Objective : Herbal medicinal mixture (JMB) are consisted of Caryophylli Flos, Aucklandiae Radix, and Angelicae Dahuricae Radix. Each of these herbal medicines has studied on anti-aging effect in vitro. So this study was conducted to investigate efficacy and potency of JMB extract on dermal anti-aging and whitening. Methods : The JMB was extracted at room temperature by 80% ethanol. Collagenase and elastase inhibition activity in JMB ethanol extract were determined at 10, 50, 100, 500, 1000 mg/ml concentrations by colorimetric method. The toxic range of JMB ethanol extract was evaluated using MTT assay. Also, The inhibitory effect of JMB ethanol extract on tyrosinase activity and melanin contents in mouse melanoma cell line (B16F10 cell) was identified at 50, 100, 200 ㎍/㎖ levels by spectrometric assay. In each analysis, EGCG (epigallocatechin gallate) and Kojic acid were used as positive controls, respectively. Results : The elastase and collagenase inhibitory activity of JMB ethanol extract increased dose dependently. Also, The MTT assay showed that JMB, up to 400 ㎍/㎖ concentration, exhibited no toxic effect to the B16F10 cell. And following the JMB ethanol extract treat, cellular melanin contents and tyrosinase activity were dose-dependently decreased compared to those of control. Conclusion : These results suggest that JMB ethanol extract has effects to inhibitory activity on dermal wrinkle enzyme and melanogenesis. Therefore, JMB has applicable benefits for development of materials or products to have whitening and anti-aging functions on skin.

This studies were examined in orther to investigate the object and the method of animal experimental papers on medicinal herbs of cancer therapeutic activities from the reported 23 literatures containing anti-cancer effects of medicinal herbs. The results were obtained as follows: 1. The oriental medicinal therapies on cancer were Pujeung(扶正法), Kuesa(祛邪法), Pujeungkuesa(扶正法邪法). 2. The experimental medicinal herbs of cancers therapy were 103 species, which was used for experimental cancer single or combine. Among then, Houttuyniae herba, Polyporus, Manitis squama, Evodiae fructus, Aucklandiae radix and Pharbitidis semen were effective for cancer treatment, while Houttuyniae herba inhibited tumor cells, but not normal cells. Also, Evodiae fructus, Aucklandiae radix and Pharbitidis semen showed strong cytoxicities on 20 different tumor cell lines, whereas Saururi herba seu rhizoma showed cytoxicity against HT-29 cell, melanoma, SK-MEL-5 cell, and Anemarrhenae rhizoma against ovarian tumor cell only, and Schizonepetae herba against HT-29 cell line only with a potent inhivitory activities. 3. P815 cell, Yac-1 cell, Sarcoma 180 cell, K 562 cell, and SNU-1 cells were frequently used as experimental cancer therapy.

The purpose of this study was to introduce the differential standard of the types of Angelicae Pubescentis Radix. We established the classificatory standard according to the external and internal morphology and the physicochemistrical pattern for the four types of Aucklandiae Radix. The results follow: 1. At the external shape, Angelica pubescens f. biserrata has rising lenticel and dark brown surface, Its section is light gray and its xylem is yellow gray. Aralia continentalis has big stem mark in upper portion, its section has no dense tissue with yellow gray. Heracleum hemsleyanum has dark brown surface and little lenticel, its cortical layer is white yellow and xylem is isabella and powdered. 2. At the internal shape, Angelica pubescens f. biserrata has phloem with half of the root and rare vessel. Aralia continentalis has phloem with two-thirds of the root and it has broad cutting and putting vessel that formed 1-2 row. Heracleum hemsleyanum also has phloem with half of the root and wide scattered latex tube and many large vessel. 3. At the TLC pattern, Heracleum hemsleyanum has remarkable dark spot at $R_{f}$ 0.23 on the sulphuric acid color pattern test, but others have faint. 4. At the HPLC pattern, all samples have generally patterns. But Angelica pubescens f. biserrata shows diminutive continentalic acid content and the peak at Rt 20.278min comes out on Heracleum hemsleyanum, but do not come out on Aralia continentalis and Angelica pubescens f. biserrata. Heracleum hemsleyanum has remarkable peak at Rt 20.278min, but shows no peak at Rt 29.023min unlike Aralia continentalis or Angelica pubescens f. biserrata. Also Aralia continentalis and Angelica pubescens f. biserrata show one remarkable peak at Rt 29.023, but Heracleum hemsleyanum do not show. Consequently, Aralia continentalis and Angelica pubescens f. biserrata are comparable whit continentalic acid content and Heracleum hemsleyanum is comparable with the peak at Rt 20.273 and Rt 29.023. So it is thought that content of continentalic acid and the peaks at Rt 20.278 and Rt 29.023 can apply to differentiate a species from other. It is considered the results of this study will be furnished the basis to succeeding studies and it is needed to extensive comparative study for the same genus-degree of relatedness.

Transmembrane protein TMEM16A, which encodes calcium-activated chloride channel has been implicated in tumorigenesis. Overexpression of TMEM16A is associated with poor prognosis and low overall survival in multiple cancers including lung adenocarcinoma, making it a promising biomarker and therapeutic target. In this study, three structure-related sesquiterpene lactones (mecheliolide, costunolide and dehydrocostus lactone) were extracted from the traditional Chinese medicine Aucklandiae Radix and identified as novel TMEM16A inhibitors with comparable inhibitory effects. Their effects on the proliferation and migration of lung adenocarcinoma cells were examined. Whole-cell patch clamp experiments showed that these sesquiterpene lactones potently inhibited recombinant TMEM16A currents in a concentration-dependent manner. The half-maximal concentration (IC50) values for three tested sesquiterpene lactones were 29.9 ± 1.1 µM, 19.7 ± 0.4 µM, and 24.5 ± 2.1 µM, while the maximal effect (E_max) values were 100.0% ± 2.8%, 85.8% ± 0.9%, and 88.3% ± 4.6%, respectively. These sesquiterpene lactones also significantly inhibited the endogenous TMEM16A currents and proliferation, and migration of LA795 lung cancer cells. These results demonstrate that mecheliolide, costunolide and dehydrocostus lactone are novel TMEM16A inhibitors and potential candidates for lung adenocarcinoma therapy.
