Cotton cultivars with brown (Xiangcaimian 2), green (Wanmian 39) and white (Sumian 9) fiber were investigated to study fiber developmental characteristics of natural-colored cotton and the effect of hormones on fiber quality at different stages after anthesis. Fiber lengths of both natural-colored cottons were lower than the white-fibered control, with brown-fibered cotton longer than green. Fiber...
Biodiesel production from soybean oil transesterification under the presence of a heterogeneous catalyst tri-potassium phosphate in subcritical methanol has been studied. The results showed that tri-potassium phosphate exhibited high catalytic activity for the transesterification of soybean oil. The effects of reaction variables, including the reaction temperature, the molar ratio of methanol to oil,...
The methanol extract of aerial parts of Salvia splendens afforded three new diterpenes: 15,16-epoxy-1β-hydroxy-trans-cleroda-2,13(16),14-trieno-12,17; 19,18-diolide: 15,16-epoxy-11β-acetoxy-trans-cleroda-2,13(16),14-trieno-12,17: 19,18-diolide and 1β,11β-diacetoxy-15-hydroxy-trans-cleroda-2,13-dieno-12,17; 15,16; 19,18-triolide named splenolide A, B and C. Their structures were established on the...
