“…Recently, there has been a surge of interest in using enzyme inhibitors as a biochemical control. Various specific and non-specific inhibitors have been employed and their effectiveness has been investigated in various fruits (Choi et al 2005;Sun et al 2011;Wang et al 2011). The membrane integrity of litchi cultivar feizixiao broken down most seriously than other cultivars because of its increased PLD activity (Sun et al 2012).…”

Combinatorial approaches for controlling pericarp browning in Litchi (Litchi chinensis) fruit

The availability of fruit like litchi has been limited by variability in yield, alternate bearing, seasonal differences and most commonly post harvest problems. The litchi fruit has a very short shelf-life during which red color turns brown which greatly affects the appeal to consumer although not the unique flavor. This review article focuses on the post harvest problems especially browning of litchi. The pericarp of litchi is also sensitive to desiccation and turns brown and brittle once moisture is reduced to half. A large number of approaches have been tried to solve this problem starting from hydro-cooling to gamma irradiation but single approach could not suffice for all. In modern era, the logical base of controlling browning is either to control the responsible enzyme or remove the undesirable product of enzyme catalyzed reaction. Thus enzyme technology with good postharvest practice can definitely solve this problem.

“…Phenolic compounds are the most widely distributed type of plant secondary metabolites (Singh et al 1998). These compounds have many significant bioactivities, such as scavenging free radicals, chelating metals, regulating enzyme activity, and modulating cell proliferation (Wang et al 2011).…”

Plant tissue culture can readily be applied to the field of medicinal plants and secondary metabolites production. In this study, in vitro propagation protocol of Rumex cyprius Murb. was established. The highest shoot multiplication rate was observed from explants grown on MS medium supplemented with 1.5 mg/L BA (7.8 shoots per explant). For rooting, the maximum root induction rate was observed on MS medium supplemented with 1.5 mg/L IBA or 1.0 mg/L NAA. The longest roots were observed for plants grown on MS medium supplemented with 1.5 mg/L IBA. For callus induction, leaves from in vitro grown plants were cultured in various levels of 2,4-D or different combinations of BA and NAA. The highest fresh weight (5.86 g) of calli was observed at 1.5 and 0.5 mg/L BA and NAA, respectively. The second part of this work investigated the effects of abiotic factors (NaCl and Mannitol) and biotic factors (Yeast extract and Chitosan) on secondary metabolites accumulation of in vitro grown R. cyprius. Phenolic compounds were extracted, and the individual phenolic compounds and antioxidant activity of the extracts were determined of in vitro grown R. cyprius. The total phenol content and antioxidant activity increased significantly by the pervious factors. Reversed high-pressure liquid chromatography (RP-HPLC) was used to measure the effect of these factors on the contents of individual phenolic compound. New phenolic compounds (Gallic acid and Chlorogenic acid) not found in R. cyprius plants grown on control media were produced in R. cyprius plants grown on media supplemented with elicitors. Results indicate that using elicitors in plant tissue culture could be used to produce/enhance secondary metabolites accumulation in R. cyprius.

“…Health advantages of phenolic compounds such as antithrombotic, anticarcinogenic and vasodilatory activities have been demonstrated (Cook and Samman 1996;Wang et al 2011). Vitamins, phenolic substances and carotenoids are the three major groups of natural antioxidants involved in defenses against several diseases (Thaipong et al 2006).…”

Primula heterochroma is indigenous to Caspian coast forests in the north of Iran. Total phenols, total flavnoids, total carotenoids and antioxidant capacity of 50 P. heterochroma accessions were investigated. The highest total phenol (1272.31 mg GA equivalent/100 g fresh weight) and total flavonoids (615 mg catechin/100 g fresh weight) were observed in G5 accession from Saravan. The highest antioxidant activity was observed in G14 accession (73.03 %) from Kacha, followed by G2 accession (69.75 %) and G5 accession (66.84 %) from Saravan. The results of HPLC analysis showed that quercetin-3-glucoside was the major phenolic compound widely found in these accessions followed by chlorogenic acid. There was a linear relationship between the antioxidant capacities and the total phenols and total flavonoid. Inversely, there was no statistically significant correlation between total carotenoid and antioxidant activity. Based on the path coefficient analysis, the maximum direct effect on antioxidant was observed in total phenols (0.908). In addition, the cluster analysis based on Euclidean distance with Unweighted pair-group method using arithmetic average (UPGMA) method separated the accessions into four main groups. Our results supported that Iranian wild primrose accessions possess valuable antioxidant properties for therapeutic and potential medicinal use.
