Antitumor Effects and Acute Oral Toxicity Studies of a Plant Extract Mixture Containing <i>Rhus verniciflua</i> and Some Other Herbs

A novel antitumor agent was developed from six kinds of herbs containing Rhus verniciflua (Rv-PEM01). The components were traditionally established for each formula for traditional medicine. The formula was designed to affect antitumor effect as well as maintain host immune functions. First, we investigated the antiproliferative activities of Rv-PEM01 on human and canine tumor cell lines in vitro, and on antitumor effects using BALB/cAJcl-nu/nu mice in vivo. Acute oral toxicity of Rv-PEM01 was also investigated in vivo in ddY mice. Rv-PEM01 exhibited antiproliferative activities against PC-3 (IC50: 0.328 ± 0.081 mg/ml), A549 (IC50: 0.520 ± 0.070 mg/ml), D-17 (IC50: 0.124 ± 0.037 mg/ml) and MRC-5 (IC50: 0.505 ± 0.058 mg/ml) cells. Luteolin 7-β-D-glucopyranoside and apigenin 7-β-D-glucopyranoside were identified as the main active compounds in Rv-PEM01 by HPLC analysis. The single dose toxicity study of Rv-PEM01 did not result in any deaths or abnor-malities in daily behavior, body weight gain, or anatomical observations at necropsy. Thus, so we could not calculate the 50% lethal dose (LD50) in mice, but it would be higher than 5.0 g/kg. Treat- ment with Rv-PEM01 at a dose of 2.5 g/kg tended to show antitumor activities on mice bearing Colon26 tumors compared with the control group. It was concluded that the formula was a safe antitumor agent with no side effects on mouse physiological function as judged by survival and organ weight.

원산지별 국내 유통 한약재의 이산화황 잔류실태 조사

국내에 유통되고 있는 국산과 수입산 한약재 11종 116건을 대상으로 잔류이산화황에 대한 모니터링을 수행한 결과 108건(93.1%)은 불검출이었고 6건(5.2%)는 이산화황 허용기준치 30 mg/kg을 초과하였고 2건은 30 mg/kg 미만으로 검출되었다. 116건의 이산화황 평균함량은 <TEX>$17.6{\pm}144.2mg/kg$</TEX>이고 최대 검출량은 구기자(1,546.3 mg/kg)이었고 중국산 현호색(66.6%)의 이산화황 검출 빈도가 가장 높게 나타났다. 국내산 한약재는 71건 중 1건(1.4%), 수입산 한약재는 45건 중 7건(15.6%)에서 이산화황이 검출되었고 국내산 1건(36.7 mg/kg)과 수입산 5건(118.1 mg/kg)이 허용기준치를 초과하여 국내산보다 수입산 한약재에 이산화황 잔류량이 많았다. 본 연구를 통해 이산화황 허용기준을 초과하는 부적합율은 다소 낮아지고 있지만 이산화황 허용기준을 초과하는 한약재들 중 일부 한약재에서는 잔류이산화황 함량이 높게 나타났고, 특히 국내산 약재에 비해 수입산 약재는 부적합율이 높게 나왔다. 한약재는 일반적으로 수세 및 가열과정을 거치므로 실제 섭취하는 형태의 탕액에서는 원재료보다 이산화황의 잔류량이 크게 감소하지만 완전히 제거되지는 않으므로 유통되는 한약재의 안전성 확립이 절실히 요구되어진다. 강화된 기준이 정착하여 안전한 한약재가 유통될 수 있도록 수입통관시 특별관리가 요구되며, 보다 적극적인 검사 요주의 품목에 대한 지속적인 잔류이산화황 모니터링이 필요할 것으로 사료된다. This study was carried out to investigate the residual sulfur dioxide residues (<TEX>$SO_2$</TEX>) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of <TEX>$SO_2$</TEX> in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, <TEX>$SO_2$</TEX> contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.

Infrared microspectroscopic identification of marker ingredients in the finished herbal products based on the inherent heterogeneity of natural medicines.

