Curcuma longa is an important dietary plant which possess several pharmacological activities, including antioxidant, antimicrobial, anti-inflamatory, anticancer and anti clotting etc. The aim of the present study was to determine the phenolic profile of Curcuma longa and in vitro antioxidant and antidiabetic activities. In HPLC chromatogram of Curcuma longa rhizome extract 15 phenolic compounds were identified namely Digalloyl-hexoside, Caffeic acid hexoside, Curdione, Coumaric, Caffeic acid, Sinapic acid, Qurecetin-3-D-galactoside, Casuarinin, Bisdemethoxycurcumin, Curcuminol, Demethoxycurcumin, and Isorhamnetin, Valoneic acid bilactone, Curcumin, Curcumin-O-glucuronide respectively. The ethanolic extract displayed an IC50 value of 37.1±0.3 µg/ml against alpha glucosidase. The IC50 value of DPPH radical scavenging activity was 27.2 ± 1.1 μg/mL. It is concluded that ethanolic extract of Curcuma long is rich source of curcumin and contain several important phenolics. The in vitro antioxidant and alpha glucosidase inhibitory effect of the plant justifies its popular use in traditional medicine.

Abstract. Putranto HD, Setianto J, Santoso U, Warnoto, Nurmeliasari, Zueni A. 2012. Estradiol-17β hormone concentration and follicles number in exotic Burgo chicken supplemented by Sauropus androgynus leaves extract. Biodiversitas 13: 1-6. Bengkulu Province of Indonesia has an indigenous crossbreed chicken named burgo or Rejang chicken. A conservation effort in this study was represented by supplementing 4 different levels of Sauropus androgynus or katuk leaves extract (KLE) to improve number of fertile eggs. The purpose of study was to identify the effects of KLE supplementation on female burgo chicken's serum estradiol-17β (E2) hormone concentration profile and number of follicles. KLE was added into drinking water (0, 9, 18 and 27 g/chicken/day) during 8 weeks of treatment. The results showed that supplementation of KLE dosed 9 to 27 g/chickens/day had significantly affected E2 concentrations and number of follicles (P < 0.05). In contrast, the average of female burgo E2 concentration with supplemented KLE was higher than control group. The total number of small follicle yield was highest (86.5%) compared to medium follicle (7.8%) and large follicle (5.3%). Many primary follicles (primordial) and post ovulatory follicles were probably in micro size and unseen by an usual visual counting. It seems that serum E2 hormone concentration correlated to total number of preheararchal follicles. Supplemented KLE was able to improve the serum estrogen steroid hormone concentration and number of preheararchal follicle (small and medium follicles) in female burgo chicken.

Background: In the present era, the attention of nutritionist diverted towards the bioactive entities present in natural sources owing to the presence of health boosting perspectives against lifestyle related disarrays. Methods: In this context, different parts of ginger crop i.e. rhizome, leaves and flower of variety Suravi (ID no. 008) were used for the preparation of ginger extracts with 50% methanol, 50% ethanol and water via rotatory shaker for 45 min. After that, different phytochemical analysis and in vitro analyses were carried out to determine the antioxidant potential of these extracts. Lastly, the best selected extracts from each part was quantified through HPLC. Results: The results of current investigated indicated that ethanol extract proved to have maximum quantity of phytoceutics as compared to methanol and water. The maximum TPC, flavonoids, flavonols, DPPH assay, antioxidant activity, FRAP assay, ABTS assay and metal chelating potential was observed in ginger leaves as 780.56 ± 32.78 GAE/100 g, 253.56 ± 10.65 mg/100 g, 49.54 ± 1.74 mg/100 g, 75.54 ± 3.17%, 77.88 ± 3.27%, 105.72 ± 4.44 μmole TE/g, 118.43 ± 4.97 μmole TE/g and 35.16 ± 1.48%, respectively followed by ginger flowers and ginger rhizome. The lowest antioxidant activity was estimated in ginger rhizome. On the basis of phytochemical profiling and in vitro analyses, ethanol extracts of ginger flowers, leaves and rhizome were selected for the quantification through HPLC. Conclusion: The findings proved that maximum 6-gingerol was present in ginger leaves (4.9 mg/g) tackled by ginger flowers (2.87 mg/g) and ginger rhizome (1.03 mg/g).

