Pharmacognostic, Phytochemical and Physicochemical Studies of Piper Nigrum Linn. Fruit (Piperaceae)

Abstract

Piper species are reported to have great medicinal value in Indian medicine. Fruits of Piper nigrum Linn is commonly known as "Kalimiri" belongs to the family of Piperaceae and widely used as a pungent condiment. Traditionally it is used as antipyretic, diuretic, aphrodisiac, immune-stimulant, antioxidant, hepatoprotective, digestive, rubefacient, counter irritant, antiseptic, antispasmodic agent. Present work is related to standardization of Piper nigrum by using Pharmacognostic (Macroscopy, Cytomorphology, Physical constants) and Photochemical study of fruit. All parameters were studied according to the WHO and Pharmacopoeial guidelines to standardize the Piper nigrum.

Powder Microscopic, Physicochemical, HPTLC and Antioxidant Studies on Noccik Kudinir Chooranam – A Polyherbal Siddha Formulation

“…The main reason behind the need for the evaluation of crude drug microscopically is to rule out any adulteration and substitutions if any. Microscopic examination of the powdered compounded formulation revealed the presence of elongated epidermal cells with anamocytic stomata and spiral vessels which is in accordance to the previous studies carried out in A. sativum; [10][11][12][13] thin epidermal cells with cyclocytic stomata, glandular trichomes with pearl glands and the prismatic crystals obtained during powder microscopy can be attributed to P. betel leaves and affirms the former studies; [14][15][16][17] broad and rectangular sclereids seen in abundance arranged laterally, bearer cells, starch grains granules both agglomerated and scattered and the vascular elements can serve as a diagnostic tool for identifying P. nigrum fruits and were consistent HPTLC finger print profile of ethyl acetate solubles of water extract of NKC (Figure 3), under 254 nm showed major peaks (12,11 and 9) HPTLC finger print of alkaloid fraction (Figure 3), at 254nm showed major peaks (11,14 and 13) at Rf 0.65(38.88%), 0.96(22.18%) and 0.83(12.83%); under 366nm, showed major peaks (9,8 and 6) at Rf 0.95(47.39%), 0.91(14.34%) and 0.65(10.10%). As the TLC plate showed two alkaloid spots at 0.63 and 0.97, finger print not documented after derivatization with Dragendorff 's reagent.…”

Analisis Kemiripan 20 Aksesi Temu Ireng (Curcuma aeruginosa Roxb.) Berdasarkan Warna Rimpang, Hasil Ekstrak, dan Kandungan Fitokimia

“…Adanya warna biru merupakan warna yang khas pada rimpang temu ireng (Jose dan Thomas, 2014), yang menjadi pembeda dengan rimpang lain seperti temulawak (Cahyono et al, 2011) dan kunyit (Kadam et al, 2013) yang memiliki warna dominan kuning karena adanya kandungan senyawa kurkuminoid.…”

Phytochemical Investigation on Withania Somnifera Root Marc Generated in Ayurvedic Industry

“…The extractive percentage was calculated. Preliminary phytochemical analysis was carried out on each extracts separately and compared with that of herb [17][18][19][20][21][22][23][24][25] . …”
