Quinoline-Benzimidazole Conjugate Based Fluorescent Chemosensor: A Ratiometric Sensor for the Differentiation of Rutile and Anatase TiO2 Nanoparticles| Chapter 2 | New Innovations in Chemistry and Biochemistry Vol.7

 The quinoline-benzimidazole conjugate 1 was produced and analysed using standard spectroscopic and analytical techniques. As a possible fluorescent chemosensor, the probe is used to distinguish TiO2 anatase and rutile nanoparticles using the spectrofluorimetry technique. Probe 1 has a photoinduced electron transfer (PET) mechanism for selective TiO2 sensing and a ratiometric sensing response via an intramolecular charge transfer (ICT) mechanism for ratiometric sensing. Fluorescence titration data of TiO2 rutile and anatase phases with conjugate 1 were used to arrive at a 1:2 binding ratio, and the association constants (Ka) of 1+TiO2 anatase and 1+TiO2 rutile were calculated to be 6.34 104 M-2 and 5.179 104 M-2, respectively. Probe 1 had a detection limit of micro molar concentrations of TiO2 nanoparticles. Time and pH effects were also recorded. As a result, the probe 1 might be used on environmental and biological materials.

Determination of Phytochemical Extraction and Analysis of Medicinally Important Plant Cissus qudrangularis L. (Hadjod) | Chapter 8 | Highlights on Medicine and Medical Science Vol. 12

 The current study focuses on extracting and evaluating the many phytochemicals found in the plant Cissus qudrangularis. The indigenous medicinal plant of India, Cissus qudrangularis L. (Hadjod), belongs to the Vitaceae family. Bhava Prakash and Chakra Dutta prescribed it as a general tonic, especially for fractured patients, in ancient Ayurvedic writings. The stem of Cissus quadrangular L. is also used in Ayurveda as an alterative, anthelmintic, dyspeptic, digestive, tonic, and analgesic in the treatment of eye and ear ailments, irregular menstruation, asthma, and back and spinal issues. Plant extracts also have a cardiac tonic effect. Various tests revealed the presence of alkaloids, carbohydrates, and glycosides in the current study. Tannins are phenolic chemicals that are found in plants. Amino acids and protein Mucilage and gum Flavones and flavonoids are two types of flavonoids. Saponins Steroids and sterols can be found in a variety of extracts, including petroleum ether extract, chloroform extract, ethyl acetate extract, and n-butanol. In the Ethyl acetate fraction, preliminary qualitative chemical testing revealed positive findings for phytosterol, flavonoids, and triterpenoids. Carbohydrate, tannin, amino acid, and vitamin C were all positive in the hydro alcoholic fraction. The active ingredients in the stem of Cissus quadrangularis L. are flavonoids and triterpenoids, which may be responsible for its pharmacological actions. The study's findings may be beneficial in developing diagnostic indices for identifying the plant and preparing a monograph on it.

Determination of Physiochemical, Pharmacognostical, and Phytochemical Parameters of Premna herbacea | Chapter 9 | Technological Innovation in Pharmaceutical Research Vol. 6

 Herbal medicines have been used by practically all civilizations throughout history. Premna herbacea, a member of the Premna genus of the Verbenaceae family, was one of them. The goal of this chapter was to characterise the plant's morphological and microscopical characteristics. These plants' ethanol, chloroform, petroleum ether, and aqueous extracts were subjected to preliminary phytochemical investigation. Triterpenoids and alkaloids were found in abundance, along with trace levels of carbohydrates and flavonoids. The plant's physiochemical characteristics were within acceptable ranges. The fluorescence of root powder was detected under visible light and UV light of short and long wavelengths after it had been treated with various chemicals. They had a fluorescence to them. TLC and HPTLC analysis of several plant extracts also showed positive results. Premna herbacea has to be studied more in order to learn more about the hidden areas and their practical clinical applications that can benefit humanity.
