In the present study, the nutritional compositions of maca which was grown in a mountain area at an elevation of 2 200-2 800 m of Ebian County,Sichuan Province were measured, and then HPLC analysis on two representative active compounds（macaene and macamide） in the maca sample was *** results revealed that there were 24.20% total protein, 18.40% total amino acids（including 3.84% arginine）, 42.80% total sugars, 1.36% fat and kinds of minerals（including 1.14% potassium） in Ebian maca. HPLC fingerprints of macaene and macamide of Ebian maca were similar to those of Peru maca. The results suggested that maca could be cultivated with good quality in some mountain areas with an altitude1 000 m lower than the origin place in Peru.

Portulaca oleracea L.,commonly known as purslane,is a worldwide weed species belonging to the family Portulacaceae and has been known as“Global Panacea”.As one of the most widely consumed green vegetables and medicinal plants around the world,it has recently been re-evaluated as a potential“new crop”due to the properties that differentiate it as one of the best vegetable sources of omega-3 fatty acid(α-linolenic acid),as well as a variety of nutrients and ***,emerging research has found that purslane exhibits health-promoting properties like anti-inflammatory,anti-hyperglycemic,antioxidant,neuroprotective,and *** findings suggest that this species possesses a potential using as a dietary supplement beyond potherb and traditional *** review systematically summarizes the up-to-date research carried out on purslane,including the nutritional compositions,bioactive compounds,and health benefits it exerts as well as limitations,challenges,and future directions of ***,we hope that this review would provide purslane with a comprehensive reference and future scope as functional and health-promoting food for disease prevention and treatment.

Light shading improves the yield and quality of seed in oil-seed peony(Paeonia ostii Feng Dan)

Journal of Integrative Agriculture 2018年第7期17卷 1631-1640页

Tree peony seed is unique for its super-high content of unsaturated fatty acid and is thus considered as an important source of woody oil. However, photosynthetic production is greatly reduced under high light intensity and air temperature during the seed filling period, which negatively affects seed yield and quality. The objective of this study was to determine if appropriate shading improves yield and quality of seed in oilseed peony. In this study, oilseed peony trees were shaded by different density polyethylene nets from four weeks after flowering to harvest stages to form light, moderate, and severe shadings, equivalent to about 80, 40, and 20% of full solar exposure, respectively. The effects of different shadings on some physiological parameters, yield and yield components, and nutritional composition of seed were examined. Averaged across two years, light shading increased the actual net photosynthetic rate（P_n） by 16.8%, the maximum net photosynthetic rate（P_（max）） by 81.4%, chlorophyll（Chl） content by 52.8%, auxin（IAA） content by 38.1%, and gibberellic acid（GA_3） content in leaves by 6.3%; it decreased the accumulation of H_2O_2 in leaves by 24.8%, malondialdehyde（MDA） by 22%, and endogenous abscisic acid（ABA） by 8.8%, indicating that leaf senescence in late season was considerably delayed. Light shading increased seed yield, and contents of crude fat and unsaturated fatty acids by 9.7, 5.6, and 9.6%, respectively, while moderate or severe shading significantly reduced all the three parameters. Light shading increased seed weight, but moderate or severe shading reduced seed weight or follicle density. The improved seed yield under light shading was mainly due to increased seed weight, while the reduced seed yield under moderate or severe shading was mainly attributed to reduce follicle density and seed weight. The improved seed weight and content of unsaturated fatty acids under light shading was possibly due to the delayed leaf senescence. The overall r
