Formation and breakdown of citric acid in Garcinia fruit. (Xanthochymus guttiferae).
Two hypotheses have been put forward to explain the large accumulation of organic acids in fruits: (a) organic acids are not formed in the fruit, but are translocated from the leaves to the fruits which would act merely as storage organs (1, 2) ; and (b) the presence of the organic acids in fruits is due to the conversion of carbohydrates to organic acids in the fruit vesicles and not to transl...
متن کاملNoncytotoxic and Antitumour-Promoting Activities of Garcinia Acid Esters from Garcinia atroviridis Griff. ex T. Anders (Guttiferae)
The in vitro antitumour-promoting, cytotoxic, and antioxidant activities of two ester derivatives of garcinia acid, that is, 2-(butoxycarbonylmethyl)-3-butoxycarbonyl-2-hydroxy-3-propanolide (1) and 1',1''-dibutyl methyl hydroxycitrate (2), that had been previously isolated from the fruits of Garcinia atroviridis Griff. ex T. Anders (Guttiferae), were examined. Based on the inhibition of Epstei...
متن کاملComparative Vegetative Anatomical Study of the Genus Garcinia L. (clusiaceae / Guttiferae) in Sri Lanka
Vegetative anatomical studies of 10 species of Garcinia L., described by earlier workers to be present in Sri Lanka were carried out. A detailed anatomical investigation of lamina, petiole, young stem and wood, was carried out and the results were analyzed by statistical methods. The study agrees with previous workers in that there are 10 Garcinia species in Sri Lanka. Further, it also revealed...
متن کاملEffects of hormones applications on the germination of six populations of Garcinia kola Heckel (Guttiferae) seeds
The present study was carried out to investigate laboratory germination responses of six collections of Garcinia kola seeds to six different hormonal pre-germination treatments. This consisted of soaking seeds for three days in cool distilled water (control), in cool distilled water supplemented with 10 M of either naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D), benzylamin...
متن کاملThe purification of citrate-condensing enzyme.
The citrate-condensing enzyme was isolated as a crystalline protein from pig heart by Ochoa et al. (1). These workers reported that pig heart contained considerable quantities of the condensing enzyme. We were surprised when we obtained much higher yields of this enzyme from pig heart tissue with a different extraction procedure (2). This observation led to a purification procedure that yields ...
