The betaine content of Saliconia herbacea L. was determined by reverse-phase high performance chromatog-raphy on a C_(18) column. A 50% methanol extract was passed through a anion exchanger Ambelite IRA 400 (quaternary ammonium type, OH-) column and a strong cation exchanger Ambelite IR 120 (sulfonic acid type, $H^+$) column to remove amino acids, zwitter ions which are interfere with betaine analysis. The betaine extract was derivatized with 18-crown-6-ether and 4-bromophenacyl bromide (PBPB) for UV-labelling. Betaine in Saliconia herbacea L. was analysed on a mobile phase contained 13 mM sodium heptane sulfonic acid and 5 mM $Na_2SO_4$ in deionized water by isocratic elution for 30 min. The recovery ratio of betaine from Saliconia herbacea L. extract was 83.6%. The mean betaine value for Saliconia herbacea L. determined by the described method is 4.85 mg/mL with a standard deviation of 0.127.

Effects of medicinal herbs on the improvement of muscular strength along with the related fatigue factors were evaluated in SD rats. Nine types of treatment groups were fed diets supplemented with 1% herb hot-water extracts (Liriope spicata (LS), Schizandra chinensis (SC), Acanthopanax sessiliflorus (AS), Saliconia herbacea (SH), Eucommia ulmoides (EU), Lycium chinensis (LC), Panax ginseng (red ginseng) (PG), Polygonum multifloum (PM), Glycyrrhizae uralensis (GU)) for 4 weeks. The muscular strength of all groups were measured weekly for 4 weeks. After 4 weeks serum was collected and liver dissected out for the analysis of glycogen and fatigue factors. The liver glycogen contents of all treatment groups ($21.0{\sim}25.9mg/g$) were higher than that of control group (18.1 mg/g). A significantly increase of muscular strength in the fourth week were found in the AS (282.5 gf), SH (277.4 gf), PG (287.2 gf) groups (p<0.05). LS (7.88 mg/dL), SC (7.85 mg/dL), AS (7.64 mg/dL), EU (7.54 mg/dL), LC (7.81 mg/dL) and PG (7.75 mg/dL) groups were significantly reduced in serum inorganic phosphorus concentration measured after 4 weeks (p<0.05). Serum lactate levels of treatment groups ($8.61{\sim}12.18{\mu}g/dL$) were significantly lower than that of control group ($17.45{\mu}g/dL$). These results suggest that medicinal herbs enhanced muscular strength of rats by delaying accumulation of muscular fatigue factor.
