The study was to identify tree foliages fed to dairy animals in Mizoram, to screen and quantify the phytochemicals and to survey traditional medicinal uses. Surveys conducted on 45 dairy farmers of 15 randomly selected villages of RDBs of Aizawl district, Mizoram (namely, Tlangnuam, Thingsulthiah and Aibawk). Aqueous extracts of representative leaf samples were made for phytochemical screening and quantification by following different procedures. The study revealed usages of 41 different tree foliages out of which 21 were evergreen.

Phytochemicals are chemicals of plant origin, produced through primary or secondary metabolism of plants. Phytochemicals have become of great interest owing to their diverse applications. In the study five plant sources available locally and abundantly were selected to screen phytochemicals available in their leaves for testing their anti-microbial property for textiles. Leaf extracts were prepared using 70% ethanol and distilled water.

The plant Acacia catechu (L.f) Willd hydroethanolic leaf extract was subjected to qualitative and quantitative phytochemical screening, HPTLC and GCMS analysis. The phytochemical analysis revealed the presence of carbohydrates, proteins, flavonoids, total phenolics, glycosides, total free amino acids, tannins, alkaloids and thiols. The secondary metabolites like flavonoids, tannins and total phenolics were quantified as 82μg/ml, 67.5μg/ml and 42.5μg/ml.

The present study was conducted to detect the presence of phytochemicals in plant extracts pertaining to Meghalaya and their efficacy against Alternaria brassicicola, a causal agent of black leaf spot of cauliflower. Phytochemical screening of plant extracts studied showed that winged prickly ash and ginger had almost all the phytochemicals tested but least phytochemicals was observed in black pepper. Phytochemicals such as alkaloids and flavonoids were presence in almost all plant extracts.

Plants have been known to be a reservoir of secondary metabolites which are being exploited as source of bioactive substance for various pharmacological purposes. In the present study, fresh leaf extracts of hibiscus were prepared using ethanol, methanol and distilled water. The extracts were assessed for the presence of various classes of phytochemicals by subjecting to different tests and total phenolic content of each extract was carried out using FCR method. Results revealed that all the extracts of hibiscus contained alkaloids, flavonoids and tannins.
