Effects of pungent essential oil from three Chinese herbs on percutaneous absorption of alkaloids from Sophorae Flavescentis Radix / 中国中药杂志

To investigate the effects of essential oil from three kinds of pungent herbs,namely Menthae Haplocalycis Herba,Atractylodis Rhizoma and Cnidii Fructus,on the transdermal absorption in vitro of alkaloids from Sophorae Flavescentis Radix. The modified vertical Franz diffusion cell was used to conduct a transdermal experiment in vitro with the isolated abdominal skin of the SD rats as the transdermal absorption barrier. The effects of such three kinds of pungent essential oil on percutaneous absorption of alkaloids from Sophorae Flavescentis Radix were investigated by determining the content of 6 alkaloids( oxymatrine,oxysophocarpine,N-methylcytisine,sophoridine,matrine,and sophocarpidine) in the transdermal acceptor with ultra-performance liquid chromatography-triple quadruple mass spectrometry( UPLC-TQ-MS) technique simultaneously. With enhancement ratio( ER) as the index,their effects on promoting penetration was as follows: 1% Atractylodis Rhizoma oil > 1% Cnidii Fructus oil > 3% Azone ≈ 3% Atractylodis Rhizoma oil > 5%Atractylodis Rhizoma oil > 3% Cnidii Fructus oil ≈ 5% Cnidii Fructus oil > 3% Menthae Haplocalycis Herba oil > 5% Menthae Haplocalycis Herba oil > 1% Menthae Haplocalycis Herba oil > Blank. The results showed that these three kinds of pungent essential oil could be used as enhancers for alkaloids of Sophorae Flavescentis Radix,providing scientific guidance for improving percutaneous absorption of alkaloids from Sophorae Flavescentis Radix.

Non-invasive treatment to grade 1 essential hypertension by percutaneous laser and electric pulse to acupoint with music: A randomized controlled trial / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study a non-drug therapy for hypertension disease by combining percutaneous laser and electric pulse stimulation to acupoint with music, and to test the efficiency of the combining treatment to grade 1 essential hypertension.</p><p><b>METHODS</b>A total of 174 patients with grade 1 essential hypertension were randomly assigned to 3 groups with a random number table after Chinese medicine (CM) syndrome differentiation: the photoelectric and musical treatment group (Group 1, with a self-developed multi-mode audio frequency pulse photoelectric therapeutic apparatus), acupuncture group (Group 2), and oral placebo group (Group 3), 58 cases per group. The curative effect of each group was evaluated by the changes of blood pressure and CM syndrome integral before and after treatment.</p><p><b>RESULTS</b>Compared with Group 3, there were significant decrease of blood pressure and CM syndrome integral in Group 1 and Group 2 (P<0.01). Compared with Group 2, Group 1 showed the highest decrease in systolic pressure (P<0.017). The total effective rate of anti-hypertension in Group 1 (91.38%, 53/58) was significantly higher than that in Group 2 (74.13%, 43/58) and Group 3 (18.97%, 11/58, P<0.05 or P<0.01); and that in Group 2 was also significantly higher than that in Group 3 (P<0.01). There were significant difference in the total effective rate of CM syndrome integral in both Group 1 (93.10%, 54/58) and Group 2 (84.48%, 49/58) as compared with Group 3 (17.24%, 10/58, P<0.01), while there was no significant difference between Group 1 and Group 2 (P>0.05).</p><p><b>CONCLUSIONS</b>The multi-mode audio frequency pulse photoelectric therapeutic apparatus, combining music, laser and electric pulse stimulation, is clinically useful for grade 1 essential hypertension. This "three in one" therapy method is non-invasive, easy and simple to handle. It is expected to be popularized as a new alternative treatment.</p>

Evaluation analysis of alkaloids in seed of Sophora flavescens from Shanxi province and exploration of its utilization value / 中国中药杂志

According to the research strategy of resource chemistry of Chinese medicinal materials and Chinese medicinal resources recycling utilization, this study intends to explore the potential resource-oriented utilization value of the seed of Sophora flavescens by contrasting with its kindred plant S. alopecuroides. This study established a rapid UPLC-Q-TOF-MS/MS and UPLC-TQ-MS/MS method to determine the alkaloids in the seed of S. flavescens. Results of UPLC-Q-TOF-MS/MS analysis showed that the alkaloids in the seed of S. flavescens were highly similar with S. alopecuroides.In the determination of 7 kinds of alkaloids, the total content was 11.203 and 15.506 mg•g⁻¹ in the seed of S. flavescens and S. alopecuroides, respectively. The content of oxymatrine, oxysophocarpine and sophoridine is high in the seed of S. flavescens. The results indicated that the seeds of S. flavescens. could be an important material resource to obtain alkaloids.

Analysis and evaluation of alkaloids and flavonoids in flower of Sophora flavescens from Shanxi province / 中国中药杂志

This study intends to explore the potential resource-orientedutilization value of the flower of Sophora flavescents by analyzing alkaloids and flavonoids in the flower of S. flavescens from Shanxi province. This study established a rapid UPLC-TQ-MS/MS method that is used for determination of seven alkaloids and seven flavonoids in the flower of S.flavescens. The different florescences all have the seven detected alkaloids such as cytisine, oxy-matrine, oxy-sophocarpine, sophoridine, N-methylcytisine, matrine, sophocarpine.The total contents of detected alkaloids are as follows: flower buds 1.47%, primal flowers 1.34%, full bloomed flowers 1.17%, faded flowers 1.01%. The top three contents of alkaloids are N-methylcytisine , oxy-sophocarpine and oxymatrine, accounting for about 83% of the total amount of detected alkaloids. All the samples in different florescences have the seven detected flavonoids such as rutin, luteolin, quercetin, isoquercitrin, trifolirhizin, kurarinone, and kushenol I. The total contents of detected alkaloids are as follows: flower buds 495.2 μg•g⁻¹, primal flowers 313.7 μg•g⁻¹, faded flowers 224.2 μg•g⁻¹, full bloomed flowers 193.0 μg•g⁻¹. The content of luteolinis relatively higher than other detected flavonoids, accounting for about 89%-94% of the total amount of detected flavonoids. The results indicated that the flower of S.flavescens could be an important material resource to obtain the resourceful alkaloids. This result can provide scientific basis for resource-oriented utilization and industrial development of the flower of S. flavescens.

Analysis on pharmacokinetics-pharmacodynamics correlation of effective ingredients of Qing'e wan / 中国中药杂志

To study the pharmacokinetics of three active ingredients in Qing'e wan, namely geniposidic acid, psoralen and isopsoralen, in rats, in order to investigate their correlation in the anti-osteoporotic effect. The rats were taken blood from their eye sockets at different time points after being orally administered with raw and salt-processed Qing'e wan. Geniposidic acid, psoralen and isopsoralen in rats plasma were determined by means of UHPLC-MS/MS to draw the concentration-time curve. The proliferation rate of osteoblasts was taken as the pharmacodynamic index, and determined by MTT method to draw effect-time curve. In comparison between the effect-time curve and the concentration-time curve, the blood concentrations of geniposidic acid and psoralen were close to the peak when the cell proliferation rate reached its peak, indicating a good correlation between them. The peak blood concentration of isopsoralen was slightly lagging behind the peak of efficacy. According to the correlation analysis after fitting the effect-time curve and the concentration-time curve, salt-processed Qing'e wan had a better correlation than the raw one. The above experimental results showed that the effect-time curve and the concentration-time curve of geniposidic acid and psoralen had a good correlation, and the correlation of salt-processed Qing'e wan was better than the raw one.
