Objective : Gardeniae Fructus (GF) has bitter and cold nature. Thus, it has been traditionally prescribed in processed form roasted with ginger juice for patients with a weak stomach. This study investigated the effects of processed GF in tert-butyl hydroperoxide (tBHP)-treated gastric epithelial cells. Methods : Processed GF was made by applying 40% ginger juice or 10% ethanol for 24 h and then roasting at 150℃ for 5 minutes. Apoptosis was determined by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Mitochondrial membrane potential (MMP) was monitored by flow cytometry using the membrane permeable fluorescent dye Rh123. Protein expression was measured by Western blot analysis. Results : Cell viability was reduced by tBHP and restored by ethanol extract of GF (GFE). In the TUNEL assay, it was found that cell death by tBHP was due to apoptosis, and GFE had an anti-apoptotic effect. Processed GF roasted with ginger juice showed the best anti-apoptotic effect. Processed GF also inhibited MMP loss and restored tBHP-induced changes in expression levels of apoptosis-related proteins. Increased ROS production and GSH depletion after tBHP treatment were significantly reduced by processed GF. In addition, tBHP-induced activation of mitogen-activated protein kinase (MAPK) was inhibited by processed GF. Conclusion : These results demonstrate that the processed GF is able to protect gastric epithelial cells from oxidative stress-induced cell death with antiapoptotic and antioxidant activity. In addition, it shows that the processing of GF, which have been traditionally used for gastrointestinal protection, partially have scientific validity.

Objective : Gardeniae Fructus (GF) is the ripe fruit of Gardenia jasminoides Ellisa with a bitter taste and cold properties. Ingredient compounds including geniposide are known to have anti-inflammatory, antioxidant, and neuroprotective effects. The purpose of this study was to investigate the neuroprotective effect of GF on tBHP-induced PC12 cells. Methods : Cell viability was measured by the MTT assay, and apoptosis was determined by the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The expression level of each protein was monitored by Western blot analysis, and reactive oxygen species (ROS) were analyzed using DCFH-DA. Results : In PC12 cells, tBHP induced cell death through apoptosis with caspase activation and PARP inactivation. Cells treated with tBHP showed an increase in intracellular ROS and depletion of GSH. Pretreatment with GF prevented tBHP-induced apoptosis, reduced ROS, and increased GSH. GF also maintained increased Nrf2 expression in the presence of tBHP. Phosphorylation of JNK and p38 MAPK was increased by tBHP, whereas phosphorylation of ERK was decreased. GF restored changes in ERK and p38 phosphorylation, but not JNK phosphorylation. Conclusion : These results indicate that GF has neuroprotective effects through anti-apoptotic and antioxidant effects mediated by regulation of Nrf2 expression and phosphorylation of ERK and p38. It also demonstrates the potential use of GF as a source of antioxidant and neuroprotective substances.

Geniposide and its related iridoid compounds have been used in traditional herbal medicine for thε treatment of Jaundice hepatic diseases and various inflammatorys. For the purpose to increase trandsdermal absorption, the hydrolyzed products of Gardeniae Furctus were identified and assayed of active ingredients and investigated trandsdermal absorption and anti-inflammatory effects. Geniposide was hydrolyzed to genipin by ${\beta}-glucosidase$ and it was suggested that genipin was more suitable form than geniposide for transdermal absorption by its lipophilic property. Using Franz type diffusion cell and the skin of hairless mouse, the permeation rate of hydrolyzed products and their emulsion preparation were determined. Genipin have more increased absorption ratio through the skin of hairless mouse than geniposide. Also, the emulsion of hydrolyzed products of extracts showed higher permeability than that of nonhydrolyzed preparations. After 9 hours $280.85\;{\mu}g/cm^2$ of genipin was absorbed and $193.52\;{\mu}g/cm^2$ in case of geniposide. The Js of geniposide and genipin were $26.27{\pm}4.11\;{\mu}g/cm^2/hr$ and $40.35{\pm}5.04\;{\mu}g/cm^2/hr$ respectively. After carrageenan injection, the swelling was increased repidly to 24 hr and maintained as plateau. but emulsion group weer reached about 2.5 mL and the swelling decreased successively form 24 hr to 72 hr. The anti-inflammation effects of extracts and hydrolyzed products emulsion were increased with significant difference with control group after 24 hr, 48 hr and 72 hr. In carrageenan induced edema, inhibition of swelling was increased in case of hydrolyzed product emulsion compare with nonhydrolyzed group at 24 hr, 48 hr and 72 hr after swelling. In histological study, the anti-inflammatory effects of hydrolyzed products were remarkable at 48 hr and 72 hr compare with nonhydrolyzed. Hydrolyzed products of Gardeniae Fructus extracts containing genipin would be a suitable preparation to increase the transdermal absorption and anti-inflammatory effects.

