The well-known tropical tree Psidium guajava, also known as the guava, is widely farmed for its fruit. This article consists of literature about various analytical techniques like TLC, UV spectrophotometry, HPLC, and HPTLC that could be used to analyze the Guava plant. The HPLC analysis of Quercetin isolated from the leaves of the guava plant uses a 4 x 125 mm Hypersil ODS column with a mobile phase of 0.5 percent ortho-phosphoric acid in water and methanol at a flow rate of 1 ml/min. The column wash times are 20 min and 18 min, respectively. 250C is the temperature in the column. Silica gel 60F 254 pre-coated plates (10 x 10 cm) were used with toluene: acetone: formic acid (38:10:5) as the solvent system for HPTLC analysis of quercetin obtained from the tender leaves of guava. The λ max was observed in the U.V. spectrum of the isolated compound (quercetin) on three standard wavelengths: 212 nm, 256 nm, and 372 nm. An effort can be made to produce a new analytical method that will be cost-effective and time-saving.

This study aimed to explore the phytochemical profile, heavy metal composition, in silico aphrodisiac potential, and ADMET study of Gardenia erubescens due to its folkloric acclaimed aphrodisiac use. The phytochemicals were quantified gravimetrically while the identification of bioactive compounds was carried out using a combined Gas spectrophotometer-mass spectrophotometer (GC-MS). Heavy metals were quantified using an atomic absorption spectrophotometer while the aphrodisiac and ADMET studies were in silico. The result showed the presence of alkaloids (22.33% ± 1.45), saponins (20.17% ±1.88), glycosides (0.55% ±0.03), and flavonoids (32.67% ±1.45), with the absence of steroids and terpenoids. GC-MS analysis identified 25 compounds with linoleic acid having the highest peak area (28.01%) next to palmitic acid (14.08%). Chromium, Cadmium, and Lead were present in concentrations of 0.145 ± 0.03, 0.001 ± 0.00, and 0.065 ± 0.03 ppm respectively. Ethyl D-glucopyranoside had the least BA (-8) and Ki (1.35 µM) docked with human arginase II while Tyrosinol had the least BA (-6.2) and Ki (28.21 µM) docked with phosphodiesterase 5 though both were higher than Sildenafil citrate. All the top docked compounds were predicted to be neither substrates nor inhibitors of P-glycoproteins and cytochrome P450 enzymes without CNS permeability and hepatotoxicity. Conclusively, the present study supports the folkloric aphrodisiac application of G. erubescens, and the heavy metals level was below the acceptable regulatory level, thus, might be safe for occasional use. Additionally, the identified compounds might be considered a novel source of therapeutics against erectile dysfunction.

Any product generated from food sources that offer additional health advantages over and above the essential nutritional content present in foods is referred to as a nutraceutical under the broad umbrella term. The catechins in Camellia sinensis (Theaceae) namely (-)-epicatechin, (-)-epicatechin-3-gallate, (-)-epigallocatechin, and (-)-epigallocatechin-3-gallate (EGCG), which can be used as nutraceuticals in food or as a component of food items has been discussed. Catechins being polyphenols and antioxidants are found to have a wide range of therapeutic application like weight loss, anticancer, anti-inflammatory, and a few more therapeutic applications, through various mechanisms like stimulating AMP-activated protein kinase, enhanced apoptosis, decreased expression of interleukin (IL)-6 and IL-8. The most recent method for extracting catechins include combining the extraction processing of PEF or IPL with Subcritical water extraction. Food additives have been mixed with green tea extracts to develop a desired formulation like chewing gum and capsule. As green tea catechins are a beneficial phytoconstituents to improve overall health, its prospects include formulation of a gelatin gummy formulation which will improve its palatability by masking the bitter taste. Gelatin gummy formulation can be carried conveniently and will provide easy access to the consumer as compared to green tea. Furthermore, we found a scope to develop an analytical method for EGCG and carry out its validation by HPLC which will be more reliable and cost-efficient in comparison to the existing UHPLC methods for EGCG.

Medication and food are frequently consumed together. However, some foods have interactions with medicines by changing key regulators of systemic medication availability. Their consumption is linked to interactions with a wide range of medications. One of the most significant beverages that can be harmful when combined with certain medicines is grapefruit juice. Furanocoumarins' mechanism-based suppression of intestinal cytochrome P450 3A4, which increases the bioavailability of drugs that are substrates, is the main mechanism by which interactions are mediated. There have also been reports of interactions between grapefruit products and uptake transporters such as P-glycoprotein (P-gp) and organic anion-transporting polypeptides (OATPs). It has been suggested that polyphenolic substances like flavonoids are what cause the interactions between P-gp and OATP. The amounts of furanocoumarins and flavonoids in the grapefruit product, the amount of juice consumed, the medium PH, and the inherent diversity of enzymes and transporter components in humans can all have an impact on the processes and magnitudes of interactions. In this review, we are going to shed light on clinical trials showing grapefruit juice-drug interactions and what should the health provider do for better clinical care.
