      (Comparative study of flavonoids in the leaves of three genera of bamboo(Chinese)
      Q. WEI (Wei Qi), Y. YUE (Yue Yongde)*, F. TANG (Tang Feng), J. SUN (Sun Jia) (*The International Center of Bamboo & Rattan, Beijing 100102, China)

      Chinese J. of Forestry Science 49 (10), 127-134 (2013). Flavonoids in bamboo leaves have free radical scavenging, antioxidant, anti-aging, antibacterial, and anti-inflammatory effects and are used as a component in TCM for regulating blood fat and preventing cardiovascular and cerebrovascular diseases. Bamboo-leaf flavonoids are also used in cosmetics and as feed additive. In order to choose the best bamboo species for extraction of flavonoids and to set up a quality control method, the flavonoids in eleven samples of bamboo leaves of three genera collected from Yunnan, Fujian, Sichuan, Jiangsu and Jiangxi provinces are studied by HPTLC. HPTLC-AMD of sample extracts and the standards isoorientin, orientin, isovitexin, vitexin and tricin on silica gel, cleaned with methanol and methylene chloride and dried at 105 °C, with methanol – ethyl acetate – methylene – formic acid 4:7:9:2 to 50 mm in the first step, with acetone – methanol - ethyl acetate – methylene chloride – formic acid 1:2:7:10:2 to 75 mm in the second step, and with acetone - methanol - ethyl acetate - methylene chloride – formic acid 2:1:6:11:2 to 90 mm in the third step. Detection under UV 366 nm after spraying with 1 % aluminum trichloride in ethanol. Quantification of the flavonoids by densitometry at UV 366 nm via peak area. The quantitative method for different flavonoids was validated by investigation of the linearity (90-1750 ng/zone), the precision (%RSD=1.0-2.0 %, n=3 intra-day; %RSD=0.9-2.0 %, n=3 inter-day), and the repeatability (%RSD=0.9-1.9 %, n=9). The LODs were 25-40 ng/zone, and the recoveries were 81.3-106.9 % (n=3).

      J. Planar Chromatogr. 27, 333-339 (2014). TLC of alkaloids such as (1) papverine, (2) quinine, (3) berberine, (4) brucine, (5) emetine, (6) chelidonine, (7) boldine, (8) protopine and (9) allocryptopine on CN or RP18W phase with mixture of acetonitrile and water containing: acetic buffer at pH 3.6, 1 % acetic acid, 1 % ammonia, 0.01 M octane sulfonic acid sodium salt or methanol, and water containing 0.01 M diethylamine. On C18 plates, the best conditions for the separation of alkaloids were obtained with the mobile phase containing addition of octane sulfonic acid sodium salt, diethylamine, or aqueous ammonia; as for the CN plates, with aqueous eluents containing diethylamine or ammonia and nonaqueous eluent containing mixture of methanol, diidopropyl ether, and 2% ammonia. The efficiency of the system was increased by using a combination of two-dimensional thin-layer chromatography with multiple development chromatogram methods.
