  • Extraction of the Effective Components in Salvia paohsingensis and Their Contents Determination

    Ying ZHAO;Qi LIU;Meng WANG;Li ZHANG;

    [Objective] To discuss the methods for the extraction of effective components from the roots of Salvia paohsingensis C. Y. Wu, and to research whether S. paohsingensis could be used a substitute for Salvia miltiorrhiza Bunge. [Method] Reflux extraction, Soxhlet extraction and ultrasonic extraction were used for the extraction of the effective components from S. paohsingensis; and their results were compared. Contents of the extracted components were detected by HPLC. Relevant components in cultivated S. miltiorrhiza were also researched. [Result] As for the fat-soluble components, ultrasonic extraction was significantly superior to reflux extraction and Soxhlet extraction due to the characteristics of low temperature and high efficiency. As for the water-soluble components, Soxhlet extraction for 4 h was the optimal. Content analysis showed that the fat-soluble components in S. paohsingensis were relatively high. Among them, content of tanshinone IIA met the requirements in Chinese Pharmacopoeia; but the content of water-soluble components was relatively low. [Conclusion] S. paohsingensis had certain medicinal value. Whether it could be a substitute for S. miltiorrhiza still needed further research.

    Xiao LUO;Xingguo ZHANG;Xiaozhi LONG;Yanchen YANG;Qian WANG;

    [Objective] To study the variation of the polysaccharide content of domestic high quality Ophiopogon japonicus tubers at different developmental stages, to determine the quality characteristics and to provide a scientific basis for the GAP quality control and integrated resource development and utilization of O. japonicus. [ Method] Plant tubers collected from Hangzhou O. japonicus and Sichuan Ophiopogon japonicus were graded in accordance with the fresh tuber grading standards. Through microwave kill enzyme -50 ℃ and constant temperature drying, the polysaccharide content of O. japonicus tubers was determined by phenol-sulfuric acid colorimetric method. The law of correlation between the average biomass and the polysaccharide content of tubers at different developmental stages was analyzed using SPSS17.0 statistical software. [Result] The polysaccharide content of Hangzhou O. japonicus and Sichuan O. japonicus tubers at different developmental stages ranged from 24.36% to 41.09% and from 21.54% to 40.29%, respectively. With the increase of developmental stage, the accumulation of photosynthetic products was significantly positively related to the polysaccharide content of O. japonicus tubers (P<0.001). The regression equation was written as y1=7.496ln(x) + 36.45 (R2=0.993) for Hangzhou O. japonicus, and y2=12.68x+19.22 (R2=0.997) for Sichuan O. japonicus. [Conclusion] the accumulation of photosynthetic products in O. japonicus tubers at different developmental stages is closely related to the content of secondary metabolites polysaccharide. It is scientific to divide the domestic high quality O. japonicus tubers by the traditional grade specifications.

    Shizhen CAI;Jing LI;Xi LI;Yuanzhi PAN;Chong YE;

    [Objective] To investigate the effects of different light conditions on the growth and photosynthetic characteristics of Sanicula lamelligera Hance. [Method] One-year-old sowing seedlings of S. lamelligera were transplanted in 5 different site conditions, including bamboo forest, metasequoia forest, forest edges and open space. Three years later, the growth indexes and physiological indexes of plant leaves were measured. [Result] S. lamelligera plants grew well to the east of metasequoia forest, in open space and in bamboo forest with larger leaf area index and higher net photosynthetic rate and grew commonly in metasequoia forest with smaller leaf area index and lower net photosynthetic rate. But to the west of metasequoia forest, the growth of S. lamelligera was inhibited with the minimum leaf area index and higher net photosynthetic rate. [Conclusion] S. lamelligera is a kind of typical undergrowth vegetation growing close together under trees in woods and forests, which is suitable to be planted in ventilated and euphotic land parcels to the east of metasequoia forest.

  • Comparison of the Moisture Retaining Abilities between Hyaluronic Acid and Cactus Extracts

    Hui LIU;Lei HE;

    [Objective] To find new and cheap additives of cosmetics which are non-toxic and cost low. [Method] Cactus extracts were selected as the humectant of cosmetics in order to take the place of traditional hyaluronic acid. Formula system with 0.02% hyaluronic acid and that with different proportions of cactus extracts (0.15%, 0.30%, 0.45%) were designed. Biochemical measurement and human trial were carried out in order to verify the moisture retaining abilities of cactus extracts. [Result] Adding 0.15% cactus extracts had better moisture retaining effects than the control (adding 0.02% hyaluronic acid); adding 0.15%-0.45% cactus extracts showed no significant increasing effects of moisture retaining, and there were no statistical significance. [Conclusion] The market price of hyaluronic acid was 36-60 times higher than that of cactus extracts, but the moisture retaining ability of cactus extracts was superior. Besides, the dosage of cactus extracts was small in cosmetics, which could be easily accepted by the consumer. Therefore, cactus extracts could be applied in cosmetics as a humectant.

    [Objective] To research the optimal conditions for the extraction of capsaicinoids from Sanming Capsicum annuum L. by microwave-assisted method, and to study on the removal technology of spicy taste from Capsicum Red pigments. [Method] Effects of solvent, microwave power, extraction time and solid-liquid ratio on the extraction rate of capsaicinoids were investigated by single factor test. [Result] The optimal extraction condition for capsaicinoids by microwave-assisted method was as follows: low power (200 W), 3 min extraction time, and 1∶15 solid-liquid ratio with VEthanol∶VAcetone=1∶1. Under this condition, the extraction rate of capsaicinoids was 52.5%. And the optimal condition to remove spicy taste from Capsicum Red pigments was also obtained. The removal of the spicy taste was relatively ideal under the conditions of 2.0 h soaking time, 15% NaOH concentration, 50 ℃ soaking temperature, and crude extracts (including 99.2% capsaicinoids and Capsicum Red pigments): 15% NaOH =1∶10 (g/mL). Under these conditions, spicy taste could be significantly removed. The yields and extraction rate of capsaicinoids were 2.237 mg/g and 52.5%, respectively. Capsaicinoids were colorless needle crystal with 99.2% purity and 63.5-65 ℃ melting point. [Conclusion] In-depth research on the extraction method of capsaicinoids could improve the yield and purity of capsaicinoids and could provide broad market space for the development of capsaicinoids in China.

  • Protective Effects of Triptolide on Podocytes and Renal Tubular Epithelial Cells

    Dong ZHOU;Jihong CHEN;Lu ZHANG;Wei SUN;Ningning XIONG;

    Tripterygium wilfordii Hook.f is a medicinal plant having anti-inflammatory and immunosuppressive effects. The therapeutical effect of T. wilfordii on renal diseases is closely related with repairing intrinsic kidney cells. Triptolide (T10) is the major component of monomer found in T. wilfordii, which could protect podocytes by maintaining the activated state of Rho/ROCK pathway, suppressing the expression of p-38MAPK activated by C5b-9 and inhibiting cell apoptosis. In addition, T10 could interfere in presenting antigen of renal tubular epithelial cells and provide the stimulating signal for T cells to block the activation of antigen-specific CD4+ T cells, which is considered to be one of mechanisms for treatment of autoimmune kidney diseases. The protective effect of triptolide on renal intrinsic cells could provide a new direction for further development and utilization of T. wilfordii.
