Over 100-1000 microbial species reside in the human gut, where they predominantly influence the host's internal environment and, thus, have a significant impact on host health. Probiotics are best characterized as a microbe or a group of microbes that reside in the gut and support the body's internal microbiota. Probiotics are linked to increased health advantages, including better immune function, improved nutritional absorption, and protection against cancer and heart-related illnesses.

Homalomena aromatica is a herb of tremendous ethnomedicinal importance to various communities residing in northeast India. In this study, a high-performance thin-layer chromatography-based densitometric method was developed for identification, quantification and stability study of linalool. Mass spectrometry was hyphenated to HPTLC for streamlining the method.

Scientific pieces of evidence support the pharmacological activity of for its antidepressant, analgesic, anticonvulsant and antioxidant effect. Here, we evaluate the bioactivity of essential oil and the various polarity-based solvent partitioned fractions obtained from for anti-amnesia, anxiolytic and antidepressant activities using Elevated plus maze and Morris water maze models. The cold maceration technique using methanol was adopted for extraction from dried powdered rhizomes and essential oil was extracted by hydrodistillation method.

Article Synopsis
  • Malaria, particularly severe cases caused by the P. falciparum species, is being studied for treatments using the ethnomedicinal plant Coptis teeta found in northeast India.
  • The effectiveness of methanol extracts of C. teeta was tested in lab settings, revealing a highly potent IC50 value, and in silico studies identified noroxyhydrastinine as a promising candidate with better binding affinity than chloroquine.
  • The findings suggest that noroxyhydrastinine could potentially be developed further as an effective antimalarial agent based on its strong interactions with malaria-causing proteins and stability in binding.

The high polarity of the protoberberine alkaloids present in Coptis teeta has made it difficult to quantify the alkaloids. This study was designed to develop and validate a thin-layer chromatography (TLC) densitometric-based method using high-performance thin-layer chromatography for quantification of berberine. The separation was achieved in a solvent system consisting of butanol:ethyl acetate:formic acid:water by volume on TLC aluminum plate precoated with silica gel 60 F254.

Bora rice, a glutinous rice, is grown in Assam (a north eastern state of India) and is used traditionally for various purposes. The rationale of this study was to prepare and to assess Metformin loaded mucoadhesive spray dried microspheres using locally grown Bora rice powder. Metformin loaded microspheres were prepared using Bora rice and sodium alginate by spray drying method.
