      (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).

      M. FAIYAZUDDIN*, J. ALI, S. AHMAD, N. AHMAD, J. AKHTAR, S. BABOOTA (*Formulation Research Laboratory, Department of Pharmaceutics, Faculty of Pharmacy, Jamia Hamdard, New Delhi-110062, India, and Department of Pharmaceutics, Faculty of Pharmacy, Integral University, Lucknow-226026, Uttar Pradesh, India; md.faiyazuddin2008@g.mail.com)

      J. Planar Chromatogr. 23, 233-236 (2010). HPTLC of trans-citral and cis-citral in lemongrass oil on silica gel with toluene - ethyl acetate 17:3 in a twin-trough chamber saturated for 15 min (at 25 °C and 55 % RH). Detection by spraying with vanillin-sulfuric acid reagent. Quantitative determination by absorbance measurement at 595 nm. Intra-day and inter-day precision were evaluated by replicate (n = 6) analysis of samples (trans-citral at 450, 900, and 1800 ng/band, and cis-citral at 470, 940, and 1880 ng/band). The linear range was 225-3600 ng/band for trans-citral, and 470-3760 ng/band for cis-citral. The correlation coefficient r was 0.9933 for trans-citral and 0.9937 for cis-citral. Intra-day precision (n = 6) was < 3.56 and 5.66 % for trans- and cis-citral, respectively. Inter-day precision was assessed to be < 3.47 and 5.52 % for trans- and cis-citral by repeating the intra-day assay on three different days. Repeatability of sample application and peak-area measurement was 0.98 %, determined by performing six replicate analyses of the same band (1800 ng/band trans-citral and 1880 ng/band cis-citral). The RSD of recovery of trans and cis-citral was in the ranges 1.36-3.25 and 1.64-3.47, respectively.
