【 摘 要 】

Microstylis wallichiiLindl. is a Rasayana and belongs to the “Astverga”.It is an important medicine traditionally known since Vedic period but study on its phytoconstituents is very limited. Metal content and volatile constituentsin M. wallichii(family Orchidaceae) collected from Uttarakhand were analyzed by Atomic Absorption Spectrophotometer and GC and GC-MS respectively. Chemical analysis revealed that wildM. wallichiicontained 6.48 ppm Cu, 43.00 ppm Zn, 35.00 ppm Mn, 331.00 ppm Fe, 21600.00 ppm K, 9000.00 ppm Ca, 2800.00 ppm Mg, 198.00 ppm Al, 26.70 ppm Ba, 55.60 ppm B, 0.30 ppm Mo, 156.00 ppm Cl. Fatty acids analysis revealed the presence of the following constituents-linoleic acid (18:2ω6) 61.20% (w/w), α-linolenic acid 18.10% (w/w), oleic acid 12.00 % (w/w), palmitic acid (16:0) 6.00% (w/w), stearic acid (18:0) 2.10% (w/w), γ-linolenic acid (18:3ω6) 2.20% (w/w), eicosanoic acid (20:0) 0.81 % (w/w), eicosenoic acid (20:1) 0.42% (w/w) and eicosadienoic acid (20:2) 0.04% (w/w). CultivatedM. wallichiicontained 7.18 ppm Cu, 49.50 ppm Zn, 37.00 ppm Mn, 352.45 ppm Fe, 23000.00 ppm K, 13000.00 ppm Ca, 5300.00 ppm Mg, 217.50 ppm Al, 37.50 ppm Ba, 59.70 ppm B, 0.27 ppm Mo, 148.00 ppm Cl. Analysis of fatty acids reported following constitutents of cultivatedM. wallichii -linoleic acid (18:2ω6) 65.23% (w/w), α-linolenic acid 15.50% (w/w), oleic acid 14.87 % (w/w), palmitic acid (16:0) 5.90% (w/w), stearic acid (18:0) 2.50% (w/w), γ-linolenic acid (18:3ω6) 1.87% (w/w), eicosanoic acid (20:0) 0.69 % (w/w), eicosenoic acid (20:1) 0.52% (w/w) and eicosadienoic acid (20:2) 0.07% (w/w). Other chemical constituents which were isolated fromwild and cultivatedM. wallichiiwere vitamins α–tocopherol and γ-tocopherol 12.00-9.80 ppm and 695.00-786.7 ppm respectively while terpenoids 18.00-20.50%. It has an acid value of 1.20-1.39 and saponification value of 103.00-110.50.
