未尽利用热带水果,即在当地消费和医用的非贸易热带水果,未普及化,生长于野外,季节性强,但富含多酚类化合物、类胡萝卜素、花青素、脂肪酸、矿物质和氨基酸,因而具有一定的开发潜力。在马来西亚,热带水果丰富多样,主要有普通水果、观赏水果、特有水果、野生水果和高地水果,但大部分水果都未能充分利用,其中,典型的有罗望子、巴杖果、砂拉越芒果、钮扣山竹、榴莲、莲雾、挂尼芒果、野红毛丹和蛇皮果。这些水果可以分为3个类型：具有贸易开发潜力的主要包括无花果（Ficus sp.）、罗望子（Garcinia atroviridis）、尖必达（Artocarpus integer）、鲜花木果（Lepisan-thes alata）、野榴莲（Durio sp.）、橄榄木（Spondias cytherea）、菠萝蜜（Artocarpus heterophullus）、槟榔（Areca catechu）、野红毛丹（Nephelium ramboutan-ake）、蛇皮果（Salacca zalacca）和面包果（Artocarpus altilis）;具有适于当地人们利用潜力的水果种类包括木胡瓜（Averrhoe bilimbi）、榔拜果（Baccaurea motteyana）、单贝果Baccaurea macrocarpa）、喃喃果属（Cynometra cauliflora）、西柚（Dialum indum）、黄肉榴莲（Durio kutejensis）、野生山竹（Garcinia hombroiniana）、野檬果（Garcinia parvifolia）、巴杖果（Mangifera feotida）、醋栗（Phyllanthus emblica）、蒲桃（Syzygium jambos）;不具有经济利用开发潜力的水果种类包括哥露比（Salacca conferta）、青枣（Zizyphus mauritiana）、木奶果属（Baccaurea polyneura）、野檬果（Garcinia parvifolia）、番龙眼（Pometia sp.）、赤才果（Leppisanthes rubiginosa）、波漆果（Bouea microphylla）、蛋黄果（Pouteria campechiana）和仙都果（Sandoricum koetjape）。目前,有关未尽利用水果研究仍处于初期阶段,有必要使这些水果更为普及并得到有效利用,因此,政府和私人组织须采取一些措施以促进这些水果的消费。今后需对这些水果的营养成分、抗氧化作用以及疗效进行深入研究。  相似文献   

Improving the lipid profile in hypercholesterolemia-induced rabbit by supplementation of germinated brown rice

It is imperative that there be a diet designed specifically to improve lipid profile in order to impede the progress of atherosclerosis. Because rice is a staple food in Asia, it will be chosen as the diet of interest. This study sets out to discover whether consumption of different processed rice diets may result in a change of the lipid profile. The experiment was done on male New Zealand white rabbits after 10 weeks of treatment with diet containing 0.5% cholesterol. The experimental diets include white rice (WR), brown rice (BR), and germinated brown rice (GBR). Among them, rabbits fed a GBR diet demonstrated significantly lower levels of total cholesterol (TC), low-density lipoprotein (LDL), LDL/HDL, and atherogenic index (AI) and a higher level of high-density lipoprotein (HDL). Results from atherosclerotic plaque assessment further support the findings. The level of malondialdehyde (MDA), which acts as an indicator for oxidative stress, was also reduced by GBR diet. The positive change in lipid profile in the rabbits fed GBR appeared to correspond with the higher amounts of γ-oryzanol, tocopherol, and monounsaturated fatty acid (MUFA) content.  相似文献   

Identification and quantification of phenolic compounds in bambangan (Mangifera pajang Kort.) peels and their free radical scavenging activity     

Hassan FA  Ismail A  Abdulhamid A  Azlan A 《Journal of agricultural and food chemistry》2011,59(17):9102-9111

Phenolic compounds and antioxidant capacity of acidified methanolic extract prepared from fully ripe bambangan (Mangifera pajang K.) peel cultivated in Sarawak, Malaysia, were analyzed. The total phenolic content (98.3 mg GAE/g) of bambangan peel powder (BPP) was determined by the Folin-Ciocalteu method. BPP showed a strong potency of antioxidant activity and was consistent with that of BHT and vitamin C as confirmed by the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and FRAP (ferric-reducing antioxidant power) assays. Gallic acid, p-coumaric acid, ellagic acid, protocatechuic acid, and mangiferin were the major compounds among the 16 phenolics that have been identified and quantified in M. pajang peels with 20.9, 12.7, 7.3, 5.4, and 4.8 mg/g BPP, respectively. Peak identities were confirmed by comparing their retention times, UV-vis absorption spectra, and mass spectra with authentic standards. The 16 phenolic compounds identified in M. pajang K. using HPLC-DAD and TSQ-ESI-MS are reported here for the first time.  相似文献