Finished herbal products (FHPs) are preparations made from one or more herbs. The first stage in assuring the quality, safety, and efficacy of FHPs is to identify the herbs in the products. A new simple and quick method is developed in this research to detect the marker ingredients in FHPs. The inherent chemical heterogeneity of herbs and FHPs makes it possible to resolve different ingredients, without any additional separation or labeling, by infrared microspectroscopic imaging. Therefore, multiple marker ingredients in FHPs can be recognized directly and simultaneously by the infrared microspectroscopic identification method. As an example, all six kinds of herbs in Liuwei Dihuang Wan are identified through the following steps: (1) Each herb is characterized by infrared spectroscopic imaging, then the spectra of the main ingredients are calculated by the combination of principal component analysis, independent component analysis, and alternating least squares. (2) One marker ingredient is chosen for each herb. Ten typical pixels, the spectra of which best match the calculated spectrum of the marker ingredient, are selected by partial least squares target. The average spectrum of the typical pixels is taken as the marker spectrum. (3) Correlation coefficients between the typical pixel spectra and the marker spectrum are calculated. The acceptance correlation threshold is determined through the beta distribution function and then validated by positive and negative samples. (4) Using the above marker spectra and correlation criteria, herbs in the model mixture and the commercial product are identified. Good recognition results reveal the potential of the infrared microspectroscopic identification method in the quality control of herbs and FHPs.

Effect of aqueous extracts of several kinds of herbs on human platelet aggregation and expression of P-selectin in vitro

To study the effect of aqueous extract of several kinds of herbs on human platelet aggregation and expression of P-selectin in vitro. Blood was collected from volunteers. Effects of the prepared water extracts of herbs on platelet aggregation were monitored on a Packs-4 aggregometer. The fluorescence intensity of water extracts of Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae on the expression of P-selectin in human platelets of healthy persons was measured with flow cytometry. Out of several herbs investigated, Flos Carthami and Rhizoma Curcumae potently inhibited platelet aggregation after incubation with platelet-rich plasma (PRP) for 15 min. Caulis Spatholobi Flos Carthami and Rhizoma Curcumae inhibited adenosine-5'-diphosphate (ADP) or platelet activating factor (PAF)-induced platelet aggregation in PRP in a dose-dependent manner. In contrast to Flos Carthami and Rhizoma Curcumae, Caulis Spatholobi could not inhibit thrombin-induced platelet aggregation. Despite its inability to inhibit thrombin-induced platelet aggregation in PRP, Caulis Spatholobi had a greater anti-aggregating activity in PRP induced by ADP or PAF. Caulis Spatholobi and Flos Carthami showed significant inhibitory effects on the expression of P-selectin. Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae have potent anti-platelet properties, and their inhibitory actions are mediated via different mechanisms. Caulis Spatholobi inhibited ADP-induced platelet aggregation but not by thrombin, indicating that its mechanism of action might be independent of the thromboxane pathway. The effect of Caulis Spatholobi and Flos Carthami were associated with suppressing the expression of P-selectin.

Analysis and identification of Semen Glycines Nigrae and Semen Pharbitidis by infrared spectroscopy

Semen Glycines Nigrae and Semen Pharbitidis containing a large amount of fats and proteins are commonly used in Chinese herbal medicine. Tri-step infrared spectroscopy was applied to fast analyze and identify the two samples. In the conventional infrared spectroscopy, the samples both have obvious characteristic absorption peaks at 1,745 cm(-1) assigned to the stretching mode of C==O in esters. Furthermore, the two kinds of herbs have the peaks at 1,656 and 1,547 cm(-1) assigned to the amide I and II bands of protein. Obviously, the infrared spectra of herbs demonstrate that protein and fat is the major component in two kinds of herbs, and the relative intensity of the peaks assigned to fat and protein indicate their relative content is different. And the result is consistent with the reported. In the second derivative spectra, Semen Pharbitidis has a peak at 1,712 cm(-1) assigned to the organic acid, however, Semen Glycines Nigrae has not this absorption peak. In addition, in the second derivative spectra, appeared more differences between the two samples in shape and intensity of the peaks. In two-dimensional correlation infrared spectra, the two samples were visually distinguished due to their significant differences in auto-peak position and intensity. In the region of 1,500-1,700 cm(-1), Semen Glycines Nigrae has two autopeaks and Semen Pharbitidis has three autopeaks. In the region of 2,800-3,000 cm(-1), the samples both have two autopeaks, but the position of the strongest autopeak is different. It was demonstrated that the Tri-step infrared spectroscopy were successfully applied to fast analyze and identify the two kinds of samples containing the same major component, and made sure the foundation for future researches.

