  • 'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

  • 지금까지 우리나라에 자생하는 꿀풀속 식물은 꿀풀(Prunella vulgaris var. lilacina Nakai), 두메꿀풀(P. vulgaris var. aleutica Fernald), 흰꿀풀(P. vulgaris for. albiflora Nakai)이 알려져 있는데, 국내 주요 표본관들의 표본조사를 통하여 P. pinnatifida Pers.가 다수 채집된 바 있음을 확인하였고, 이들 중 전남 신안군 자은도에서의 분포를 재확인하였다. 꿀풀, 두메꿀풀, 흰꿀풀은 식물체 전체의 잎들이 거치가 없거나 미약한 거치가 있는 장타원형임에 비하여 갈래꿀풀의 잎은 매우 심하게 갈라진 열편들로 이루어져 있다. 이에 본 분류군의 국명을 갈래꿀풀로 칭하고 국내 미기록 분류군으로 보고하고자 한다. 갈래꿀풀에 대한 기재, 도해와 함께 갈래꿀풀을 포함한 한국산 꿀풀속 식물에 대한 검색표를 제시하였고, 갈래꿀풀의 분류학적 문제점들을 논의하였다.

하고초 추출물로부터 분리된 Danshensu의 MK-801으로 유도된 사전자극 억제 손상의 회복에 대한 작용 (Danshensu Isolated from Prunella vulgaris var. Lilacina Attenuates MK-801-induced Prepulse Inhibition Deficits in Mice)

  • Schizophrenia is a severe psychiatric disorder and characterized by positive symptom (i.e., delusions, hallucinations), negative symptom (i.e., lack of emotion, social withdrawal), and cognitive impairment. Previously, we reported that the ethanolic extract of Prunella vulgaris var. lilacina attenuated the MK-801-induced schizophrenia-like behaviors such as prepulse inhibition (PPI) deficits and cognitive impairment in mice. The aim of the present study was to investigate whether danshensu isolated from P. vulgaris var. lilacina attenuates MK-801-induced sensorimotor gating dysfunction (PPI deficits), hyperlocomotion, and memory impairment in mice. Acute administration of danshensu (1, 3, or 10 mg/kg) significantly ameliorated the MK-801-induced PPI deficits in the acoustic startle response test. We also observed that the impaired recognition memory induced by MK-801 was attenuated by danshensu (1 mg/kg) in the novel object recognition test. However, danshensu failed to reverse the MK-801-induced hyperlocomotion in the open-field test. Collectively, the present results indicate danshensu would be an active agent for treating neuropsychiatric disorders such as schizophrenia.

  • The potential antioxidant activities of different fractions from Prunella vulgaris var. lilacina were assayed in vitro. Among several fractions, n-BuOH fraction showed the highest 1,1-di[henyl-2-picrylhydrazyl (DPPH) free radical scavenging ($IC_{50}=0.50{\mu}g/mL$). The results of 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity and ferric reducing antioxidant power (FRAP) assay showed the concentration dependency and n-BuOH fraction appeared a better result than the other fractions at the same concentrati on in this study. Moreover the total phenol and flavonoid contents of n-BuOH fraction contained the highest level. Additionally, correlation analysis indicated a high correlation between the antiradical activity and the total phenolic and flavonoid contents (p < 0.001). It suggests that n-BuOH fraction obtained from the 70% EtOH crude extract of Prunella vulgaris var. lilacina has wide potential for use as a source of antioxidant material.

  • Three known ${\alpha}$-amyrin triterpenoids, ursolic acid (1), $2{\alpha},3{\alpha}$-dihydro xyurs-12-ene-28-oic acid (2) and euscaphic acid (3), and ${\beta}$-amyrin triterpenoid, $3{\beta}$-hydroxyolean-5,12-diene (4), and ${\alpha}$-spinasterol (5) have been isolated from the fractionated n-butanol extracts of the spikes of Prunella vulgaris var. lilacina, guided by DNA topoisomerases I and II inhibitory activities and cytotoxic activity against human cancer cells. Their structures were elucidated on the basis of spectroscopic and chemical methods. Compound 4 exhibited significant cytotoxic activity against human colon adenoblastoma (HT-29), and 5 showed DNA topoisomerase I and II inhibitions.

  • Ursolic acid was isolated from Prunellae Herba (Prunella vulgaris var. lilacina) and identified by direct comparison with an authentic sample. A method of analysis for the evaluation of ursolic acid was developed based on extraction of ground plant material, followed by quantitative determination using capillary gas chromatography of the TMS derivative. Quantitative analysis by GC after derivatisation under mild silylating conditions showed 0.31% ursolic acid in 20 samples collected throughout regions of Korea while no ursolic acid was detected in the samples of the whole plant of Thesium chinense, a substitute for Prunellae Herba in southern regions of Korean peninsula.

  • 16종의 한약재 및 약용식물류의 열수 추출물에 대한 흡광도, 총페놀화합물 및 플라보노이드 함량과 이들의 항산화 효과를 분석하였다. 추출수율은 단삼이 $35.49\%$로 다른 시료에 비하여 월등히 높았으며 pH는 $4.00\~5.92$의 범위로 산성 pH에 더 가까웠다. 방향족 화합물의 함량을 검색하고자 $250{\mu}g/mL$농도의 시료로 280 nm에서 흡광도를 측정한 결과 꿀풀이 2.872로 가장 높았으며 엉겅퀴와 산사육, 산조인은 0.5이하의 낮은 흡광도를 나타내었다. 갈색화 반응 생성물의 흡광도를 측정한 결과도 유사한 경향을 나타내어 꿀풀의 경우 1.312로 가장 높은 값을 다음은 옥수수수염 (0.917), 금물초(0.725) 순이었다. 총 페놀 화합물의 함량은 꿀풀이 $5.07{\pm}0.05mg/100g$으로 다른 시료에 비하여 월등히 높은 함량이었고 플라보노이드의 함량은 단삼에서 $4.82{\pm}1.16\;mg/100g$으로 다른 시료에 비하여 약 2배 정도 높은 함량이었다. 대부분의 시료에서 농도가 증가함에 따라 전자공여 효과도 높아지는 경향을 보였는데 산조인, 산수유, 단삼은 $1000{\mu}g/mL$의 농도에서 $90\%$ 이상의 전자공여 효과를 나타내었다. 환원력도 전자공여능과 유사한 경향이었으나 BHT와 비교할 때 유의적으로 낮은 환원력을 나타내었다. 아질산염 소거능은 $500{\mu}g/mL$의 농도에서 $50\%$ 이상의 소거효과를 나타낸 시료는 꿀풀과 금물초 2종에 불과하였으며 $1000{\mu}g/mL$의 농도에서는 산조인, 산수유, 감국, 꿀풀, 금물초, 오가피, 단삼, 울금이 $50\%$ 이상의 소거효과를 나타내었다. 꿀풀의 경우 전 농도에서 다른 시료들에 비하여 유의적으로 높은 아질산염 소거효과를 나타내어 $250{\mu}g/mL$에서는 $59.62{\pm}1.573\%,\;1000{\mu}g/mL$에서는 $80.58{\pm}0.300\%$의 소거효과를 보였다.