Gardeniae Fructus (GF) is a fruit of Gardenia jasminoides Ellis (Rubiaceae) which has been used in traditional medicine. It contains not only geniposide but also resveratrol, a kind of stilbene as a natural antioxidant. In this study, we investigated physiological activities of GF extracts by measuring electron donating ability (EDA), nitrite scavenging ability (NSA), super oxide dismutase (SOD)-like activity and inhibitory effect of tyrosinase activity (ITA). As a solvent, it was extracted with water, 50 and 100% ethanol using microwave. At the concentration of 6 mg/mL, EDA was the highest at 50% ethanol extract but the lowest at 100% ethanol extract, $96.43{\pm}0.25%\;and\;77.06{\pm}0.22%$ respectively. NSA showed the strongest activity at 50% ethanol extract like EDA (6 mg/mL: $75.26{\pm}0.28%$). ITAs were below 20% in all samples and their activities reduced according to increasing concentration. Likewise, SOD-like activities decreased with increasing concentration of extracts in all samples. In conclusion, GF extracts showed low SOD-like activities and ITAs but EDAs and NSAs were fairly high; especially EDA of 50% ethanol extract (6 mg/mL) was high as those of 0.1 and 1% L-ascorbic acid. Therefore the results suggest that GF extracts may be useful as potential sources of natural antioxidants.

Objective : The purpose of this study was to analyze the effects of HwangRyunHaeDok-Tang and combinations of constituent herbs on the arterial contraction. Methods : In order to investigate the effects Scutellariae Radix. Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus, in which one of them, two of them, and all of them, were used to exam. Results : The results were summarized as follows; 1. HwangRyunHaeDok-Tang significantly inhibited the contraction of artery induced by Norepinephrine(NE). However the atonic effect was slightly blunted when the vascular endothelial cell was removed. No significant change in the atonic effect of HwangRyunHaeDok-Tang was found when $_L-NNA$ was used as a preliminary treatment. These results indicate that the vascular atonic effect by HwangRyunHaeDok-Tang is slightly dependent on the endothelial cell, and that the HwangRyunHaeDok-Tang works directly to the vascular smooth muscle in creating the vascular atonic effect. 2. The pretreatment of HwangRyunHaeDok-Tang extract significantly inhibited the contractile response to additive application of $Ca^{2+}$ in the strips which were contracted by NE in $Ca^{2+}$-free solution. 3. HwangRyunHaeDok-Tang extract increased the contraction of arterial smooth muscle induced by KCl. Therefore, it can be concluded that HwangRyunHaeDok-Tang may block the NE-receptor or receptor-operated $Ca^{2+}$ channel. 4. It was determined that Scutellariae Radix, Coptidis Rhizoma and Phellodendri Cortex among the ingredients of HwangRyunHaeDok-Tang have a vascular atonic effect. In addition, those ingredients plays a role in strengthening the atonic effect by working with other herbal medicines. Gardeniae Fructus causes the blood vessel to contract. but it does not influence the atonic effects of other herbal medicines. However Gardeniae Fructus tends to inhibit the vascular atonic effect of Phellodendri Cortex. Conclusion : Based on the above results, it can be said that HwangRyunHaeDok-Tang can be applied to cure hypertension considering those three herbs have significant effects of relaxation.
