As a part of studies on the quality control of crude drug preparation drinks, ginseng saponins were identified by HPLC. Ginsenoside-Rb1 was determined quantitatively by HPLC. Ginsenoside MeOH/H2O(65:35:10, v/v) on Si-gel plate. Ginsenoside-Rb1 content determined by HPLC on Lichrosorbtract drinks was 57.5-70.4% compared to the content in the red ginseng extract.

The investigation is involved with the development of the new method of decoction preparation in order to prevent the loss of volatile oil from crude drugs. Volatile oil in crude drug containig volatile oil ranged from 1 to 2.2% in content. Volatile oil content in crude drung prescription which main component is a crude drug containing volatile oil was $0.11{\sim}0.39\;ml$. It was found that traditional method of decoction preparation has caused to lose almost all of the volatile oil. Application of method of Pharmacopoea (Kp II) for the preparation of decoction prevented the loss of volatile oil from one half to two-third of its content. The method of Pharmacopoea to which air condenser was attached could completely prevented the loss of volatile oil from the preparation.

Objectives : The aim of this study is reviewing the past legal definition and regulations, to provide basis for the future desirable direction of Korean herbal pharmaceutical industry and national herbal drug policies. Methods : We reviewed how concept of herbal medicinal preparation has been utilized and changed along with various national laws and regulations. And this study also reviewed problems related herbal medicinal preparation policies. Results : Since 1990s, especially inauguration of Korea Food & Drug Administration (KFDA) at 1998, the concept of crude drug preparation has constantly expanded and distorted the scope of herbal medicinal preparations. This resulted in decline of herbal medicinal preparation industry. Conclusions : It means policies related herbal medicinal preparation which was driven steadily during this decade have lost their consistency. Also, it restricted the various medical options which can guarantee people's health rights.

As a part of studies on the quality control of crude drug preparation (So-Shi-Ho-Tang), index components of Glycyrrhizae Radix were identified by TLC and quantified by HPLC. Specific red spot (Rf=0.47) was identified in acid hydrolysate of glycosidic fraction on silica gel plate with benzene/ethyl acetate (1 : 1, v/v). The content of glycyrrhizin was determined by quantification of glycyrrhetinic acid by HPLC on ${\mu}-Bondapak\;C_{18}$ column with $MeOH/H_2O/HAc$ (78 : 19 : 3, v/v). Its recovery rate in the extract granules, compared to the content in the Glycyrrhizae Radix, was $83.3{\pm}0.7%$.

As a part of studies on the quality control of crude drug preparation, So-Shi-Ho-Tang, index components of Scutellariae Radix were identified by TLC and quantified by HPLC. Wogonin and baicalein were identified in ethyl ether fraction on silica gel plate with benzene/ethyl acetate (1 : 1, v/v). The content of baicalin was determined by HPLC on ${\mu}-Bondapak\;C_18$ column with 0.5%-phosphoric acid/acetonitrile (73 : 27, v/v). Its recovery rate in the extract granules, compared to the content in the Scutellariae Radix, was $52.1\;{\pm}\;0.7%$.

From crude drug preparation(Soshiho-Tang) ginseng sapogenins were identified by TLC and $ginsenoside-Rb_1$ was determined quantitatively by HPLC. Panaxadiol, pandaxatriol, acid-hydrolysates of ginseng saponin, were identified by TLC with benzene/acetone(4 : 1, v/v). Rf values of which were measured as 0.26 and 0.14, respectively. The content of $ginsenoside-Rb_1$ was determined by HPLC on $Lichrosorb-NH_2$ column with $CH_3CN/H_2O/n-BuOH$(80 : 20 : 10, v/v). Its recovery rate in the extract granules, was as relatively low as $19.8{\pm}1.4%$ compared to the content in raw red ginseng.

For the quality control of crude drug drink preparations, methods for identification of cinnamon components and quantitative determination of cinnamic acid were established. Cinnamon components were identified by TLC with benzene/ethyl acetate (1:1, v/v) on silica gel plate by spraying p-anisaldehyde-sulfuric acid. Cinnamic acid contents were determined at UV 280 nm by HPLC on $\mu$-Bondapak Cls column with acetonitrile/water/acetic acid (40:60:2, v/v). Recoveries of cinnamic acid in three crude drug drink preparations were between 84.1-90.2% compared to the content of the cinnamon extract.

'Hae Cheong Whan' is a Chinese patent preparation, which has been used for cough in Korea. This preparation consists of 18 powder crude drugs. The microscopic method is very useful to identify individual gradients in powdery mixture because it requires only a small amount of specimens. In this study, it is demonstrated that the microscopic method is very effective for the identification of 18 crude drug ingredients including in 'Hae Chung Hwan'.

GCSB-5 preparation is a purified extract from a mixture of 6 medicinal plants(Acanthopanacis Cortex, Achyranthis Radix, Saposhnikoviae Radix, Cibotii Rhizoma, Glycine Semen Nigra, Eucommiae Cortex) that have been widely used for the treatment of various bone disorders. The aim of this study was to investigate HPLC analysis method and screening of standard compound on Saposhnikoviae Radix for quality standardization of a medicinal crude drug GCSB-5. Standard compound of Saposhnikoviae Radix was decided with cimifugin by isolation and instrumental analysis such as NMR. HPLC analysis method for the simultaneous determination of cimifugin was established for the quality control of the medicinal plants of Saposhnikoviae Radix species, GCSB-5 raw material and preparation. And validation of HPLC analysis methods were conformed for verification of HPLC methods by check to specificity, linearity, intra-day precision, inter-day precision and accuracy following ICH guideline.