Simultaneous determination of saponins in Radix Glycyrrhizae, Notoginseng and Ginseng by high performance liquid chromatography

To establish a method for determining five saponins (notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1 and ammonium glycyrrhizinate) in Glycyrrhizae, Notoginseng and Ginseng, the high performance liquid chromatography with diode array detector (HPLC-DAD) method was applied to an Inertsil ODS-SP column (4.6 mm×250 mm, 5 μm) with a mobile phase consisting of acetonitrile-0.05% phosphoric acid in a gradient elution manner. The flow rate was 1.0 mL/min. The column temperature was 30 °C and the detection wavelengths were 203 nm and 237 nm, respectively. The linear ranges were 0.700 0–7.000 0 μg for R1 (r=1.000 0), 0.751 1–7.511 4 μg for Rg1 (r=1.000 0), 0.677 2–6.771 6 μg for Re (r=1.000 0), 0.733 9–7.339 1 μg for Rb1(r= 1.000 0), and 0.540 0–5.399 8 μg for ammonium glycyrrhizinate (r=0.999 9), respectively. In addition, their average recoveries were 100.28%, 105.83%, 104.09%, 99.36% and 98.54%, respectively. The relative standard deviations (RSDs) of precision, reproducibility and recovery were all less than 1.5%. The results indicate that the method is simple, accurate and reproducible so that it can be used for the simultaneous determination of the five saponins in Chinese patent medicines containing the three kinds of herbs.

주왕산국립공원 식물종의 생물계절성

The purpose of this study was to conduct phenology monitoring of forest plant species in Mt. JuWang National Park, thereby establish long-term prediction and management system for species susceptible to climate change, and utilize the result as basic materials necessary for conservation of plant genetic resources in accordance with changes in their growth environment. Global Positioning System coordinates were marked on each indicator species and a specific number ticket was provided to each plant. Changes in their blooming time, time of blossoms falling, time of leaves bursting into life, and time of leaves turning, and time of leaves falling were recorded. Investigation was made once per week from April 10 in 2010 to November 30 in 2011 except for the time period between July and August when investigation was made biweekly. The investigated plants concerned 12 kinds-nine species of trees and three kinds of herbs. According to the result of the penology monitoring of Mt. JuWang National Park, their time of leaves bursting into life, time of leaves turning, and time of leaves falling were largely earlier in 2011 than in 2010. However, it is hard to say that it is due to the factor of climate change. Long-term collection of climate data and continuous monitoring of plant phenology are considered necessary in order to examine correlation between climate change and seasonal change patterns of plants.

Studies on the Time-Varying Effect of Root Morphology and Soil Reinforcement of Two Kinds of Herbs

The roots can significantly increase the soil reinforcement of vegetation, and the fractal theory provides a new perspective for vegetation roots studies. This article applied the Fractal Fox software to calculate the fractal dimension of medicago sativa and cynodon dactylon roots in different growth periods and proved that the two species show fractal characteristics. The conclusions from the analysis are as follows: ①The fractal dimensions of the two plant roots tend to be stable with the increase of growth period; ②The fractal characteristic value of cynodon dactylon root is more significant than medicago sativa root; ③Compared with medicago sativa root, cynodon dactylon root is more effective in increasing the shear strength of soil.

