Structural elucidation of specialized metabolites or natural plant products, especially the stereochemical features chiral bioactive metabolites, is most important stage for all investigations in pharmacognosy and phytochemistry. Numerous methods have been established to solve absolute configuration including direct such as X-ray diffraction, chiroptical spectroscopy, stereo-controlled partial total organic synthesis, chemical correlation by simple reactions derivatization, well indirect using a standard compound derivatizing agent with known configuration, example, nuclear magnetic resonance utilization anisotropic effects agents. Once relative product resolved, stereochemistry can be determined assistance spectroscopies supported quantum mechanical-NMR prediction shifts, scalar coupling constants simulation optical rotatory dispersion, addition electronic vibrational circular dichroism spectra. This review summarizes practical employed assignment products selected examples focused on multichiral center small molecules from mega-diverse Brazilian Mexican flora.

In the study, water, ethanol, methanol, dichloromethane, and acetone extracts of Asparagus officinalis L. were obtained by maceration. DPPH⋅, ABTS⋅+ , FRAP, CUPRAC methods determined antioxidant capacities all extracts. Moreover, in vitro effects on acetylcholinesterase (AChE), butyrylcholinesterase (BChE), carbonic anhydrase (CA)-I, CA-II α-Glycosidase investigated. At a 10 μg/ml concentration, extract with highest Fe3+ reduction capacity was ethanol (AE), Cu2+ (AA). AE for AChE (IC50 =21.19 μg/ml) : 70.00 μg/ml), methanol (AM) BChE =17.33 CA-I II =79.65 36.09 μg/ml, respectively) showed most potent inhibition effect.

Background: Obesity is a serious public health problem contributing to development of several diseases, including hyperlipidemia, hyperglycemia, and hypertension. The plant Eriobotrya japonica (loquat) has been used in traditional Chinese medicine treat many ailments healers it reduce weight. Objectives: To examine the potential anti-obesity hypolipidemic effects ethanol extract loquat rats. Materials Methods: Loquat leaves, fruits, or seeds were extracted with ethanol. About 96 Wistar male rats fed either normal rat diet (normal control group; group 1) high-fat (HFD) for 12 weeks (obese; groups 2−12). Obese divided into11 as follows: (obese control: 2) positive which received reference drug atorvastatin: 3). Groups (4−6), (7−9), (10−12) given seed, leaf, fruit extract, respectively, at 40,100, 400 mg/kg. Body weight, serum glucose, lipid profile, creatinine, liver enzymes, albumin, total protein measured weekly. Results: HFD consumption significantly increased body weight cholesterol (TC), triglycerides (TGs), low-density lipoprotein (LDL), very-low density (VLDL), glucose decreased HDL compared diet. also glutamic-oxaloacetic transaminase (GOT), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP) creatinine but albumin protein.
