Theosteoporosis, which is occurred after menopause, is a kind of metabolic bone disorder. It develops when the bone mass begins to decrease radically and its main symptoms are the bone fracture and the height-shortening. This thesis aims at what effects the Phlomis umbrosa will have for the prevention of the osteoporosis in the SD-rat that is caused by the ovariectomy. The 24 female white rats, after their ovaries are removed, were divided into the Normals, the Control group, Phlomis umbrosa Administrated group. After then, for 8 weeks, D.W to the normals and the control, and the Phlomis umbrosa(46 mg/100 g) to the Phlomis umbrosa group were given in the mouths of them. After 8 weeks the rats were sacrificed. And the weight, albumin, AST, ALT, total-cholesterol, triglyceride, P, Ca, T4, estradiol, the weight of the femur, the amount of tibia ash, the area of trabecular bone, the thickness of trabecular bone were measured. The serum analysis shows that the total cholesterol of the Phlomis umbrosa Administrated group reduced remarkably, compared to that of the control group. AST, ALT, ALP, T4 of Phlomis umbrosa group were decreased, but not in distinct measure. Estradiol of Phlomis umbrosa group increased substantially compared to that of the control group, but albumin, triglyceride, Phosphorous, calcium of the group showed the tendency to increase, but not so remarkably. The histological observation shows that the area and the thickness of (trabecular bone), the number of osteoclast of the Phlomis umbrosa groups increased significantly compared to those of the control group. Conclusions: The above experiment shows that Phlomis umbrosa has the prevention effect by supplying estradiol.

The roots of Phlomis umbrosa (Turcz.) (Phlomidis Radix) have been traditionally used to treat cold, reduce swelling and staunch bleeding. Four iridoids (1 - 3 and 5) and six phenylethanoid derivatives (4, and 6 - 10) were isolated from the roots of P. umbrosa. A simple, sensitive, and reliable analytical HPLC/PDA method was developed, validated, and applied to determine 10 marker compounds in Phlomidis Radix. Furthermore, the isolates were evaluated for cytotoxic and anti-oxidant activities as well as DPPH-HPLC method. Among them, compounds 4 and 6 - 9 displayed potent anti-oxidant capacities using DPPH assay with $IC_{50}$ values of $27.7{\pm}2.4$, $10.2{\pm}1.1$, $18.0{\pm}0.8$, $19.1{\pm}0.3$, and $19.9{\pm}0.6{\mu}M$, and compounds 6, 8, and 9 displayed significant cytotoxic activity against HL-60 with $IC_{50}$ values of $35.4{\pm}3.1$, $18.6{\pm}2.0$, and $42.9{\pm}3.0{\mu}M$, respectively.

'SogDan(續斷)' is one of the crude drugs used mainly as a tonic and analgesic. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of SogDan from Korea, the anatomical characteristics of Phlomis umbrosa Turcz. and Phlomis koraiensis Nakai were studied. As a result, it was clarified that SogDan from Korea was the root of Phlomis umbrosa.

Objectives : This study aimed to review the change in the origin of Sokdan(續斷) by diachronically analyzing literature data from Korea and China. Methods : Literature records describing the origin(synonyms, location of production, description) of Sokdan were collected, records were divided into periods. The main contents were included in the results, and original texts were edited and summarized in the table. Results : Sokdan, whose leaves resemble Jeoma(苧麻)(SJ), was first recorded in 《Xinxiubencao(新修本草)》, and described in detail in 《Bencaotujing(本草圖經)》 during the Tang and Song dynasties in China. In modern times, SJ was assumed to be genus Phlomoides or Lamium; however, records of the plant have decreased. Finally, SJ was not included in the 《Pharmacopoeia of the People's Republic of China》 as Sokdan. However, 《Diannanbencao(滇南本草)》, 《Diannanbencaotushuo(滇南本草圖說)》, 《Zhiwumingshitukao(植物名實圖考)》 described Sokdan of dian(滇). It was assumed genus Dipsacus. From the 1950s onwards, Sokdan is described in the literature as a member of the genus Dipsacus. In korea, SJ was recorded in 《Hyangyakjipseongbang(鄕藥集成方)》 and 《Dongeuibogam(東醫寶鑑)》 during the Joseon dynasty. In modern times, the genera Phlomoides and Lamium were mostly recorded as the origin of Sokdan. Conclusions : Several species have been described as Sokdan over the years in China, but since the 1950s, the genus Dipsacus was noted as the origin of Sokdan. In Korea, SJ was used in the past, thus Sokdan was recorded as P. umbrosa in 《The Korean Herbal Pharmacopoeia(KHP)·1985》. However, 《KHP·1998》 referred to P. umbrosa as Hansokdan and D. asperoides as Sokdan.

As a result to amplifying 12 samples of 'Sok-dan' through an random amplified polymorphic DNA (RAPD) method using eighteen DEC and URP primers, distinct band forms enabling discrimination of Phlomus umbrosa and Dipsacus asperoides were observable in the UBC 320 primer, UBC 367 primer, UBC 385 primer, UBC 414 primer, UBC 423 primer, URP 3 primer, URP 5 primer and URP 9 primer. The polymorph result amplified with a random primer was evaluated through Gelcompar II, showing a result dividable into two groups. The divided groups were the dried sample group of Dipsacus asperoides and the group of Phlomis umbrosa. In order to recognize the distinction between Dipsaci Radix types, the genetic variation of 'Sok-dan' produced domestically and imported was evaluated through RAPD, and the potential to distinguish these in forms of dried medicine was identified, presenting a method to authentification of Phlomis umbrosa and Dispacus asperoides.

The purpose of this study was to investigate the effects of extract mixture of C. wilfordii and P. umbrosa (IPLUS-CWPU) on bone growth in 4-week old young male SD rats. To confirm the effect of IPLUS-CWPU, we measured the length of bone growth plate, the ratio of proliferative zone to the length of growth plate and the expression level of insulin-like growth factor, IGF-1. The IPLUS-CWPU treatment shows a significant increase of tibial and femoral growth plate and the ratio of proliferative zone in growth plate. Especially, the length increased by 13.9% and 25.3% in the tibia and femur, respectively, in the high-dose group compared to the normal group. Moreover, the expression of IGF-1 gene in liver was upregulated in IPLUS-CWPU treated groups. These results indicated that IPLUS-CWPU administration could increase the proliferative zone of bone growth plate in early developmental stage by upregulation of IGF-1 gene.

Cynanchum wilfordii and Phlomis umbrosa Turcz. are known to contain isoflavone, a representative phytoestrogen. This study was performed to determine whether the extract mixture of C. wilfordii and P. umbrosa Turcz. would induce an estrogenic effect in ovariectomized rats. The extracts were administered to the ovariectomized rats at 30, 60, 120 mg/kg per day for 4 weeks, respectively. They showed no estrogenic effect, which was indicated by the decrease in uterus wall thickness as well as the increase in body weight and the level of cholesterol and triglyceride. The extracts also had no effect on the concentrations of estrogen and growth hormone in the serum. However, the increase in alkaline phosphatase activity, which leads to protection against the bone loss caused by ovariectomy, was noted on administration of the extract. Therefore, it seemed that the extracts of C. wilfordii and P. umbrosa Turcz. had no estrogenic effect in rats.