Repellent Effects of Volatile Extracts from Herb Plants against Larvae of Pieris rapae crucivora Boisduval

Environmental pollution and intensive use of toxic chemicals, as well as resistance to pesticides, has forced scientists to find new ways of controlling pests. Numerous substances that repel insects and inhibit eating and egg-laying have been discovered in a variety of plants. The cabbage white butterfly, Pieris rapae crucivora Boisduval, is a serious pest to Brassicaca species such as cabbage, cauliflower and broccoli, and its larvae damage the host plant leaves when feeding. In this study, to develop a botanical insecticide against P. rapae larvae, we assessed the effect of 7 kinds of herb (rosemary, spearmint, eucalyptus, sage, chili pepper, chives and tansy) extracts as feeding repellents against P. rapae larvae. Feeding repellent tests were conducted by placing two cabbage leaf disks on filter paper treated with herb extract or diethyl ether in a box; then a larva was placed between the disks and its preference was observed. The repellent rate of rosemary, spearmint, eucalyptus, sage, chili pepper, chives and tansy was 75%, 72%, 64%, 59%, 40%, 40% and 36%, respectively. These results clarified that of the tested herbs, rosemary and spearmint volatile extracts have a notable feeding repellent effect against P. rapae larvae.

Rocket (Eruca sativa) is an endemic species of the Brassicaceae family which is produced mostly in Mediterranean countries such as Italy, Greece and Turkey. Historical research has shown that rocket was used both as a garden plant and as a kind of herb or spice (Yaniv et al., 1998). According to data from the Turkish Statistics Foundation (TUIK) for the year 2010, Turkey’s rocket production in a year amounted to 4058 tonnes, and was used either raw in salads or cooked in various dishes. Apart from its use in nutrition, it is also used in the health and cosmetics industries as a result of the effectiveness of its phytochemical content. There have been few studies of these beneficial effects or of the mineral content of rocket; therefore, this study was performed as a survey, in which plant samples were collected from the province of Aydin in Turkey and evaluated for mineral content (N, P, K, Ca, Mg, Na, Fe, Cu, Mn and Zn). After chemical analysis of the samples by standard known methods, statistical analysis was performed using the statistics package SPSS 15.0. According to the results of these analyses, the average content of nutrient elements in rocket (Eruca sativa) was found as 4.32% N, 0.25% P, 5.13% K, 2.95% Ca, 0.58% Mg, 799.88 mgkg -1 Na, 350 mgkg -1 Fe, 5.36 mgkg -1 Cu, 40.58 mgkg -1 Mn and 64.86 mgkg -1 Zn. Minimum and maximum values are given together with average values. The aim of this study was to determine the mineral content of samples of rocket (E. sativa) grown by conventional methods in the province of Aydin, and to correlate this to previous studies.

Effective parameters on drying of Hypericum perforatum L. leaves

Drying is one of the most important post harvest processes, which convert decaying products to resistant preparations so that it increases the storage duration and keep product quality (food stuff shelflife). Hypericum perforatum L. is an important kind of herbs, which its Iranian species characterized by high percent of Hyperisin as the most important substance of its leaves and flower. It has an important role in curing some diseases.

A factorial experiment design was laid out in completely randomized design with three replications. In this research, the best treatment for drying time and rate of drying were obtained at temperature of 70°C, air velocity at 1 m/s and 1 cm bed depth. Key words: Hypericum perforatum L., drying time, drying rate.

Corrosive Esophagitis after Ingestion of Chinese Squill

Acute toxicities of Chinese squill (Scilla scilloides), a kind of herb used as a folk remedy to relieve pain in Korea, have rarely been reported. We here present a 59-year-old woman who developed corrosive esophagitis after ingestion of the decocted Chinese squill. Esophagogastroduodenoscopy performed three days after ingestion of Chinese squill showed corrosive esophagitis. She was successfully managed with conservative care including fasting and intravenous hydration with acid suppressants. Corrosive esophagitis after ingestion of Chinese squill has never been reported in English or Korean literature and corrosive esophagitis should be suspected when a patient develops odynophagia after ingestion of Chinese squill.
