Objectives : We studied Effects of Hagocho(prunella vulgaris L.), Gamgook(chrysanthemum indicum L.) and Galgeun(pueraria Radix) aqua-acupuncture on the hyperlipidemic rat. methods : We investigated lowering lipid effect, oxidative capacity, concentration of TNF-${\alpha}$, IL-6, Leptin and histological consideration in hyperlipidemic rat. Forty male Sprague-Dawley rats weighing about 400g were divided into 5 groups of control, Ⅰ: Hagocho (prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Gokji aqua-acupuncture, Ⅱ: Hagocho(prunella vulgaris L.)+Gamgook (chrysanthemum indicum L.) and Joksamri aqua-acupuncture, Ⅲ: Hagocho(prunella vulgaris L.)+Galgeun(pueraria Radix)and Gokji aqua-acupuncture and Ⅳ: Hagocho (prunella vulgaris L.)+Galgeun(pueraria Radix) and Joksamri aqua-acupuncture. Results : Contents of plasma ${\beta}$-lipoprotein, contents of IL-6, TNF-${\alpha}$ and leptin, Plasma triglyceride and glucose, plasma total cholesterol and LDL-cholesterol, liver total cholesterol, liver triglyceride, plasma and liver TBARS, free fatty acids showed a tendency to decrease in the aqua-acupuncture groups compared to those of control group. The activities of GOT and GPT showed no significantly different in all treatment groups. Values of super oxide dismutase, glutathione peroxidase and catalase activity showed a tendency to increase in the aqua-acupuncture groups. Histological consideration of heart, kidney and liver in the aqua-acupuncture groups showed slight vasodilation and fat accumulation compared to those of normal rat. Conclusions : These results indicated that prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix aqua-acupuncture at gokji(LI11) and Joksamri(ST36) suppressed adipose tissue mass and lipid peroxidation and increased antioxidant system in hyperlipidemic rat.

This study was designed to investigate the effects of antioxidant and antibacterial activities of water, ethanol and methanol extracts from root, stem and flower stalk of Hagocho (Prunella vulgaris). The solvent extract yields from root were higher than those from stem and flower stalk, and water extract showed the highest extraction yield against ethanol and methanol extracts. The contents of total phenolic and flavonoid in ethanol extract were significantly higher in stem extract compared with those of root and flower stalk. In the case of water and methanol extracts, however, the contents were the highest in flower stalk. The electron donating ability and reducing power in all test groups were significantly increased in a dose-dependent manner, and antioxidant activities were the highest in methanol extract. In extracts from different parts of Hagocho, the antioxidant activity was the highest in flower stalk followed by stem and root. ABTS radical scavenging ability of water and methanol extracts was above 50% at $100\;{\mu}g/mL$ concentration. Antibacterial activities did not show significant differences depending on parts of Hagocho. However, antibacterial activity of ethanol extract was higher than those of other extracts.

Effects of prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix on plasma lipid composition and histological consideration were investigated in hyperlipidemic rats. Concentration of plasma ${\beta},-lipoprotein$ showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However these values were showed not significantly different from control group. Concentration of plasma FFA in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups showed a lower values compared to control group and concentration of plasma FFA of prunella vulgaris L. and pueraria Radix treatment group showed a lower values than prunella vulgaris L. and chrysanthemum indicum L. treatment group. Concentration of plasma glucose and triglyceride showed a tendence to decrease in prunella vulgaris L., chrysanthemum indicum L. and pueraria Radix treatment groups. However plasma glucose values showed not significantly different from control group. Plasma total cholesterol concentration showed a low and HDL-cholesterol concentration showed a high in prunella vulgaris L. and pueraria Radix treatment group. However LDL-cholesterol concentrations were not significantly different in treatment groups. Histological consideration of heart, liver and kidney in prunella vulgaris L. and pueraria Radix treatment groups showed a good features in fat accumulation condition than those of other treatment groups. However in the condition of high fat accumulation in tissues, heart, liver and kidney were showed a slight congestion and a bashed cell nucleus.

The aim of the present study was to investigate the antioxidant activities of methanol extracts from whole plant, flower stalk and stem of Hagocho (Prunella vulgaris). Content of total phenolic compound was the highest in flower stalk (77.1 mg/100 g) and those of others were below 54.0 mg/100 g. Flavonoid contents was the highest in stem (36.1 mg/100 g) compared to other samples. Electron donating ability of Prunella vulgaris was activated at over 70% in all samples at $500{\mu}g/mL$ concentration, especially, the activity was the highest (92.1%) in flower stalk extracts. Reducing power showed similar tendency to electron donating ability, which was significantly higher flower stalk ($0.3{\sim}1.9$), whole plant ($0.2{\sim}1.6$) and stem ($0.2{\sim}1.5$). Hydroxyl radical was scavenged over 80% in $100{\mu}g/mL$ concentration and was not significantly different between parts. Antioxidant activity in $\beta$-carotene-linoleic acid system was $47.5{\sim}84.6%$ when $1,000{\mu}g/mL$ methanol extracts was added to reaction mixtures, and flower stalk showed the highest activity. Ability of ABTs cation decolorization from Prunella vulgaris was activated over 50% in all samples when $250{\mu}g/mL$ of methanol extracts was added to reaction mixtures and $500{\mu}g/mL$ were the most suitable concentration for its activation. Nitric oxide scavenging activity was lower under 20%, but its activity was significantly higher in flower stalk than other parts. The results indicate that flower stalk from Prunella vulgaris has potent antioxidant activities.
