Evolvulus alsinoides, commonly known as dwarf morning-glory and slender dwarf morning- glory, is flowering plant from the family Convolvulaceae. Traditionally this plant is used as blood purifier, brain tonic, an antimicrobial agent and for memory loss. This work is done for determining whether the cream prepared by the aqueous extract of Evolvulus alsinoides has antimicrobial activity. The dried plant leaves are extracted using water as the solvent. The extractive value is calculated and was found to be 12.5%w⁄w. The phytochemical screening of the extract was performed and it contains slight amount of glycosides, carbohydrates, proteins, alkaloids and tannins. Then using that aqueous extract, a cream was formulated and its evaluation was carried out. From the evaluation the cream was found to be light brown in color with a characteristic odour and have smooth texture. pH and viscosity of the cream are 5.58 and 13254mpas respectively. Cream was homogeneous by its visual appearance with a smooth and good consistency. On application, the cream was non-slippery, smooth and easily removable, also does not show any irritation on skin. After that the antimicrobial activity of the cream was tested using agar well diffusion method. Gentamicin was used as the standard reference drug. The antimicrobial sensitivity was determined using zone of inhibition. In our study, the cream containing aqueous extract displayed antimicrobial activity against Staphylococcus aureus and Escherichia coli. The cream was found to be more active against gram-negative (Escherichia coli) bacteria. The identified phytochemical compounds viz., glycosides, tannins and alkaloids may be responsible for the antimicrobial activity of Evolvulus alsinoides.
Poultry farming is one of the most developed industries, and it is very important to operate the industry completely without waste. More than 20,000 chickens are slaughtered in poultry factories per month. Taking into account that on average 100 grams of feathers are extracted from one chicken, the main goal is to extract keratin protein by processing more than 2 tons of chicken feathers per month. During the research, my method of extracting protein from feathers will be discussed. In addition, determination of the amount of nitrogen in the protein isolated by a special method, determination of the total protein and amino acids are discussed. In the results section, it was found that 25% dry mass was extracted, it contained 17 different amino acids. It was concluded that chicken feather protein can be used for cosmetics based on theoretical comparisons with keratin protein. Hair is composed mainly of keratin protein and a small amount of lipid.
Carthamus tinctorius l gullari an'anaviy ravishda yurak-qon tomir, serebrovaskulyar va ginekologik asoratlar uchun qo'llaniladi. Shu bilan birgalikda yurak-qon tomir kasalliklari uchun Carthamus tinctorius l suvli ekstraktining fitoterapevtik hamda, antikoagulyant, qon tomirlarini kengaytiruvchi, antihipertenziv, antioksidant, neyroprotektiv, immunosupressiv, melanin sinteziga inhibitiv ta'sir ko'rsatadigan saratonga qarshi vosita sifatida dunyo olimlari ilimiy tadqiqotlar olib borishmoqda. Bundan tashqari, Carthamus tinctorius l neyrotrop, kardiotrop, gemopoetik va diaforetik tizimlar bilan bog'liq boshqa kasalliklar uchun ham samarali ekanligi aniqlangan. Ushbu o'simlikning fitokimyosiga kelsak, tegishli tadqiqotlar o'simlikning turli qismlaridan aniqlangan flavonoidlar, feniletanoid glikozidlar, kumarinlar, yog' kislotalari va steroidlar kabi bir qator faol tarkibiy qismlarni aniqladi. Hozirgi vaqtda bir qator farmatsevtika tadqiqotlari uning antioksidlanish, yallig'lanishga qarshi va antiepilepsiya nuqtai nazaridan etnofarmatsevtik qo'llanilishiga e’tibor qaratilgan. Biz olib borgan tadqiqot Carthamus tinctorius l ning antioksidantlik xususiyatlarini ko‘rib chiqish.
Mazkur maqolada badiiy asar strukturasida sarlavhaning ahamiyati xususida mulohaza yuritiladi. Asar sarlavhasida muallif g‘oyaviy,estetik qarashlarining namoyon bo‘lishi yoritiladi. Ma’no nuqtalarining yaxlitlik kasb etishi mohiyatni aniq ravshan anglatish imkonini berib, asar estetik quvvatini oshiradi. Sarlavhada tabiatdagi unsurlar nomi vositasida ramziylik, ishoraviylik ortib boradi. Badiiy muloqotga kirishayotgan san’atkor kitobxonga ma’lum axborot, yangilikni yetkazibgina qolmay, uni ijodiy yondashuvga chorlashi darkor.
Tarkibdagi ilk semiotik markaz sarlavha bo‘lib, unda muallif g‘oyasi, konsepsiyasi jo bo‘ladi. Sarlavha ilk taassurot, muallif hamda kitobxonning ruhiy muloqoti debochasi. San’atkorlar borlig‘i, iste’dodi, ijodiy niyatini baholash shu lahzadan boshlanadi. “Yur, tog‘larga ketamiz”, “Qoyalar ham yig‘laydi”, “Saodat sohili” kabi qissalar maskan nomi bilan quvvatlanadi. Makon tasviri estetik zavq beribgina qolmay, shu maskan bilan bog‘liq asosiy voqea, kalitga ishora beradi.
Ilk jumla muloqotning ibtidosi, qahramon hamda kitobxonning g‘aybona uchrashuvi, kompozitsion sathning muhim belgisi. Keyingi holatu vaziyat, dialogu monolog debochasi. Mavzu, muammolar borasidagi ilk taassurot, bu keyingi bosqichga ko‘tarilish, faollikni jadallashtirish jarayoni. Qissada epigraf poetik mazmunni umumlashtirish, badiiy niyatni uqishda muhim sanaladi. Muallif yoritayotgan masalaga doir zarur ko‘chirma (she’r, hikmat, maqol, hadis kabi)ni kiritib, g‘oyaviy, hissiy salmoqdorlikni oshiradi. U asosiy ma’noni o‘zida jo aylagani, qahramon holatini asoslashi, fikrni tasdiqlashi bilan e’tiborni tortadi.
