- Abstract:
- ... The variations in isoflavonoid content in Radix Puerariae, the root of Pueraria lobata (Wild) Ohwi, have been examined in order to determine the optimum time to harvest the herb. Total isoflavonoid contents have been analysed by a UV spectrophotometric method whilst HPLC with photodiode array detection has been used to monitor the contents of seven major individual isoflavonoids, namely, 3-hydroxy ...

- Abstract:
- ... A new furostanol pentaoligoside and spirostanol tetraoligoside were isolated for the first time from yam tubers (Dioscorea pseudojaponica Yamamoto) from Taiwan, together with four known yam saponins, methyl protodioscin, methyl protogracillin, dioscin, and gracillin. Their structures were characterized as 26-O-β-D-glucopyranosyl-22α-methoxyl-(25R)-furost-5-en-3β,26-diol, 3-O-α-L-rhamnopyranosyl-(1 ...

- Abstract:
- ... The effects of domestic processing on steroidal saponins and furostanol and spirostanol glycosides in Taiwanese yam cultivar (Dioscorea pseudojaponica Yamamoto) were studied. The baking or frying of yam slices was conducted at 150, 180, and 200 °C for 3, 5, and 10 min. Yam slices were steamed or microwave cooked at 2450 MHz with an output power of 850 W for 3, 5, and 10 min. The various saponins w ...

- Abstract:
- ... The T locus of soybean (Glycine max (L.) Merr.) controls pubescence and seed coat color and is presumed to encode flavonoid 3'-hydroxylase (F3'H). The dominant T and the recessive t allele of the locus produce brown and gray pubescence, respectively. PCR primers were constructed based on the sequence of a soybean EST clone homologous to the F3'H gene. A putative full-length cDNA, sf3'h1 was isolat ...
