The present study aims to detect the rare flavonoids isolated from the leaves of Persicaria glabra. The known flavonoids: quercetin (1), isorhamnetin (2), avicularin (3) and new one isorhamnetin-3-O-α-L-(6''-E-p-coumaroyl)-rhamnoside (4) were identified by HPLC, UV, IR and NMR. P. glabra has used traditionally for its analgesic, anti-inflammatory and anti-rheumatic properties. To find out the ingredients responsible for the efficiency of this plant, we have used to study the anti-microbial and anti-inflammatory activities of different extracts.

Centella asiatica (Linn.) Urban (Umbelliferae) which is also known as 'pegaga' is highly consumed and eaten raw as 'ulam' in Malaysia. C. asiatica is used in traditional medicines to treat various health conditions such as rheumatism, inflammation, syphilis, skin diseases and diarrhoea. Various reports exhibited that the crude extracts and isolated bioactive compounds of C. asiatica possessed a broad range of pharmacological activities such as anti-oxidant, anti-diabetic, anti-tumor, wound healing, anti-microbial, anti-inflammatory, immunomodulatory, hepatoprotective and memory enhancing properties. The pharmacological validation on anti-microbial and immunomodulatory of C. asiatica is very limited and several existence review papers related for this plant had not been focused for both activities. This review therefore attempts to combine the existing literature to offer immense scope for researchers engaged in validation of the traditional claims and bioactivities of this plant related with anti-microbial and immunomodulatory potential.

This studies were performed to develop a Korean traditional folk liquor namely Gangha-ju has been prepared at Bosung district in Korea, and manufacturing conditions and anti-oxidation activity and anti-microbial activity of Gangha-ju were investigated. Ethyl-alcohol 20% and 30% Gangha-ju were brewed with glutinous rice wine, distilled liquor and 6 herbs of ginger, cinnamon, etc. Chemical and physical properties of 30% Gangha-ju were acidity 0.22, pH 4.31, amino acidity 3.26, transmittance 59 and conductivity $911\;{\mu}s/m$, and 20% Gangha-ju were 0.43, 4.20, 6.26, 62 and $924\;{\mu}s/m$. Volatile flavor compounds of ethyl alcohol, acetic acid, butanol, n-amyl alcohol, iso-pentyl alcohol, ethyl acetate, butyl acetate, acetaldehyde and furfural were detected, and main aroma compounds of Gangha-ju were isopentyl alcohol and ethyl acetate. Anti-oxidation activity by DPPH method was evaluated 31.32%, and nitrite scavenging effect was 31.79%. Anti-microbial activity against several microorganisms was pronounced strong activity over a wide range of test organisms, and Leuconostoc mesenteroids and Salmonella Ttyphimurium, Staphylococcus epidermidis were found to be more sensitive to Gangha-ju than Escherichia coli and Aspergillus flavus.

An isolate of Streptomyces rochei synonym was found to produce antibiotics with narrow anti-microbial spectrum against Streptococcus and Xanthomonas sp. Among the antibiotic complex produced by the strain, the main active compound was isolated, and its physico-chemical properties and biological activities were investigated. Molecular weight of the compound was determined to be ${[M+H]}^+$ 797 (FAB-MS). UV, $^1H \;and\;^{13}C$ NMR, and IR spectra suggested that the compound is a kirromycin-like aurodox group antibiotic. However, the anti-microbial spectrum of the main compound was slightly different from that of kirromycin. In addition, it was newly found that kirromycin showed a selective anti-microbial activity against Streptococcus pyogenes and phytopathogenic Xanthomonas sp.

Skin patch test and antibacterial properties of the reaction products between poly(hexamethyl biguanide) hydrochloride and trimethylol melamine on textile fabrics were examined. Antibacterial activities of anti-microbial agent treated samples are very good. The reduction ratios against four kinds of colonies are 99.9 % after repeated laundering ten times. Skin patch test results for anti-microbial agent treated samples are almost-negative by Hi-scope judgement and macroscopical judgement.

A new phenol and hydrazide derivatives were obtained for the first time from the C. giganteawhite by silica gel column chromatography. The structure of the isolated compounds was identified by UV, IR NMR and MS. C. gigantea was scientifically reported for several medicinal properties viz. analgesic, antimicrobial and cytotoxic. In this screening work, anti-microbial activity of test compounds was found to be active against all organisms. Additionally, anti-inflammatory activity of the test groups has reduced the thickness of edema of the hind paw compared to the control group.

The purpose of this study was (1) to demonstrate the anti-microbial properties of 4-hexylresorcinol (4HR) loaded silk mat and (2) comparison of bone formation between 4HR incorporated silk mat and collagen membrane. Anti-microbial properties of 4HR incorporated silk mat was done after sterilization of silk mat (autoclaving and ethylene oxide gas). For the evaluation of bone formation, bilateral bony defects (size: 8 mm) were prepared in the parietal bone of the rabbits (n=10). 4HR incorporated silk mat (size: $10{\times}10mm$) was applied on the right defect. For the comparative purpose, the same size of commercial collagen membrane was applied on the left defect. The anti-microbial properties of 4HR incorporated silk mat were maintained after sterilization process. When compared bone mineral density and bone volume, there was no statistically significant difference between groups at 4 weeks and 8 weeks after operation (p>0.05). In conclusion, 4HR incorporated silk mat could be autoclaved without concern of anti-microbial properties loss. In addition, 4HR incorporated silk mat showed similar bone regeneration to collagen membrane. Therefore, 4HR incorporated silk mat might be considered for the application of open membrane technique.

Ginseng is described as the "King of all herbs, "Man-root" or "Root of heaven" and regarded as the most powerful herbal remedy, particularly grown in Korea, China, Japan, Vietnam, and North America. It has been in existence for a long time. The most demanded herbal cure, Ginseng, principally the root, has long been employed in traditional Asian medicine. The extent of availability of bioactive combinations and their impact on the body differs between American and Asian ginseng. Asian ginseng, also known as Panax ginseng, has a more calming influence and is more advantageous than American ginseng, such as Panax quinquefolius. The pharmaceutical aspect of development and extraction with diverse morphological properties is examined. Saponins, glycosides, carbohydrates, polyacetylenes, amino acids, vitamins, volatile oil, enzymes are all present in the Phyto-content of Ginseng. Ginsenosides are saponins that are constituents of the triterpenoid dammarane and have anticancer, anti-cardiovascular, anti-microbial, anti-obesity, anti-inflammatory, and antioxidant properties. Ginseng, in particular, has the possibility to help with microbial invasion, inflammatory processes, oxidative stress, and diabetes. It developed nanoparticles and nanocomposite film technologies as novel drug delivery platforms for cancer, inflammation, and neurological illnesses. Furthermore, it offers a range of applications that will be vital for future growth.
