| plants with a reputation against snakebite. | many plants are recommended in traditional medicine as active against various effects of snakebite. few attempts have been made to investigate the veracity of these assertions in controlled experiments. several workers, mainly oriental, have investigated the reputation of such plants by performing in vitro and in vivo experiments in order to demonstrate whether there was any protective effect, using drugs or mixtures of drugs prepared using traditional formulae. in some studies, these extracts w ... | 1992 | 1440620 |
| novel pathways of oleic and cis-vaccenic acid biosynthesis by an enzymatic double-bond shifting reaction in higher plants. | the novel pathways of oleic acid formation from cis-vaccenic (cis-11-octadecenoic) acid and of cis-vaccenic acid formation from oleic acid by enzymatic positional isomerization have been proposed in higher plants, based on stable-isotope experiments using [2,2-2h2]cis-vaccenate or [2,2-2h2]oleate as an immediate precursor. a pulp homogenate and also pulp slices prepared from developing kaki (diospyros kaki) fruit could catalyze these hitherto unknown isomerizations. this suggests the presence of ... | 1990 | 2358068 |
