Abstract

Solanum torvum has potential as a functional food ingredient because it contains bioactive antioxidant compounds which are quite high and are proven as herbal medicines in China and are a popular food in Florida, Alabama, West India, Malaysia, Thailand, Mexico, Central America, South America, Brazil. The study aims to analyze the components of bioactive antioxidant compounds and nutrients in qualitative and quantitative methods and functional groups in fresh Solanum torvum. The research method used phytochemical screening, quantitative tests, chemical identification with LCMS, FTIR, AAS. The results of phytochemical screening studies, the Solanum torvum contains few alkaloids, while it contains a great number of saponins, steroids, glycosides. The quantitative test showed that the fruit contains 36.31 mg /g phenol, 0.62 mg/g tannin content, 2.76 mg/g flavonoid content and antioxidant activity (% DPPH inhibition) of 84.55%, 82.77% water content, 1.63% ash content, 2.73% fat content,  9.78% protein, 3.69% carbohydrates, 3.77% vitamin C, 0.97% phosphorus, 0.13% potassium, Ca 36.64 ppm, Mg 79.1 ppm, Fe 2.34 ppm. Chemical tests with LCMS contain 13 types of components namely (1) chlorogenic acid, (2) 4-O-caffeoylquinic, (3) 3-O-caffeoylquinic, (4) 4-O-caffeoylquinic, (5) 3-O-feruloylquinic acid, (6) 5-O-feruloylquinic acid, (7) 3-O-dicaffeoylquinic acid, (8) 4-O-dicaffeoylquinic acid, (9) 3-5-O-dicaffeoylquinic acid, (10) 3-O -feruloylquinic acid, (11) 5-O-feruloquinic acid, (12) putative dicaffeoylquiniacid, (13) putativedicaffeoylquinic acid. The functional groups of Solanum torvum have seven types namely phenol (OH), Alkane (C-H), Alkene (C = C), aromatic ring, Nitro (NO2), Amine and Amide (C-N), Alcohol (C-O). Thus, fresh Solanum torvum contains potential antioxidant compounds and nutrients that function for health and functional food.

Abstract

Pokak (Solanum torvum) can thrive in Indonesia and had high phytochemical and antioxidant compounds. The aim of this study was to analyze the effect of antioxidant compounds on herbal tea products, namely methanol extract of pokak herbal tea and water extract of pokak herbal tea on the inhibition of the growth of pathogenic bacteria. The herbal tea processing method uses surface response. The measured parameters were the total phenol content, tannins, flavonoids, and antioxidant activity (% DPPH Imbibition) and test for pathogenic bacteria inhibition zone using the disc method. The results showed that the best treatment was pokak green tea water extract containing 93.81% antioxidant activity (% DPPH inhibition), total phenol 55.20 mgGAE/g, tannin content 1.70 mgTAE/g, flavonoid levels 1.78 mgQAE/g. Analysis of pokak green tea water extract at a concentration of 100% had an inhibitory power against pathogenic bacteria E coli 20 mm, 20 mm MRSA, 20 ml Salmonella typhi, 19 mm Streptococcus pneumonia. Pokak green tea water extract can be used as a drink that functions for health in inhibiting the growth of pathogenic bacteria.

Abstract

The research aimed to study the interaction between the effects of various types of mulch and fertilizers on the growth and production of long beans. The research used a randomized block design, Factor I type of mulch consisting of 3 levels: M0 = No mulch, M1 = black and silver plastic mulch, and M2 = Straw mulch. Factor II is the type of fertilizer: including P1 = NPK Mutiara 600 kg/ha, P2 = biological Petrobio 90 kg/ha, P3 = NPK Mutiara 50% + biological Petrobio 50%. The results showed the effects of various types of mulch and fertilizers have significant interaction between the growth of leaf number and fruit weight of long beans, namely M1P3 (black silver mulch and application of 50% pearl fertilizer and 50% biological Petrobio).
