Chayote is a plant which grow and develop throughout the year, contains of  93 mcg/100g folic acid. The aim of this research was to determine the ratio of sodium alginate with pectin and CaCl2 concentration coating to produce microcapsules of crude folic acid extract. Four phases of study was done, namely the manufacture of folic acid extract, manufacture of microcapsules with ionic gelation, analysis of folic acid content in the microcapsules, and the analysis of folic acid after storage of one week. Folic acid extract was made by maceration using alcohol 70% at pH 6, preparation of the microcapsules was using sodium alginate with pectin and folic acid was analysed using HPLC. Folic acid extract showed antioxidant activity of 98,1% with folic acid of 0,16 mg/kg. Microencapsulation of folic acid extract results showed the highest antioxidant activity was formed in alginate ratio of  70% to 30% pectin and CaCl2 concentration of 0.1 M i.e.  62.77 mg/kg. Folic acid is an antioxidant, highest antioxidant value folic acid was analyzed,  treatment was in alginate ratio of 70% to 30% pectin and CaCl2 concenration at 0.1 M i.e. 3.06 mg/kg, after one week at room temperature is became 2.39 mg/kg.

The "folic acid" content of cow's milk, as listed in the report of the Committee on Nutrition (Pediatrics, 31:329, 1963) is probably too low, as pointed out by Drs. Naiman and Oski. We would agree that these figures should be withdrawn until a more accurate assessment can be made. We are, however, less certain than they appear to be, that the L. casei assay, ascorbate-protected, will provide the information desired, i.e., the true total folate content of foodstuff biologically available to the human. For an understanding of the present situation, it is necessary to review briefly certain pertinent developments in this field.

Exposed to the pollution has led to generation of reactive oxygen species (ROS) in human skin. ROS generated cause many skin diseases such as skin-aging, inflammation, melanogenesis and skin cancer. ROS is a family of oxygen-based free radicals that contains or capable of producing an unpaired electron. Antioxidant is a molecule that can inhibit the reaction of free radical from ROS by donating its electron. Averrhoa bilimbi Linn. (AVBL) is one of the potent natural antioxidant belongs to the group of Oxalidaceae which can be widely found in Asia including Malaysia. Traditionally, this plant has been used to treat many diseases such as cough, itchiness, pimple, fever and inflammation. As a result, much attention has been directed towards the studies regarding the potential of this plant in treating disease. The present study was undertaken to assess the antioxidant activity of AVBL leaves extract. The AVBL leaves were extracted using sonicator with ethanol and distilled water as two different types of solvent. The total phenolic content (TPC) and flavonoid content (TFC) of this study were determined by using Folin-Ciocalteu reagent and aluminium chloride colometric assay. Antioxidant activity of the plant extract was tested using 2,2- diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing power (FRAP). From the analyses, water extract of AVBL possessed greater extraction yield (11.231%) as compared to ethanolic extract (5.358 %). However, ethanolic extract of AVBL leaves revealed higher result of TPC (126.4±0.35 mg/g gallic acid equivalent), TFC (32.80±0.37 mg/g quercetin equivalent), DPPH (0.0019±0.0003) and FRAP (41.81±0.45 mg/g gallic acid equivalent). The results of TPC and TFC have strongly positive correlation with antioxidant capacity (r = 1). Thus, it can be concluded that this plant is a potent source of natural antioxidant.

An increasing interest has been observed of beetroot leaf as a salad component due to recent studies focusing on their nutritional value. The randomized field experiment was carried out on lowland chernozem soil with 6 varieties, 3 replications and 2 sowing dates. Sampling was performed on 23 of August 2018 at the stage of 30 and 50 days of vegetation, where leaf (30 and 50 days) and root (50 days) were collected. Total dry matter, folic acid and nitrate content were evaluated. The results of this investigation show that higher total dry matter content was measured in the root (8.47–10.30%) compared to the leaf in both developmental stages (6.47–9.20%). Nevertheless, higher folic acid content was found in the young leaves of 30 and 50 days of development (58.77–113.86 µg 100g-1). Among the examined varieties, Bonel has presented great amount of folic acid not only in the leaves (99.35–113.61 µg 100g-1), but also in the root (89.99 µg 100g-1). Finally, lower nitrate content was found in Libero (316.16 mg kg-1) at 30 days and in Akela (340.41 mg kg-1) at 50 days of development. Thereby, fresh consumption of beetroot leaves are highly recommended.

Pramita DS, Handajani S, Rachmawanti D. 2008. The effect of heating technique to phytic acid content and antioxidant activity of velvet bean (Mucuna pruriens), butter bean (Phaseolus lunatus) and jack bean (Canavalia ensiformis). Biofarmasi 6: 36-44. Koro is a kind of local bean which has many varieties. The nutrition of koro is not different with soy, especially carbohydrate and protein which high enough, and has a low-fat content. However, koro also contains some harmful compounds, HCN which poisoned and phytic acid which an antinutritional compound. Besides as antinutritional compound, phytic acid has a positive role, i.e. as an antioxidant. Besides phytic acid, legume also contains the compounds of phenol and vitamin E that have antioxidant activity. The aims of this research were to determine the contents of phytic acid and antioxidant activity, and to determine the effect of heating technique on phytic acid and antioxidant activity of velvet bean, butter bean, and jack bean. The materials used were velvet bean, butter bean and jack bean obtained from Batuwarno, Wonogiri, Central Java. This research used a Completely Randomized Design (CRD) with five kinds of treatment, each treatment consisted of three replications. The treatments given were soaking by 3 days (P1), steaming (P2), boiling (P3) and pressure cooker (P4), which compared to a raw bean without heating treatment (P0). The investigated factors were phytic acid and antioxidant activity (DPPH Radical Scavenging Ability method). The results of this research showed the phytic acid content of velvet bean, butter bean and jack bean from the treatment of P0, P1, P2, P3 and P4 were degraded. The phytic acid of velvet bean of P0, P1, P2, P3 and P4 treatment were 10.87, 8.94, 4.56 and 1.72 and 1.46 mg/db, respectively; on butter bean were 11.78, 8.75, 4.77, 1.73 and 1.61 mg/db, respectively; while on jack bean were 9.04, 1.99, 1.39, 1.42 and 1.21 mg/db. The result of variance analysis showed the phytic acid content was significantly different (p<0.05). Antioxidant activity showed the increase from P0 to P1, then the degradation process at P2, P3, and P4. Antioxidant activity at velvet bean were 74.10%, 86.49%, 84.73%, 83.59% and 79.51%, respectively; at butter bean were 4.5%, 7.19%, 6.07%, 6.30% and 6.28%, respectively; at jack bean were 14.64%, 8.55%, 5.84%, 5.17% and 3.58%. The result of variance analysis showed antioxidant activity at velvet bean and jack bean was significant, while at butter bean for P1, P2, P3, and P4 were not significant. The conclusion that could be taken away from this research were heating techniques had an effect on the degradation of phytic acid at all kind of bean used, and also had an effect on the antioxidant activity at velvet bean and jack bean.
