 หัวเรื่อง:วิธีการเพาะเลี้ยงคัพภะคู่ผสมข้ามชนิดของผักกะหล่ำ ผู้เขียน:ดร.ชวนพิศ อรุณรังสิกุล , Sumontha Nopparatana, Prateang Donsompai สื่อสิ่งพิมพ์:pdf AbstractVernalization of inbibed seed of Brassica campestris and B. juncea and one month old plant of B. oleracea were investigated at 5?C, contiouous illumination for 30 and 45 days, respectively. Vernalization procedures and flowering synchronization were adjusted to enhance the flower buds for making interspecies pollination. Then each pot plant was kept on growht cabinet which controlled 23-25?C and continuous light duration. Twenty days after pollination, the hybrid capsules were collected and embryos rescued into the modified MS medium additon with 10% (V/V) coconut juice, 300 mg/l casein hydrolysate, 0.1 gm/l NAA and 0.1 mg/l BA. Thirty days after culture the hybrid embryos between B. campestris x B. oleracea, B. juncea x B. campestris, B. juncea x B. oleracea, B. compestris x B. juncea were regenerated to plantles. Phenotype character of the interspecific hybrids and their parents were examined, the electrophoresis banding pattern of esterase (EST), malate dehydrogenase (MDH), and alcohol dehydrogenase (ADH) pattern were revealed, as well. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Hydroxychavicol and Eugenol Profiling of Betel Leaves from Piper betle L. Obtained by Liquid-Liquid Extraction and Supercritical Fluid Extraction) ผู้เขียน:Niramol Singtongratana, Sumontha Vadhanasin, Jirada Singkhonrat สื่อสิ่งพิมพ์:pdf AbstractThe chemical components of liquid-liquid extraction (LLE) and supercritical fl uid extraction (SFE) obtained from dried betel leaves (Piper betle L.) were determined and evaluated for the percentage extraction of hydroxychavicol (HC) and eugenol (EU). SFE was conducted at 60 ?C and a working pressure of 8 MPa (SFE1) and 6 MPa (SFE2. The chemical profiles were determined using high performance liquid chromatography (HPLC) with a method developed and validated for quantitative determination of HC and EU in the extracts from betel leaves. The analysis was carried out using HPLC on a Hypersil GOLD column (C18 with 250 ? 4.6 mm) using methanol-water (70:30 volume per volume) as the mobile phase under an isocratic system. The fl ow rate was 0.7 mL.min-1 and the detection was evaluated at the wavelength of 280 nm with a UV detector. The validation using hydroxychavicol (HC) and eugenol (EU) as a standard demonstrated a linear relationship (correlation coeffi cient = 0.997 and 0.998, respectively), with precision (relative standard deviation < 4%) in the concentration range of 40–100 ?g.mL-1 For HC and EU, the limit of detection was 1.0 and 0.1?g.mL-1, respectively, and the limit of quantifi cation was 2.0 and 0.2 ?g.mL-1, respectively. The highest extraction yield (15.6% weight per weight, w/w) and a high content of HC (9.1% w/w) were obtained by using ethyl acetate refl uxed extraction and LLE. A similar chemical profi le, regarding the HPLC fi ngerprint showed quality consistency by SFE1 with lower extraction yields. |
