precatorius, C. asiatica, S. nux-vomica and R. communis are deserved to be as potent sources of AChE inhibitors as well as natural antioxidants. Considering the complex multifactorial etiology of Alzheimer's diseases, these plant extracts would be apt candidates for the development of novel pharmaceutical agents in the management of Alzheimer's diseases.

In this paper explored the pharmacognostical profile of gymnema sylvestre and its anti-hyperglycemic activity has been documented well with references. The importance of the species in Ayurveda has been highlighted. The bioactive components like gymnema sylvestre has a variety of secondary metabolites, including oleanane, gymnemic acid, gymnemasides (A-F), gymnemic acid (IXVIII) homologue, gymnemic acid A1 and its derivatives, triterpenoidsaponin, al has been clearly includedin the review kaloid (Conduritol-A), polypeptide (Gurmarin), and gymnemasaponins. This study has provided the groundwork for developing a pharmacognostical profile of medicinal plant growers and collectors. The goal of this review study is to provide a regional profile of the indigenous knowledge system for medicinal plant usage and cultural behaviors related to healing. This study aids in the identification of novel ethnomedicinal plant species in the study region, which may lead to the development of new medicines. The plant toxicity test results indicated that it may be used as an alternative to diabetes therapy with no or little adverse effects. This study confirms the conventional use of indigenous plant-derived natural medicine for treating diabetes mellitus. The study also highlighted the efficacy of "Ayurveda" which is an ancient tradition, used in some parts of India. This ancient concept should be carefully evaluated in the light of modern medical science and can be utilized partially if found suitable. I hope that this kind of research will be useful to future researchers as per their needs.
