Abstract

Emblica fruits have long been endowed with many pharmacological properties, which are attributable to their rich vitamin C content. A recent report that Emblica fruits do not contain ascorbic acid, but contain two hydrolysable low molecular weight tannins with antioxidant attributes, thus challenging the long-standing belief that amla fruits owe their potential pharmacological activity to their vitamin C content. The present study examines the vitamin C content of Emblica fruits by employing a specific enzymatic method in addition to the liquid chromatographic and the conventional spectrophotometric procedures to assess the extent of over-estimation, if any. The specific enzymatic procedure employed here indicated that Emblica fruits do not totally lack vitamin C as claimed and nevertheless, the conventional colorimetric method over-estimates the same in these fruits. A similar determination of vitamin C content in a few other conventionally rich plant sources of this vitamin indicated that over-estimation of vitamin C by colorimetric method is also evident in guava fruits (Psidium guajava) and amaranth leaves (Amaranthus gangeticus), but the extent was lower than that in the Emblica fruits. Thus, the discrepancy in the reported value of this nutrient is not limited to Emblica fruits alone, but can be found in other plant systems also. This study also examined the extent of retention of this vitamin after drying of the Emblica fruits and evidenced that shade drying did not improve the same as compared to sun drying. However, the amount of vitamin C retained in the dried Emblica fruits is comparable to the amounts present in several other fresh fruits.

  • The vitamin C content of individual plant species is highly variable due to factors including place of cultivation, harvesting time, weather conditions, latitude, genotype, agrotechnology, analytical method, and processing.

    “As can be seen from Table 1, the vitamin C content of individual plant species is highly variable due to many factors, including place of cultivation, harvesting time (ripening stage), weather conditions, latitude, genotype, agrotechnology, analytical method used for determination, and processing [24,32,33,34,35].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
