Inhibitory effects of 130 medicinal plants on hyaluronidase activity were analyzed. The medicinal plants are clinically used as herbal medicines for korean traditional prescriptions. Six out of the 130 herbal medicines exhibited more than 50% of inhibition on hyaluronidase activity by their total methanol extracts with 5mg/ml as a final concentration. The active total methanol extracts were prepared from cortex of Acantbopanax gracilistylus, lignum of Caesalpinia sappan, radix of Glycyrrhiza uralensis, radicis cortex of Morus alba, herba of Prunella vulgaris, and radix of Sanguisorba officinalis. These active total methanol extracts were sequentially fractionated with dichloromethane, ethyl acetate, n-butanol, and then water. Among the solvent-fractionated extracts, the butanol fractions of Acantbopanax gracilistylus and Glycyrrhiza uralensis with 1 mg/ml as the final concentration exhibited more than 50% of inhibition on hyaluronidase activity, and the other fractions with the same concentration did less than 20% of inhibition.

This study is an attempt to investigate the effects of the water extracts of the whole plants of Prunella vulgaris (Labiatae) and Thesii chinense (Santalaceae) on the acute toxicity, the activities on central nervous system and the diuretic action. The acute toxicities shown by $LD_{50}$ were estimated to be more than 3000 mg/kg p.o. and 1,000 mg/kg s.c. in the extracts of Prunellae Herba and Thesii Herba, respectively, in mice. The extracts at a dose of 2,000 mg/kg p.o. did not show any activities on central nervous system, i.e, sedative, analgesic, hypothermic and anticonvulsant actions. The urination in rats was increased by 45.5% and 57.6% when 100mg/kg of each of the extracts were given orally. The results obtained revealed that the water extracts possessed weak diuretic actions without any of central nervous system activities. Furthermore, it is considered that the potassium in the extract may play a role in the diuretic action.

Several kinds of medicinal plants are used as diuretics in folk medicines and oriental drugs. The diuretic action of water extracts of the ten kinds of crude drugs, such as Pachyma hoelen $R_{UMPHIUS}$ Zea mays L., Akebia quinata $D_{ECAISNE}$, Alisma orientale Juzepezuk, Atractylodes koreana $N_{AKAI}$, phytolacca americana L., Achyranthes japo-nica $N_{AKAI}$, Juncus decipiens $N_{AKAI}$, Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$ was examined in mouse and compared with aminophylline as a control the following results were obtained. The urine volume was found to be remarkably increased by the Pachyma hoelen RUMPHIUS, Phytolacca americana L., Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$, moderately increased by the Akebia quinata $D_{ECAISNE}$, Achyranthes japonica $N_{AKAI}$ and Juncus decipiens $N_{AKAI}$, and slightly increased by Zea mays $L_{ENNE}$, Alisma orientale $J_{UZFPEZUK}$ and Atractylodes koreana $N_{AKAI}$.

식물체의 부위별 및 추출용매에 따른 생리활성을 비교하고자 하고초를 뿌리, 줄기 및 꽃대로 구분하고 에탄올, 메탄올 및 물 추출물에 대한 항산화 및 항균 활성을 비교 분석하였다. 추출 수율은 뿌리 추출물이 다소 높은 경향을 보였으며, 물 추출물은 에탄올 및 메탄올 추출물에 비해 6~11배의 높은 수율을 나타내었다. 총 페놀화합물 함량은 에탄올 추출물에서는 줄기에서, 메탄올과 물 추출물에서는 꽃대에서 유의적으로 높게 나타났으며, 플라보노이드 함량은 뿌리에 비해 줄기와 꽃대에서 전반적으로 높은 함량을 나타내었다. 각 추출물의 전자공여능 및 환원력은 모든 실험군에서 농도 의존적으로 증가하였고, 용매별 추출물에서는 메탄올 추출물의 활성이 유의적으로 높게 나타났으며, 부위별 추출물에서는 꽃대> 줄기> 뿌리의 순으로 높은 전자공여능 및 환원력을 보였다. 또한 메탄올 추출물과 물 추출물의 ABTS 라디칼 소거능은 $100\;{\mu}g/mL$의 저농도에서도 꽃대, 줄기 및 뿌리에서 모두 50% 이상의 소거능을 보였다. 하고초 각 부위별 추출물의 항균활성을 측정한 결과 꽃대, 줄기 및 뿌리간의 유의적인 차이는 보이지 않았으나, 열수 추출물에 비해 에탄올 및 메탄올 추출물에서 다소 높은 항균활성이 관찰되었는데, 특히 뿌리와 줄기의 $1,000\;{\mu}g/mL$ 농도에서는 유의적으로 높은 항균활성이 확인되었다. 이상의 결과로 볼 때, 하고초의 꽃대를 이용한 에탄올 및 메탄올 추출물은 식품의 저장성 향상에 이용가치가 높을 것으로 기대된다.

Joins (SKI 306X) is now clinically used for the treatment of osteoarthritis (OA). In previous reports, Joins a natural herbal product extracted from three herbs Clematis Radix. Trichosanthes Radix and Prunella Flos, was shown to have good analgesic and anti-inflammatory effects in several in vivo models. e.g., acetic acid-induced pain, carrageenan-induced paw edema and adjuvant-induced arthritis.

Objectives : Categorized as 'cheongyeol' herbs, Herba Prunellae, Flos Lonicerae and Radix Scutellaria have been proven to have effect on degenerative brain disease, cerebrovascular disease and brain tumor because of their anti inflammation, antioxidant, or anticancer effects. In this study, we studied activity against reactive oxygen species and anti inflammation effect of these three 'Cheongyeol' herbs. Methods : We measured each herb's yield of ethanol extracts, phenolic contents and activities against DPPH, hydroxyl radical and superoxide anion. Also through 6-hydroxydopamine (6-OHDA) induced oxidative damage in SH-SY5Y human neuroblastoma cell line, we measured antioxidant effect and NO activity of the three herbs. From the three herbs, we chose Prunella Herba, which showed the highest antioxidant effect, and studied its cell survival rate and anti inflammation effect through COX-2 and iNOS. Results : All three herbs showed significant results, and especially Prunella Herba showed significant effect on phenol contents, antioxidant effect on various active oxygen and antioxidant, and anti inflammation effect through cell line. Conclusions : Further study of the origin concept of 'cheongyeol' and research into specific mechanisms and role in treatment of cranial nerve disease, seems warranted.
