  • This experiment was conducted to select optimum hydroponic systems for clean and mass production for shoot and root of Echinacea. E. purpurea and E. angustifolia. were grown at 5 different kinds of hydroponic systems; NFT, modified NFT, DFT, aeroponics, and Ebb & Flow for 150 days. The lowest photosynthetic rate and transpiration rate were in Ebb & Flow system in E. purpurea and E. angustifolia at 120 days after transplanting. The shoot fresh and dry weight were high in aeroponic and DFT system of E. angustifolia and in aeroponic and NFT system of E. purpurea at 150 days after transplanting. The root fresh and dry weight of both species were the highest in aeroponic system and next to modified NFT system. They were increased in NFT and Ebb & Flow system for the root length and in aeroponic system for the number of tillering. The results demonstrate that aeroponic system was the most effective for enhancement shoot and root biomass of Echinacea spp. in hydroponics.

  • To evaluate the anti-diarrheal potential of the leaves of Bauhinia purpurea Linn., investigations were performed on different animal models e.g. castor oil induced diarrhea in rats and gastrointestinal motility test by using charcoal meal. In both the models the ethanolic extract of the leaves showed significant activity when compared to control group. The group treated with standard anti-diarrheal agent also showed significant activity comparing with control. Thus this study establishes the efficacy of Bauhinia purpurea Linn. Leaves as an anti-diarrheal as claimed in folklore.

  • The present study aimed to determine the possible mechanisms of the peripheral antinociception of the aqueous extracts of Dicranopteris linearis (AEDL), Melastoma malabathricum (AEMM) and Bauhinia purpurea (AEBP) leaves in mice. Briefly, the antinociceptive profile of each extract (300, 500, and 1000 mg/kg; subcutaneous (s.c.)), was established using the abdominal constriction test. A single dose (500 mg/kg) of each extract (s.c.) was pre-challenged for 10 min with various pain receptors' antagonists or pain mediators' blockers and 30 min later subjected to the antinociceptive assay to determine the possible mechanism(s) involved. Based on the results obtained, all extracts exerted significant (p < 0.05) antinociceptive activity with dose-dependent activity observed only with the AEMM. Furthermore, the antinociception of AEDL was attenuated by naloxone, atropine, yohimbine and theophylline; AEMM was reversed by yohimbine, theophylline, thioperamide, pindolol, reserpine, and 4-chloro-DL-phenylalanine methyl ester hydrochloride; and of AEBP was inhibited by naloxone, haloperidol, yohimbine and reserpine. In conclusion, the antinociceptive activity of those extracts possibly involved the activation of several pain receptors (i.e. opioids, muscarinic, ${\alpha}_2$-adrenergic and adenosine receptors, adenosine, H3-histaminergic and $5HT_{1A}$, dopaminergic receptors).

  • Rehmanniae radix preparata is the root of Rehmanniae glutinosa Liboschitz var. purpurea Makino which has been classified into Scrophulariaceae. Rehmanniae radix preparata has been used for the treatment of diabetes, for the relief of the pain, and for the anti-oxidative action. In this study, the effect of the aqueous extract of Rehmanniae radix preparata on lipopolysaccharide-induced inflammation was investigated by using 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), Western blot, prostaglandin E2 immunoassay, and nitric oxide (NO) detection in mouse BV2 microglial cells. In the present results, the aqueous extract of Rehmanniae radix preparata suppressed prostaglandin E2 (PGE2) synthesis and nitric oxide production by inhibiting the lipopolysaccharide-stimulated expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) mRNA and protein in mouse BV2 cells. These results show that Rehmanniae radix preparata exerts anti-inflammatory effect probably by suppressing of COX-2 and iNOS expressions.

  • In this study, the DPPH free radical scavenging activity, antimicrobial effects, growth inhibition and cytotoxicity of herb extracts were determined to screen alternative antibiotics. Hot water extracts of 10 species herbs (Origanum vulgare, Monarda didyma, Echinacea purpurea, Ocimum basilicum, Mentha piperita, Melissa officinalis, Thymus vulgaris, Stevia rebaudiana, Rosmarinus officinalis, Matricaria recutica) were used. DPPH free radical scavenging activity of all herb extracts was ranged from 31.4-49.9%, and significantly great activties were found at Rosmarinus officinalis, Origanum vulgare and Matricaria recutica (P<0.05). Hot water extracts of monarda didyma, origanum vulgare, thymus vulgaris and rosmarinus officinalis showed greater antimicrobial activities compared to others. Additionally, those four extracts represented relatively low cytotoxicity compared to others. As a result, it was found that Origanum vulgare and Rosmarinus officinalis which possessed great antioxidant and antimicrobial activity with less cytotoxicity. So these two herb extracts can be used as an alternative of antibiotics for organic farming.

  • The changes in the contents of GABA ($\gamma$-aminobutyric acid) and free amino acids (FAA) were analysed by HPLC in soybean fermented with Monascus pilosus IFO 480, which showed the highest GABA-producing ability among the five different strains. The significant increase (p<0.05) of GABA was observed in Monascusfermented soybean (MFS) with an average 4.5-fold increase of FAA. The contents of GABA (78.5 mg /100 g dry weight, dw) and FAA (5458.5 mg /100 g dw) were enhanced in MFS compared with unfermented soybean (31.5 mg /100 g dw, 1634.0 mg/100 g dw, respectively) during 30 days fermentation at $30^{\circ}C$. Acidic amino acids (i.e., glutamic acid and aspartic acid) in FAA files were found in large quantities (837.0 mg /100 g dw, 580.5 mg /100 g dw, respectively). Moreover, the sum of essential amino acids of MFS (1681.5 mg /100 g dw) at 20 days fermentation increased by 3.6 times compared with that of the control (469.0 mg /100 g dw). The results indicate that Monascus-fermentation have great potential for the enrichment of GABA and free amino acids in soybean.
