Korean folk medicine 'Bong Seon Wha Dae' has been used to cure constipation and acute gastritis by meat. The botanical origin of the crude drug has not been studied pharmacogostically. To clarify the botanical origin of 'Bong Seon Wha Dae', the morphological and anatomical characteristics of Impatiens species growing in Korea, I.e. I. Balsamina L., I. Noli-tan-gere L., I. Textori Miq. And I. textori Miq. for. pallenscens Hara were studied. As a result, 'Bong Seon Wha Dae' was proved to be the stem of I. Balsamina L.

To study Antimicrobial activities of wool and silk dyed by Impatiens balsamina extract with concentraion and times of dyeing, its leaf and stem was extracted by water. Wool and silk dyed by extracts were their microbial inhibition activities against Staphylococcus aureus KCTC 1928. The more concentration, The more times of dyeing their microbial inhibition activities were increased. Fabrics dyed by leaf estracts were higher microbial inhibition activities than fabrics dyed by stem extracts. Silk dyed by the leaf and stem extracts were higher microbial inhibition activities than wool dyed by the leaf and stem extracts. the more dye uptake, microbial inhibition activities of dyed fabrics were incresed.

Plants produce extrafloral nectar (EFN), liquid of carbohydrates to protect themselves against various insect herbivores through attracting natural enemy, ants, wasp and parasitoids, so EFN production is well known as one of indirect defense mechanisms. In many plants, EFN production is increased or induced when plants are attacked and damaged by insect feeding, whereas there are some plants whose EFN production is not altered or even decreased upon insect attack. The feeding types (chewing or sap feeding) of insects attacking plants also affect EFN production. The objective of this study was to examine how insect herbivore alters production of extrafloral nectar of Impatiens balsamina. Two different types of herbivores, leaf chewing and sap feeding insects, Spodoptera litura and Impatientinum impatiens respectively, are utilized. Plants were mechanically damaged by making holes on leaves with Jasmonic acid (JA) and regurgitate of S. litura added on. Two different densities of aphids were confined on leaves. The results of the study was that mechanical damage and JA or regurgitate addition did not affect EFN production in I. balsamina. Aphid feeding, regardless of density treated, decreased EFN production. The results of the study suggest that production of extrafloral nectar of Impatiens balsamina can be changed by insect feeding, and the effects of insect feeding can depend on the type of insects.

The in vitro antibacterial activity against antibiotic-resistant Propionibacterium acnes of kaempferol isolated from the Impatiens balsamina alone and in combination with erythromycin or clindamycin antibiotics was investigated. The antibiotic combination effect against antibiotic-resistant P. acnes was studied by checkerboard test. Kaempferol and quercetin demonstrated antibacterial activities against P. acnes. Minimum inhibitory concentrations (MICs) for both compounds were ${\leq}32\;{\mu}g/ml\;and\;{\leq}64{\mu}g/ml$ for clindamycin-sensitive and -resistant P. acnes, respectively. The four combination formulations (kaempferol and either erythromycin or clindamycin; quercetin and either erythromycin or clindamycin) exhibited a synergic inhibition of P. acnes growth. The combination of kaempferol with quercetin showed an indifferent effect. The combination of clindamycin with kaempferol or quercetin showed a greater synergic effect than that of erythromycin with kaempferol or quercetin. Thus, these combinations demonstrated the potential to treat acne.

To study antimicrobial activities of Impatiens balsamina, its leaf and stem was extracted by methanol and water. The extracts were tested their microbial inhibition activities against several microorganisms, staphylococcus aureus KCTC 1928, Escherichia coli KCTC 1116, Klebsiella pneumoniae KCTC 2690, Trichophyton mentagrophytes KCTC 6316. The methanol extract and water extract of the leaf and stem didn't show the inhibition effect on E. coli but showed the inhibition effect against the ohter 3 species of the microorganisms tested. The extract of leaf showed higher inhibition than the extract of stem. And the methanol extract showed higher inhibition than the water extract.

The purification of the MeOH extract from Impatiens basamina by repeated column chromatography led to the isolation of one new tetrahydronaphthalene (1), together with eleven known compounds (2 - 12). The structure of the new compound (1) was determined by spectral data analysis ($^1H$ and $^{13}C$-NMR, $^1H-^1H$ COSY, HSQC, HMBC, NOESY, and HR-ESI-MS). Isolated compounds (1 - 12) were evaluated for their inhibitory effects on NO production in LPS-activated murine microglial BV-2 cells and their effects on NGF secretion from C6 glioma cells. Compounds 3, 7, and 10 reduced NO levels in LPS-activated murine microglial cells with $IC_{50}$ values of 26.89, 25.59, and $44.21{\mu}M$, respectively. Compounds 1, 5, and 9 upregulated NGF secretion to $153.09{\pm}4.66$, $156.88{\pm}8.86$, and $157.34{\pm}3.30%$, respectively.

Korean folk medicine 'Mul Bong Seon' has been used to cure hypertension and a toxicide. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'Mul Bong Seon', the morphologial and anatomical characteristics of the leaves of Impatiens species growing in Korea, i.e. I. balsamina, I. noli-tangere, I. textori, I. textori forma. pallescens were studied. As a result, it was clarified that 'Mul Bong Seon' was the leaf of Impatiens textori and Impatiens textori forma. pallescens.

The effects of simulated acid rain (SAR) on fatty acid composition and biochemical defense responses of plant was investigated. Garden balsam (Impatiens balsamina L.) was exposed to four pH levels (5.6, 4.0, 3.0, 2.0) of SAR and placed in the growth chambers for 2 weeks. SAR drastically inhibited chlorophyll content of garden balsam. The level of $H_2O_2$ was significantly increased by SAR. As pH levels decreased from 5.6 to 2.0, the ratio of unsaturated to saturated fatty acids of garden balsam was increased. Changes of three major polyamines (putrescine, spermidine and spermine) of garden balsam leaves were observed. All of the polyamine contents were increased with SAR. Catalase activities of the plant affected by SAR were increased as the pH decreased. The results indicate that the application of SAR generates oxidative stresses from the garden balsam and retards the plant growth significantly. A biochemical protect mechanism might be activated to neutralize the oxidative stresses generated through SAR.

To investigate the effects of simulated acid rain (SAR) on growth and biochemical defense responses of plant, garden balsam (Impatiens balsamina L.) was subjected to four levels of SAR based on pH (5.6, 4.0, 3.0, 2.0) and placed in the growth chambers for 2 weeks. SAR drastically inhibited both height and dry weight of garden balsam. The content of total carotenoid was tended to decrease, but the level of malondialdehyde was significantly increased by SAR. As the pH levels decreased from 5.6 to 2.0, the content of dehydroascorbate and oxidized glutathione of the plant were significantly increased. The enzyme (superoxide dismutase, ascorbate peroxidase etc.) activities of the plant affected by SAR were increased as the pH decreased. The results indicate that garden balsam may receive oxidative stresses by the application of SAR and by which the plant growth can be significantly retarded. A biochemical protective mechanism might be activated to nullify the oxidative stresses generated through SAR.