The present study was conducted to investigate the impact of various treatments of xylanase produced by Aspergillus niger applied in bread making processes like during tempering of wheat kernels and dough mixing on the dough quality characteristics i.e. dryness, stiffness, elasticity, extensibility, coherency and bread quality parameters i.e. volume, specific volume, density, moisture retention and sensory attributes. Different doses (200, 400, 600, 800 and 1,000 IU) of purified enzyme were applied to 1 kg of wheat grains during tempering and 1 kg of flour (straight grade flour) during mixing of dough in parallel. The samples of wheat kernels were agitated at different intervals for uniformity in tempering. After milling and dough making of both types of flour (having enzyme treatment during tempering and flour mixing) showed improved dough characteristics but the improvement was more prominent in the samples receiving enzyme treatment during tempering. Moreover, xylanase decreased dryness and stiffness of the dough whereas, resulted in increased elasticity, extensibility and coherency and increase in volume & decrease in bread density. Xylanase treatments also resulted in higher moisture retention and improvement of sensory attributes of bread. From the results, it is concluded that dough characteristics and bread quality improved significantly in response to enzyme treatments during tempering as compared to application during mixing.

Latar belakang: Stunting merupakan retardasi pertumbuhan linier kurang dari standar menurut usianya. Masalah stunting masih merupakan salah satu masalah terbesar di Kabupaten Gorontalo. Tujuan penelitian: Diketahuinya pengaruh faktor ibu, pola asuh, dan variasi MPASI terhadap kejadian stunting di Kabupaten Gorontalo. Metode: Desain penelitian menggunakan Case Control Study. Seluruh balita di Kabupaten Gorontalo menjadi Populasi studi. Sampel kasus merupakan balita yang menderita stunting, dan sampel kontrol adalah balita normal. Jumlah sampel sebanyak 118 balita. Sampel kasus dipilih dengan menggunakan purposive sampling dan sampel kontrol dipilih menggunakan random sampling. Data dianalisis dengan menggunakan uji Chi Square dan Logistic Regression. Hasil: pola asuh (OR = 3,901, 95% CI 1,692 – 8,994), variasi MPASI (OR = 3,260, 95% CI 1,371 – 7,750), riwayat KEK (OR = 2,482, 95% CI 1,013 – 6,081) dan pendidikan ibu (OR = 2,345, 95% CI 1,007 – 5,456). Umur ibu, pemberianASI Ekslusif, makanan pendamping ASI (MPASI), konsumsi snak hampir tiap hari, dan konsumsi mie instan > 3 kali dalam seminggu bukan merupakan faktor risiko kejadian stunting. Simpulan: Faktor ibu yaitu pendidikan ibu, riwayat KEK, pola pemberian MPASI, dan pola asuh merupakan faktor risiko kejadian stunting.

Survivability of probiotics is severely affected by harsh gastrointestinal conditions. In the present study, microbeads of Lactobacillus rhamnosus GG were formulated using alginate (1.5% w/v) and combination of alginate (1.5% w/v) with xanthan gum (0.5% w/v) through an emulsion technique to improve bacterial viability in low pH orange juice and in gastrointestinal conditions. The microbeads were tested for encapsulation efficiency, survivability in bile salt, SGF (simulated gastric juice), SIF (simulated intestinal fluid), and storage stability. Probiotic orange juice was formulated and tested for physicochemical parameters (pH, titratable acidity, and total sugars) and sensorial properties during storage. Gum-coated alginate microbeads (T3) showed higher encapsulation efficiency, i.e., 95.2% compared to alginate microbeads (T2), i.e., 86.85%. Similarly, T3 showed the highest resistance against bile salt (8.50 log CFU/g), SGF (7.95 log CFU/g), and SIF (8.0 log CFU/g) during 80 min exposure compared to T2 and free cells. The viability of gum-coated alginate beads (T3) remained above 107 CFU/g in gastrointestinal conditions and at the end of 21 days storage (8.3 log CFU/mL). All physicochemical parameters of probiotic juice were significantly ( p ≤ 0.05 ) decreased with respect to storage except acidity. In addition, minimal changes in physicochemical parameters were observed in T3 compared to other treatments. Treatment had no significant impact on the sensory characteristics of juice, but storage had a significant effect ( p ≤ 0.05 ) on the sensory characteristics of juice. The alginate gum microbeads improve the survivability of probiotics for targeted delivery. Hence, encapsulated probiotics can be used for functional beverage development to take advantage of their therapeutic benefits.
